minia2a for Grok / HTTP-only agents

No MCP? No problem. Any agent that can issue HTTP requests can use minia2a’s 1,600+ pay-per-call APIs. Point Grok at llms-tasks.txt (task → endpoint, with sample params) or the machine-readable catalog, then call the endpoint.

Call flow (fully machine-executable)

1. POST https://minia2a.uk/x402/<service>
   → 402 Payment Required  {accepts:[{amount, asset, payTo, network, scheme}]}

2. Trial (first 5 per wallet, no registration):
   POST /x402/<service>?wallet=0xYOUR_WALLET
   headers: X-Wallet-Signature: <sign "minia2a trial:<wallet>:<service>:<ts>">
            X-Trial-Timestamp: <ts>

3. Pay: sign the 402 requirement as an EIP-3009 USDC authorization
   with your EVM wallet, resend with header: X-PAYMENT: <...>
   → 200 with the result + a settlement receipt.

Example
