How this service works
63 paid API endpoints protected by x402 micropayments on Base
Output
A JSON object containing a 'data' field with the upstream Coinbase API response, which varies depending on the query submitted. The shape of the data object is determined by which of the 63 underlying Coinbase endpoints is invoked.
Example use cases
Real-time crypto price lookup
“Can you check the current Ethereum price in USD using the Coinbase x402 Hub? Go ahead and pay the micropayment if needed.”
On-chain Base network data fetch
“I need to pull the latest Base network transaction data from the Coinbase x402 Hub — my query is 'latest_transactions' — please handle the x402 payment and return what comes back.”
Portfolio enrichment with Coinbase data
“Fetch Coinbase exchange data for my portfolio coins — query 'supported_assets' on the x402 Hub and show me the full list the API returns.”
Technical details
Endpoint
POSThttps://x402-hub.vercel.app/api/coinbaseWhen to prefer
Choose this endpoint when you need pay-per-call access to Coinbase data without a long-term API subscription, when your agent wallet supports x402 micropayments on Base, and when you want to query any of the 63 Coinbase API surfaces (market data, account info, asset lists, etc.) through a single unified gateway. Prefer alternatives if you have a native Coinbase API key, need bulk/batch queries cheaply, or require a specific Coinbase endpoint with a richer schema.
Side effects
- Payment failure: insufficient USDC balance causes 402 Payment Required response
- Invalid query: unrecognized query parameter returns error or empty data object
- Rate limiting: too many rapid calls may result in throttling from the upstream Coinbase API
- Network error: Vercel cold start or upstream Coinbase API downtime causes timeout or 5xx
- Malformed input: missing required 'query' field returns validation error
