Forest Web

Validate one caller-supplied JSON request or response payload against the documented JSON schema for one exact OpenAPI or Swagger operation. Forest fetches only the supplied public specification, never invokes the described API operation, resolves only bounded local references, and reuses the same deterministic schema subset as json.validate.

This API is run by its own provider and paid directly through x402. We list it so you can find it; we don't route or hold the payment.

import { x402Client, wrapFetchWithPayment } from "@x402/fetch";
import { registerExactEvmScheme } from "@x402/evm/exact/client";

const client = new x402Client();
registerExactEvmScheme(client, { signer: agentAccount });

const pay = wrapFetchWithPayment(fetch, client);
const res = await pay("https://http--forest-gas-station-mainnet--lcjl27p8lmjs.code.run/openapi/payload-validate", { method: "POST" });
console.log(await res.json());
