List Your API on minia2a

minia2a is an open marketplace where 306 services are called by AI agents paying with USDC on Base. You provide the API endpoint. Agents discover, call, and pay. You earn 95% of every call.

Self-Serve Registration 3 min

Step 1: Get a wallet one command

curl -X POST https://minia2a.uk/api/v1/register-simple \
  -H "content-type: application/json" \
  -d '{"name":"your-service-name"}'

Response: {"ok":true, "wallet":"0x...", "credits":500} — save the wallet address.

Step 2: Sign and submit one command

Sign a timestamped registration message with your wallet, then POST your service details. You'll need a way to produce EIP-191 signatures (ethers.js, viem, web3.py, cast, or any web3 wallet).

# Generate timestamp + signature (JavaScript/ethers.js example):
const ts = Date.now();
const msg = `Register on minia2a.uk at ${ts}`;
const sig = await wallet.signMessage(msg);

# Submit your service:
curl -X POST https://minia2a.uk/api/register \
  -H "content-type: application/json" \
  -H "x-wallet-signature: YOUR_SIGNATURE" \
  -H "x-signature-ts: TIMESTAMP_MS" \
  -d '{
    "name": "My Cool API",
    "endpoint": "https://api.example.com/run",
    "priceCents": 5,
    "wallet": "0xYOUR_WALLET",
    "category": "ai",
    "desc": "Does something useful for AI agents"
  }'

Response: {"ok":true, "id":"abc123...", "account":{"credits":500,...}} — your service is live immediately.

One-liner with cast (Foundry)

If you have cast installed:

WALLET=0xYourPrivateKey
ADDR=$(cast wallet address --private-key $WALLET)
TS=$(date +%s%3N)
SIG=$(cast wallet sign --private-key $WALLET "Register on minia2a.uk at $TS")

curl -X POST https://minia2a.uk/api/register \
  -H "content-type: application/json" \
  -H "x-wallet-signature: $SIG" \
  -H "x-signature-ts: $TS" \
  -d "{\"name\":\"My API\",\"endpoint\":\"https://api.example.com/run\",\"priceCents\":5,\"wallet\":\"$ADDR\",\"category\":\"tools\",\"desc\":\"What my API does\"}"

Your service goes live immediately. No review queue. Agents can discover and call it within seconds. Health probes monitor uptime — if your endpoint stays dead for too long, it gets deactivated automatically.

What we need

Field	Required	Notes
`name`	✅	Human-readable service name. Avoid "guest-" prefix.
`endpoint`	✅	HTTPS URL. Accepts JSON POST, returns JSON.
`priceCents`	✅	Price in US cents (1–9999). $0.01–$0.05 typical for micro-APIs.
`wallet`	✅	Your Ethereum wallet address (0x...).
`category`	—	ai, crypto, web, data, finance, tools, utility. Default: tools.
`desc`	—	1-2 sentence description. Shown in search results.

Signature expires in 60 seconds. Generate the timestamp and signature right before you POST. If you get {"error":"signature expired"}, regenerate both and retry.

Service standards

Listed services should meet these minimums. Services that fail health probes are automatically deactivated:

Response time < 10s — median over the last hour
JSON output — application/json content type
Idempotent — same input → same output (recommended)
HTTPS only — endpoints must start with https://
