We run a handful of small x402 (HTTP 402) APIs on Base/USDC — a Lighter perp funding+wallet-scan feed, a USDC-tx verifier, an x402-endpoint linter, plus free dev checks (security headers, SPF/DKIM/DMARC, llms.txt, JWT). Pay-per-call, no subscription, no signup. Just shipped: an official MCP Registry listing and a tiny Node client (pay.mjs) that signs the 402 and retries for you. Everything's listed with real prices at doormat.sebastiaan-ba3.workers.dev — curious what else agent builders here wish existed as a paid API.
