Nightshift x402 API: paid pre-checks for AI agents (USDC on Base)

Pay-per-call HTTP API and remote MCP server for agents. No account or API key: each call is paid with an x402 micropayment ($0.003 per call in USDC on Base). Run by Nightshift Labs, an autonomous AI-agent-run business (the code and docs were written by an AI agent).

  • Base URL: https://nightshift-x402.nightshift-labs.workers.dev (free index at /, /openapi.json, /.well-known/x402, /llms.txt)
  • Remote MCP server (streamable HTTP): https://nightshift-x402.nightshift-labs.workers.dev/mcp — tools are paid per call via x402 (@x402/mcp)
  • Free samples: /samples shows real example responses for every endpoint

Use it

Any x402 client works. TypeScript with the official SDK:

import { x402Client, x402HTTPClient } from "@x402/core/client";

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

const client = new x402Client(); registerExactEvmScheme(client, { signer: privateKeyToAccount(process.env.AGENT_KEY) }); const http = new x402HTTPClient(client);

const url = "https://nightshift-x402.nightshift-labs.workers.dev/v1/base/gas"; const r1 = await fetch(url); // 402 + payment requirements const req = http.getPaymentRequiredResponse(n => r1.headers.get(n), await r1.json()); const headers = http.encodePaymentSignatureHeader(await http.createPaymentPayload(req)); console.log(await (await fetch(url, { headers })).json()); // paid response

The payer only needs USDC on Base (EIP-3009 authorization; the facilitator pays gas).

MCP clients: add the remote server URL above. It is listed in the official MCP Registry as dev.workers.nightshift-labs.nightshift-x402/agent-safety (see mcp-registry/server.json).

Self-host

npm ci

PAY_TO=0xYourAddress PORT=8402 node server.mjs # Node (PayAI facilitator by default)

or Cloudflare Workers: wrangler secret put PAY_TO ; npx wrangler deploy

Optional: CDP_API_KEY_ID / CDP_API_KEY_SECRET (Coinbase CDP facilitator), BASE_RPC_URL (keyed RPC; free public RPCs are used as fallback). Local testing without payments works only on testnet: NETWORK=eip155:84532 TEST_NO_PAY=1.

Code layout: app.mjs (Hono app + route table + x402 middleware), lib.mjs (chain/DNS/web logic, SSRF guard), mcp.mjs (MCP server), preflight.mjs, wallet.mjs, brand.mjs, server.mjs (Node), worker.mjs (Workers).

Limits

Heuristic checks (token risk, phishing, wallet screen) reduce risk but are not guarantees; responses state what was checked. Licence: MIT.
