Search US tax-exempt nonprofits (IRS Form 990 index) by name via the ProPublica Nonprofit Explorer API: EIN, name, city, state, NTEE code and total result count. Search results only; financial detail pages are not included. GuideStar itself has no free public API, so this uses ProPublica's index.

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://api.healthtravel-api.workers.dev/api/travel/guidestar", { method: "GET" });
console.log(await res.json());
