At a glance

Understand Kraken API rate limits and adapt agent behavior when limits are hit.

  • Works in 3 steps: Spot REST Counter → Spot Trading Engine (per-pair) → Futures Cost Budget
  • Tasks that involve Rate limiting
  • SKILL.md covers How Rate Limiting Works, Kraken's Rate Limit Systems and Agent Strategies
  • Calls jq; reaches docs.kraken.com

What it does

Kraken Rate Limits is an agent skill from krakenfx/kraken-cli. Understand Kraken API rate limits and adapt agent behavior when limits are hit.

Its SKILL.md is about 990 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Backend & APIs, covering Rate limiting. The repository describes itself as: The first AI-native CLI for trading crypto, stocks, forex, and derivatives. The licence is MIT.

When your agent uses it

  • Tasks that involve Rate limiting

Example prompts

  • “/kraken-rate-limits”

Workflow steps

3 steps, taken from the step headings in SKILL.md.

  1. Spot REST Counter
  2. Spot Trading Engine (per-pair)
  3. Futures Cost Budget

What it can do on your machine

Read from SKILL.md and the folder at commit aa56e59. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • jq

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • docs.kraken.com

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Kraken Rate Limits loads about 994 tokens when it runs. Until then it costs about 25 tokens; SKILL.md has 368 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~25
When it runs · the whole SKILL.md, loaded when a task matches
~994

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

kraken-rate-limits

Use this skill for:

  • understanding Kraken's rate limit systems (Spot REST, trading engine, Futures)
  • adapting agent behavior when rate limit errors occur
  • choosing optimal request patterns (WebSocket vs REST, batch vs individual)

How Rate Limiting Works

The CLI does not pre-throttle or retry rate-limited requests. The Kraken API server enforces rate limits. When a limit is hit, the CLI returns the error immediately with structured fields:

json
{
  "error": "rate_limit",
  "message": "Spot REST API rate limit exceeded ...",
  "suggestion": "Wait 5-15 seconds before retrying. ...",
  "retryable": true,
  "docs_url": "https://docs.kraken.com/api/docs/guides/spot-rest-ratelimits/"
}

Read the suggestion field to understand what limit was hit and how to adapt.

Kraken's Rate Limit Systems

1. Spot REST Counter

Counter-decay model. Each call adds to a counter; the counter decays over time.

TierMax CounterDecay Rate
Starter150.33/s
Intermediate200.5/s
Pro201.0/s

Most calls cost 1 point. Ledgers, trade history, and query-ledgers cost 2. AddOrder and CancelOrder are excluded from this counter (they use the trading engine limiter instead).

Docs: https://docs.kraken.com/api/docs/guides/spot-rest-ratelimits/

2. Spot Trading Engine (per-pair)

Separate per-pair counter with penalties for short-lived orders:

TierThresholdDecay Rate
Starter601/s
Intermediate1252.34/s
Pro1803.75/s

Cancel within 5 seconds costs +8, amend within 5 seconds costs +3. Let orders rest longer to reduce cost.

Docs: https://docs.kraken.com/api/docs/guides/spot-ratelimits

3. Futures Cost Budget

Cost-based system with two separate pools:

  • /derivatives endpoints: budget of 500 per 10 seconds. sendorder costs 10, editorder costs 10, cancelorder costs 10, batchorder costs 9 + batch size, cancelallorders costs 25, accounts costs 2.
  • /history endpoints: pool of 100 tokens, refills at 100 per 10 minutes.

Agent Strategies

Prefer WebSocket over REST polling

Streaming does not consume REST rate limit points. For real-time data, always prefer:

bash
kraken ws ticker BTC/USD -o json 2>/dev/null
Use batch orders

Batch orders cost less per-order on both Spot and Futures. Up to 15 orders per batch on Spot.

Read the suggestion field

When a rate limit error is returned, the suggestion field contains the specific limit that was hit and concrete advice. Parse it and adapt:

bash
RESULT=$(kraken balance -o json 2>/dev/null)
if [ $? -ne 0 ]; then
  CATEGORY=$(echo "$RESULT" | jq -r '.error // "unknown"')
  if [ "$CATEGORY" = "rate_limit" ]; then
    SUGGESTION=$(echo "$RESULT" | jq -r '.suggestion // "Wait and retry"')
    DOCS=$(echo "$RESULT" | jq -r '.docs_url // ""')
    echo "Rate limited. $SUGGESTION"
    echo "Read more: $DOCS"
  fi
fi
Multi-command budget planning

Before executing a sequence, estimate total cost:

bash
# This sequence costs ~5 points on the Spot REST counter:
kraken ticker BTCUSD -o json 2>/dev/null       # 1 point
kraken balance -o json 2>/dev/null             # 1 point
kraken open-orders -o json 2>/dev/null         # 1 point
kraken trades-history -o json 2>/dev/null      # 2 points (heavy call)

Leave headroom for retries and unexpected calls.

If you hit a mismatch between what you are trying to do and the CLI's interface or responses — including a mismatch between this skill and the installed CLI version's contract — feel free to submit feedback with kraken feedback.
