# Invoket — Pre-Action Checks for AI Agents > The checks agents run before they act: ask one question about the real world, get the answer from the source of record, with its provenance attached. You only pay for answers. Invoket is one x402 interface to the checks an AI agent runs before it acts — before it pays, signs, ships, publishes or advises. Each endpoint answers a single question about the real world, and answers it from the official source of record: public registers, regulators, and official national or EU datasets, not a third-party aggregator. Every response carries a provenance block — source, fetch time, freshness — so an agent can decide how far to trust it before acting on it. The inventory lives where it cannot go stale: GET /catalog lists every endpoint with its price and its input and output schemas. Most single-call endpoints include one free call per day, on request: send `X-402-Trial: 1` on the call and on the signed retry. You only pay for answers: no usable result, no charge. Invoket is an x402 payment gateway that monetizes microservices for autonomous AI agents (machine-to-machine). Each endpoint answers 402 Payment Required with an `accepts[]` array of payment options; sign one and re-submit it via the `PAYMENT-SIGNATURE` header. You are only charged on success — probing an endpoint never charges. A settled success returns a `PAYMENT-RESPONSE` header; a 2xx response that carries no usable result is not charged and returns no `PAYMENT-RESPONSE`, which you can verify mechanically. GET endpoints also accept POST with a flat JSON body mirroring the query parameters; a parameter already present in the URL query takes precedence over the body. Found a gap, a bug, or a missing case? Send structured feedback (no payment required) via POST /review. Official MCP server: run `npx -y @invoket/mcp` to expose every endpoint as a typed, auto-paying MCP tool (bring your own wallet key; it never leaves your machine, never sent to us). Docs:
