QuickCommerce API — Printing Press CLI

Prerequisites: Install the CLI

This skill drives the quickcommerce-pp-cli binary. You must verify the CLI is installed before invoking any command from this skill. If it is missing, install it first:

1. Install via the Printing Press installer. It defaults binaries to $HOME/.local/bin on macOS/Linux and %LOCALAPPDATA%\Programs\PrintingPress\bin on Windows:

   npx -y @mvanhorn/printing-press-library install quickcommerce --cli-only

2. Verify: quickcommerce-pp-cli --version
3. Ensure the reported install directory is on $PATH for the agent/runtime that will invoke this skill.

If the npx install fails (no Node, offline, etc.), fall back to a direct Go install (requires Go 1.26.6 or newer). This installs into $GOPATH/bin (default $HOME/go/bin), so add that directory to $PATH instead:

go install github.com/mvanhorn/printing-press-library/library/commerce/quickcommerce/cmd/quickcommerce-pp-cli@latest

If --version reports "command not found" after install, the runtime cannot see the binary directory on $PATH. Do not proceed with skill commands until verification succeeds.

QuickCommerce CLI covers the provider's REST and hosted-MCP surface while adding a local mirror for repeatable analysis. Use history, fastest delivery, credit planning, stale-data checks, and unit-price views to turn location-sensitive responses into decisions.

When to Use This CLI

Use this CLI for location-aware product search, price and stock comparisons, delivery ETA decisions, and repeatable local analysis across Indian commerce platforms. It is especially useful when an agent needs bounded JSON, credit-aware fan-out, and historical context instead of one ephemeral API response.

Anti-triggers

Do not use this CLI for:

• Do not use this CLI to place orders, manage carts, or perform checkout; the API exposes read-only product and delivery data.
• Do not use the local mirror as proof of current availability without checking its age; refresh paid observations deliberately.
• Do not use this CLI for platforms or locations outside the documented QuickCommerce API coverage.

Unique Capabilities

These capabilities aren't available in any other tool for this API.

Local state that compounds

• history prices — Query local observations to see price, stock, rating, and availability movement over time.

  Choose this when an agent needs to explain what changed instead of fetching only the current value.

  quickcommerce-pp-cli history prices --item 501346 --since 30d --agent

• history diff — Show the field-level changes between the latest saved observations.

  Choose this after ingestion when an agent needs a precise price, stock, or ETA delta.

  quickcommerce-pp-cli history diff --item 501346 --latest 2 --agent

• mirror ingest — Persist real QuickCommerce command responses and metadata into the local SQLite mirror.

  Choose this when an agent wants future history, offline search, or a reproducible observation record.

  quickcommerce-pp-cli mirror ingest --stdin --agent

Decision-ready comparisons

• delivery fastest — Rank currently available delivery options while preserving closed or unparseable platforms.

  Choose this when an agent must recommend a viable fastest platform rather than list raw ETA rows.

  quickcommerce-pp-cli delivery fastest --location 12.9021,77.6639 --agent

• mirror coverage — Report observed, missing, and stale platform coverage for a location.

  Choose this when an agent needs to know whether a location has usable evidence across platforms.

  quickcommerce-pp-cli mirror coverage --location 12.9021,77.6639 --agent

• prices value — Compare price per unit from explicit pack quantities without guessing missing units.

  Choose this when the cheapest sticker price may not be the cheapest comparable quantity.

  quickcommerce-pp-cli prices value --query milk --location 12.9021,77.6639 --agent

Agent-native safety

• requests plan — Calculate fan-out credit cost and affordability before making paid platform requests.

  Choose this before an agent launches a multi-platform search or ETA fan-out.

  quickcommerce-pp-cli requests plan --platforms blinkit,zepto --operation search --agent

• mirror stale — Find saved product and ETA observations that are older than a chosen trust window.

