Create a temporary public webhook endpoint for AI agents and automated workflows that need to receive asynchronous callbacks from external services. Returns a callback URL plus read and wait endpoints. No server deployment, signup, API key, or subscription required.

Decode EVM smart-contract transaction calldata into the function name and typed parameters. Supply an ABI (from /api/contract-abi) or a signature like transfer(address,uint256) for a fully offline decode; with neither, the 4-byte selector is resolved via the openchain.xyz signature database (4byte.directory fallback) and each candidate signature is tried. Unknown selectors return a documented partial decode (selector + raw 32-byte words) instead of an error.

CANTU Buyer Demand Search — Paid machine-readable search for current buyer demand and procurement opportunities; also verifies a specific official notice ID or URL.

Calculate reproducible capability performance from versioned evidence-bound cases

Computes weighted pass rates and weighted scores from caller-labeled test outcomes, with deterministic category summaries. It does not run tests, validate labels, measure untested capabilities or establish deployment safety; the result is only as representative as the supplied evaluation set.

Compare required and offered agent capabilities before execution

Compare claimed capabilities with independently evidenced successful observations

Hospital capital-expenditure jump signals from CMS cost reports (Worksheet A-7): hospitals whose major movable equipment purchases hit at least $1M and at least 2x the prior fiscal year — an observational marker that a hospital reported a step-up in equipment spend. Answers: which hospitals just bought equipment? Includes purchase dollars by asset class and the prior-year comparison. Filter by state, min_amount (movable-equipment dollars), since; keyset cursor pagination.

Capped observer-backed gateway over five allowlisted proven sellers; pays selected upstream from a small float, adds a transparent 10% margin, and returns payment reference, delivery and gateway receipt

Classifies captcha type (reCAPTCHA, hCaptcha, Turnstile) and difficulty. Eval only — we do NOT solve captchas.
