Developer Search

Search developer sources in one call: Hacker News stories (Algolia), GitHub repositories (by stars), npm packages (with weekly downloads), PyPI (exact package lookup, PyPI has no search API) and Stack Overflow questions. Each source returns its own list; a source that is rate limited reports an error without failing the call. Params: query (required), sources (default all: hackernews, github, npm, pypi, stackoverflow), limit per source (1 to 20, default 5).

Call it

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

const client = new x402Client();
registerExactEvmScheme(client, { signer: privateKeyToAccount(process.env.EVM_PRIVATE_KEY) });
const payFetch = wrapFetchWithPayment(fetch, client);

const res = await payFetch("https://agentsvc.io/api/v1/proxy/dev-search", {
  method: "POST",
  headers: { "Content-Type": "application/json" },
  body: JSON.stringify({"query":"x402","limit":3}),
});
const { data, payment } = await res.json();  // payment.transaction = on-chain receipt
