What it does

Capacitr is an agent skill from BankrBot/skills. Paste a URL or free text and get matched Polymarket / Hyperliquid / Deribit markets with Quotient edge scores. Pay in $CAPACITR over x402 on Base — real on-chain settlement via Coinbase facilitator (or USDC fallback when the agent's wallet doesn't hold $CAPACITR). Single paid endpoint, no signup, no skill key. Triggers: "analyze this link", "what's the trade here", "find markets for X", "research X on Polymarket".

Its SKILL.md is about 3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 8 other files, including scripts and reference files (for example `catalog.json`, `references/api-reference.md` and `references/error-handling.md`).

It sits in Backend & APIs, covering Smart contracts. It works with Coinbase, Polymarket, Circle USDC and x402. The repository describes itself as: Bankr Skills equip builders with plug-and-play tools to build more powerful agents.

When your agent uses it

  • Tasks that involve Smart contracts

Example prompts

  • “s wallet doesn”
  • “analyze this link”
  • “s the trade here”
  • “/capacitr”

Requirements

  • A Bash shell

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

  1. POST without X-Payment. Expect 402 with x402.accepts[].
  2. Prefer the accepts[] entry where extra.symbol === "capacitr".
  3. Read accepts[].extra.assetTransferMethod to know which signing
  4. Retry with X-Payment: header → 200 + payload.

What it can do on your machine

Read from SKILL.md and the folder at commit dc47eed. 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

    Ships 2 files in scripts/ (Shell), which the agent can run.

    Shell commands in SKILL.md call:

    • jq
    • curl

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

  • Network

    Links to these hosts (documentation or services it may open):

    • basescan.org

    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

Capacitr loads about 3k tokens when it runs, and up to ~6.3k if it reads all its reference files. Until then it costs about 108 tokens; SKILL.md has 662 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~108
When it runs · the whole SKILL.md, loaded when a task matches
~3k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~6.3k

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); the scripts in this folder are not scanned.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 662 words (~3,015 tokens).

“Market discovery as a single x402-paid HTTP call. Paste a URL or sentence; get back ranked Polymarket / Hyperliquid / Deribit markets with Quotient intelligence (fair odds, spread, BLUF) overlaid. One endpoint, one payment, one response.”