  Choose this before making decisions from local data whose location-sensitive freshness matters.

  quickcommerce-pp-cli mirror stale --max-age 24h --agent

Finding the right command

When you know what you want to do but not which command does it, ask the CLI directly:

quickcommerce-pp-cli which "<capability in your own words>"

which resolves a natural-language capability query to the best matching command from this CLI's curated feature index. Exit code 0 means at least one match; exit code 2 means no confident match — fall back to --help or use a narrower query.

Recipes

Compare milk prices

quickcommerce-pp-cli comparison --query milk --platforms BlinkIt,Zepto,Swiggy --latitude 12.9021 --longitude 77.6639 --agent --select results

Ask for only the cross-platform result map instead of the full response envelope.

Plan a paid fan-out

quickcommerce-pp-cli requests plan --platforms blinkit,zepto,swiggy --operation search --json

Check the expected credit cost before making a multi-platform search.

Rank delivery speed

quickcommerce-pp-cli delivery fastest --location 12.9021,77.6639 --agent

Rank viable open platforms while retaining unavailable rows for explanation.

Find stale observations

quickcommerce-pp-cli mirror stale --max-age 24h --json

Detect local data that needs a deliberate refresh.

Inspect an item trend

quickcommerce-pp-cli history prices --item 501346 --since 30d --agent

Review saved price, inventory, and availability movement for one item.

Auth Setup

Set QUICKCOMMERCE_API_KEY to the API key from the QuickCommerce dashboard. The CLI sends it as X-API-Key and keeps paid calls explicit; platform discovery is available without a key.

Run quickcommerce-pp-cli doctor to verify setup.

Agent Mode

Add --agent to any command. Expands to: --json --compact --no-input --no-color.

• Pipeable — JSON on stdout, errors on stderr

• Filterable — --select keeps a subset of fields. Dotted paths descend into nested structures; arrays traverse element-wise. Critical for keeping context small on verbose APIs:

  quickcommerce-pp-cli comparison --query milk --platforms BlinkIt,Zepto --latitude 12.9021 --longitude 77.6639 --agent --select query,platforms,lat

• Previewable — --dry-run shows the request without sending

• Offline-friendly — sync/search commands can use the local SQLite store when available

• Non-interactive — never prompts, every input is a flag

• Read-only — do not use this CLI for create, update, delete, publish, comment, upvote, invite, order, send, or other mutating requests

Response envelope

Commands that read from the local store or the API wrap output in a provenance envelope:

{
  "meta": {"source": "live" | "local", "synced_at": "...", "reason": "..."},
  "results": <data>
}

Parse .results for data and .meta.source to know whether it's live or local. A human-readable N results (live) summary is printed to stderr only when stdout is a terminal AND no machine-format flag (--json, --csv, --compact, --quiet, --plain, --select) is set — piped/agent consumers and explicit-format runs get pure JSON on stdout.

Paths and state

Agents should treat the CLI's path resolver as part of the runtime contract:

• Use --home <dir> for one invocation, or set QUICKCOMMERCE_HOME=<dir> to relocate all four path kinds under one root.

• Use per-kind env vars only when a specific kind must diverge: QUICKCOMMERCE_CONFIG_DIR, QUICKCOMMERCE_DATA_DIR, QUICKCOMMERCE_STATE_DIR, QUICKCOMMERCE_CACHE_DIR.

• Resolution order is per-kind env var, --home, QUICKCOMMERCE_HOME, XDG (XDG_CONFIG_HOME, XDG_DATA_HOME, XDG_STATE_HOME, XDG_CACHE_HOME), then platform defaults.

• config contains settings like config.toml and profiles. data contains credentials.toml, data.db, cookies, and auth sidecars. state contains persisted queries, jobs, and teach.log. cache contains regenerable HTTP/cache files.

• Stored secrets live in credentials.toml under the data dir. Existing legacy config.toml secrets are read for compatibility and leave config.toml on the first auth write.

