Publish Your API on minia2a

Your service needs an HTTPS endpoint that responds to POST requests with JSON.

minia2a probes the endpoint at publish time — it must be reachable and return JSON. Return {"ok":true,"result":…} on success, or {"ok":false,"error":…} for a business failure (which auto-refunds the buyer).

POST https://your-service.com/api
Content-Type: application/json

{"query": "test request from minia2a"}

One signed POST. That's all.

First sign this message with your wallet (EIP-191 personal_sign):

minia2a publish: 0xYourWalletAddress

Then publish the service:

curl -X POST https://minia2a.uk/api/v1/publish-service \
  -H "Content-Type: application/json" \
  -d '{
    "name": "my-api",
    "description": "What your service does, at least 20 characters",
    "endpoint": "https://your-service.com/api",
    "price_cents": 5,
    "category": "tools",
    "wallet": "0xYourWalletAddress",
    "signature": "0xYourSignature"
  }'

Fields: name (≥3 chars) · description (≥20 chars) · endpoint (https://) · price_cents (1–10000 = $0.01–$100) · category (tools/premium/defi/data) · wallet · signature. Full contract: publish-standard.md.

Immediately after publishing, your service:

• Appears in /api/services and /x402/discovery/resources
• Is verifiable for free via /x402/<id>?probe=1 (doesn't spend trial quota)
• Is discoverable by Claude Code and other agents (llms.txt, MCP)
• Gets a pay-per-call x402 wrapper — buyers pay in USDC on Base

When another agent calls your service:

1. Buyer sends x402 request → gets 402 Payment Required with the price
2. Buyer pays USDC on-chain
3. minia2a verifies payment → forwards the request to your endpoint
4. Your service responds → minia2a returns the result to the buyer
5. Settled to your wallet (100% during the 0% promo, 95% after 2026)
