minia2a_get_stats

Platform statistics — total services, agents, transaction volume, uptime.

minia2a_register

Register with a self-custody wallet + EIP-191 signature — get 500 free credits to start. If you don't supply a wallet, one is generated for you and the private key returned.

minia2a_credits

Explain the V5 credit/trial model + platform stats. (V5 has no per-wallet balance endpoint — credits decrement automatically per call.)

minia2a_buy_credits

Claim credits from a completed USDC on-chain transfer by submitting your transaction hash.

minia2a_call_service

Call any x402 service with ?wallet=<your-wallet> (credits decrement) or anonymously (trial). Handles the HTTP 402 payment flow.

minia2a_check_endpoint ← NEW in v1.1.3

Validate any x402 endpoint for Claude Code auto-mode readiness (Aug 14, 2026). Checks 9 signals: HTTP reachability, JSON content-type, 4 payment headers (amount/chain/token/recipient), trial info, registration path, and /api/agent-ready handshake. Returns a scored report with per-check PASS/FAIL detail.

• 15 free trial calls shared globally — no wallet, no registration
• 500 free credits on registration — try any paid endpoint

{  "version": "1.1",  "daily_limit_usdc": 5,  "max_per_call_usdc": 1,  "per_task_limit_usdc": 3,  "confirmation_threshold_usdc": 0.5,  "idempotency_key": "required",  "verify_settlement": true,  "audit_trail": true}

What is x402?

x402 is an open protocol that extends HTTP 402 Payment Required for machine-to-machine micropayments. Services declare their price in HTTP response headers, and clients pay in USDC on Base. No intermediaries, no settlement delays. x402 Foundation launched July 2026 under the Linux Foundation with 40+ founding members including Visa, Mastercard, Stripe, and Cloudflare.