• Run quickcommerce-pp-cli doctor --fail-on warn to surface path and credential-location warnings. agent-context exposes a schema v4 paths block for agents that need the resolved dirs.

• For MCP, pass relocation through the MCP host config. The MCP binary does not inherit CLI flags:

  {
    "mcpServers": {
      "quickcommerce": {
        "command": "quickcommerce-pp-mcp",
        "env": {
          "QUICKCOMMERCE_HOME": "/srv/quickcommerce"
        }
      }
    }
  }

Fleet precedence: an inherited per-kind env var overrides an explicit --home for that kind. Use QUICKCOMMERCE_HOME or per-kind vars as durable fleet levers, and use --home only for a single invocation. Relocation is not reversible by unsetting env vars; move files manually before clearing QUICKCOMMERCE_HOME, or doctor will not find credentials left under the former root.

Automatic learning

This CLI ships a self-capturing learning loop. The CLI does its own bookkeeping: every invocation is journaled locally, a failed flag followed by a corrected retry auto-derives a flag_alias candidate, and a teach on a query family without a playbook auto-synthesizes a playbook_candidate from the session's journal. Your job is judgment only: recall first, act on surfaced candidates, teach the final answer, playbook amend when you observe a correction. You never record failures by hand.

Step 1: recall before any discovery

Before list/search/drill commands on a new user question, run:

# Agent input must already be structuralized and identifier-free. Do not
# read from stdin: agent shells are noninteractive and a user question can
# contain names, emails, phone numbers, or account identifiers.
#
# Capture the value with your Write tool, not a shell heredoc: a heredoc's
# terminator is matched by exact line content, so if the value itself
# contains a line equal to the delimiter, the heredoc closes early and
# whatever follows that line runs as literal shell commands. Writing the
# value to a file with a non-shell tool sidesteps shell parsing of it
# entirely -- there's no delimiter to spoof, and reading it back with
# `read` from file redirection has no terminator-matching step to game.
# 1. Write tool -> a scratch file, containing exactly:
#    compare product prices across platforms
STRUCTURAL_QUERY_FILE=$(mktemp)
# (Write tool call targets $STRUCTURAL_QUERY_FILE here)
IFS= read -r STRUCTURAL_QUERY < "$STRUCTURAL_QUERY_FILE"
rm -f "$STRUCTURAL_QUERY_FILE"
quickcommerce-pp-cli recall "$STRUCTURAL_QUERY" --agent

The response envelope:

{
  "query": "...",
  "normalized": "<normalized form>",
  "query_entities": ["..."],
  "found": true | false,
  "match_score": 0.0,
  "results": [
    { "resource_id": "...", "resource_type": "...", "venue": "...",
      "confidence": 2, "entity_match": "exact|partial|unknown",
      "source": "taught|preseed|pattern", "warnings": ["..."] }
  ],
  "mismatches": [ /* only when --debug-mismatches */ ],
  "warnings": [ /* top-level */ ],
  "candidates": [
    { "id": 12, "class": "flag_alias | playbook_candidate",
      "summary": "...", "sightings": 3, "last_seen": "...",
      "rationale": "...",
      "next_action": ["<trial command>", "quickcommerce-pp-cli learnings confirm 12"] }
  ],
  "playbook": {
    "query_family": "...",
    "playbook": {
      "steps": [ { "cmd": "<command with {slot} substitution>", "purpose": "..." } ],
      "entity_slots": ["$ENTITY"],
      "expected_tool_calls": 3
    },
    "slots_resolved": { "$ENTITY": { "token": "<live token>", "canonical": "<canonical>" } },
    "notes": "<workarounds + gotchas for this query family>"
  },
  "notes": "<duplicate surface for non-playbook callers>"
}

Empty-store short-circuit: if the store has no learnings, playbooks, or candidates yet (recall finds nothing and learnings list and learnings candidates are both empty), skip recall for the rest of this session instead of taxing every query; resume recall-first once something has been taught.

