40+ production APIs to test x402 payments against

[Robocular]

Production x402 test endpoints

I maintain an API gateway with 40+ services that all support x402 natively (USDC on Base). These could serve as test targets for the x402-openai-python client or as examples in documentation.

Test it

# Any of these return 402 with payment requirements (without payment)
curl -I https://agent-gateway-kappa.vercel.app/api/scraper/scrape
curl -I https://agent-gateway-kappa.vercel.app/api/screenshot/capture
curl -I https://agent-gateway-kappa.vercel.app/api/code/run

Available endpoints

40+ services including web scraping, screenshots, code execution (Python/JS/TS/Bash), web search, crypto prices, on-chain analytics, agent memory (vector search), file storage, PDF generation, image processing, and more.

All endpoints price: ~$0.002/request via x402 (USDC on Base)

Could be useful for the project's examples or integration tests!
