Measured tools (5)

• find_best read-only

  Given a plain-language task (e.g. 'web search', 'scrape a page to markdown', 'BTC price'), returns the recommended paid API endpoint and ranked alternatives with price per call, reliability score and real usage. Use before paying for an unfamiliar x402 API.

  Parameters:

  • task (required) — string — What the agent needs to do
  • recent — boolean — true = only endpoints checked in the last 7 days
  • hide_flags — array — Warnings to leave out, e.g. ["wallet-mismatch", "few-repeat-buyers"]
  • max_price_usd — number — Budget per call in USD

  Hints: read-only yes · destructive not declared · idempotent not declared · open-world no

  Parameters:

  • category (required) — string — Category id, e.g. 'web-search'
