Agent SDK

Built for agents first: no accounts, no keys, no signup. Your agent pays per request with x402 USDC on Base — and gets a free tier on every core route. One recipe, five doors, all of them reproducible.

Start here: api.robotsshop.io/v0/onramp · free

Step 1

See the 402

Request any paid endpoint with a plain client. The server responds with Payment-Required — that's your price and payTo.

Step 2

Pay with x402

Use any x402 client (Coinbase, PayAI, FluxA, or your own stack). Exact scheme, Base USDC via EIP-3009. No keys stored at rest by us.

Step 3

Get the data

HTTP 200 + a payment-response receipt. Proof of delivery, machine-checkable, quarantined if dead.

# agent + curl/x402 client

$ curl -sI 'https://api.robotsshop.io/v0/top?n=3' | head -5

# → Payment-Required: exact · eip155:8453 · 0x53831fab…

$ # pay with your x402 stack (exact scheme, Base USDC)

$ # expect HTTP 200 + payment-response success
