Describe a task (or name a slug) and the Smart Order Router resolves the best-matching tool and RUNS it in the same call - flat $0.05 covering any tool listed at $0.04 or less, from THIS host's catalog or any external seller in the open index - x402 sellers, or MPP sellers on Tempo (paid on your behalf over x402 or MPP, result relayed). One payment, one request, result + receipt. /api/route quotes which tier a task needs; pricier tools return a self-correcting 409 with their direct route.

Live cross-provider x402 market sentiment. topProviders: the top x402 sellers ecosystem-wide, ranked by REAL on-chain activity (Agent402 included and flagged isSelf:true).

Every row carries all metrics plus callsPerBuyer (intensity), so revenue and actual ecosystem usage are both visible.

Infer a draft-07 JSON Schema from sample JSON document(s)
Infer a draft-07 JSON Schema from sample JSON document(s). Send one sample as json, or several as samples. Heuristic merge rules: required = keys present in every sample, conflicting types become a type union, integer widens to number, and string formats (date-time, date, email, uri, uuid) are detected from values. Complements json-validate.
