The Details

MintAPI is my x402 API project for agent-ready paid access to structured external-platform data.

It combines a seller-side gateway, buyer SDK, public docs, and agent integration patterns so teams can call paid endpoints without pushing payment logic into prompts or fragile custom glue code.

Why It Matters

Most paid APIs are optimized for humans with dashboards and long-lived API keys. MintAPI also supports agent and backend workflows where the runtime should detect a 402 Payment Required challenge, settle the request, and retry automatically.

That makes it a better fit for:

  • AI agents that need request-based API payments
  • backend automations that should pay only when they execute
  • product teams that want one API layer across multiple platforms
  • developer tooling that needs predictable, structured JSON

The Features

  • x402 payment flow for agent and runtime-based buyers
  • API-key access for human users and dashboards
  • Structured endpoint coverage across X, YouTube, TikTok, Instagram, Yelp, and Facebook
  • Buyer SDK helpers for paidFetch, paidJson, and createAgentClient(...)
  • OpenClaw plugin support for native paid tools
  • Public docs and route discovery for implementation clarity
