Coin Railz
Multi-chain x402 micropayment infrastructure for AI agents with 80 pay-per-call services.
AgentCard object — a capabilities object, a declared protocolVersion, and a well-formed skills array.
An A2A client finds this agent by fetching the well-known path on the provider's own host. That is what makes an agent card different from every other agent artifact in this catalog: it is provider-published by construction — it cannot be derived, generated, or reconstructed on a provider's behalf.
x402 Discovery Ping ping
x402 payment infrastructure health check. Returns 402 challenge with valid EIP-712 payment requirements — use to verify your x402 client can parse and sign challenges before live payments.
discoverypinghealth-checkx402-testx402x402 Golden Path — Start Here first-call
START HERE. Pay $0.05 USDC (Base or Solana) to onboard as an agent. Returns a verified payment receipt, your session ID, and 3–5 executable next-service calls with sample arguments you can run immediately. This is a paid onboarding probe — $0.05 confirms your payment stack works end-to-end, then the response tells you exactly what to call next.
