The endpoint quotes itself

Start with a normal HTTP request. The 402 response includes the exact price, Base network, USDC contract, receiver, and Bazaar discovery metadata for the endpoint.

curl -i "https://scrappa.co/api/maps/autocomplete?q=bakery"

# HTTP/2 402
# PAYMENT-REQUIRED: eyJ4NDAyVmVyc2lvbiI6Mi...

Protocol flow

Same request, normal JSON

x402-compatible clients automate the quote, signature, and retry loop. Scrappa returns the same parameters and response shape as API-key authentication.

1. Call any Scrappa API endpoint without authentication.
2. Read the 402 response and its PAYMENT-REQUIRED header.
3. Sign the quoted USDC authorization on Base.
4. Retry with PAYMENT-SIGNATURE and receive the normal JSON response.

Built for autonomous callers

Discoverable without a dashboard