Step 2: decision tree

Read candidates, playbook, notes, results[0], and warnings in that order:

if Candidates present (warnings include "candidates_present"):
    -> candidates are try-then-confirm, never facts. Follow each candidate's
       two-step next_action verbatim: run the trial command first, then run
       `learnings confirm <id>` only after the trial verified the behavior.
       Reject a wrong candidate with `learnings reject <id>`.
    -> NEVER re-teach something recall surfaced as a candidate; confirm or
       reject that candidate instead of teaching a duplicate.
    -> candidates ride alongside playbooks and resource hits, not instead of
       them; continue with the branches below after acting on them.

if Playbook present:
    -> READ Playbook.notes verbatim FIRST (workarounds + gotchas the CLI surface doesn't expose)
    -> replay Playbook.steps in order, substituting Playbook.slots_resolved entries
       for the entity slot tokens. If a step's slot is unresolved, fall back to
       discovery for that step only.
    -> the Playbook's expected_tool_calls is a budget; if you find yourself running
       materially more, record the divergence via `quickcommerce-pp-cli playbook amend`
       at end-of-session.

elif Notes present (no Playbook):
    -> read Notes verbatim before any discovery step; they carry known gotchas
       for this query family even when no structured choreography exists yet.

elif Found AND Results[0].EntityMatch == "exact" AND Results[0].Confidence >= 2:
    -> skip discovery; fetch live data for Results[*].ResourceID in parallel

elif Found AND Results[0].EntityMatch == "partial":
    -> candidate hint, NOT a hit; read the resource title to validate before trusting

elif (any row in Mismatches[] when --debug-mismatches was passed):
    -> treat as cold start; the stored learning is for a different entity
       (different canonical resolved from query_entities)

else:  // Found == false, no playbook, no notes
    -> cold start; run discovery normally; teach the answer afterward (Step 4).
       If the family has no playbook yet, that teach auto-synthesizes a
       playbook candidate from this session's journal - you do not need to
       record one by hand.

Playbook and Notes are orthogonal to the per-resource path. A recall response can carry both a Playbook AND a Results[] hit - use both: the Playbook tells you which choreography to run; the resource hits short-circuit specific steps. Default to skipping mismatches; pass --debug-mismatches only when investigating cold-start surprises.

Candidate judgment details: learnings confirm <id> prints the candidate's full payload before materializing it - check that the printed payload matches the behavior you verified. learnings reject <id> tombstones the derivation signature so the same candidate does not resurface. The envelope carries only the few candidates worth acting on now; quickcommerce-pp-cli learnings candidates lists the full open set.

Graceful degradation: if learnings confirm is an unknown command, you are driving an older binary - ignore the candidates guidance and follow the rest of the protocol.

Step 3: always read warnings

• low_confidence: row exists at confidence<2. Treat as a hint, not a skip-discovery hit.
• resource_not_in_store: the local store doesn't have the resource the learning points at. The match validator couldn't classify entities — direct-fetch and re-evaluate.
• cross_alias_match (per-result): the row was taught under a different alias and matched the live query's canonical via entity_lookups (e.g., a "USA" teach satisfying a "United States" recall). Trust the resource_id.
• similar_shape_different_entity:<canonical> (top-level): a structurally matching row exists but its canonical entity differs from the live query's. Treated as cold start; the warning carries the conflicting canonical as a hint, but the row is NOT promoted into Results.
• ambiguous_alias (top-level): a single query entity resolved to multiple canonicals (e.g., "Cards" → Arizona Cardinals + St. Louis Cardinals). Surface the ambiguity from context before committing to a resource.
• candidates_present (top-level): the envelope carries a candidates section. Handle it via the candidates branch in Step 2 before anything else.
• lookup_refresh_available (top-level): an entity in the query has no lookup row yet, but synced data could provide one. Run quickcommerce-pp-cli sync to refresh entity lookups.
• Top-level no_learnings_for_query_family: the table had no rows above the Jaccard floor. Pure cold start.
