How this service works
63 paid API endpoints protected by x402 micropayments on Base
Output
A JSON object with a 'data' field containing the structured response from whichever of the 63 upstream paid APIs the hub determined best matched the input query. The exact shape of 'data' varies by upstream service.
Example use cases
Real-time crypto price lookup
“Query the X402 Hub copilot with 'What is the current ETH/USD price?' so I can get the latest Ethereum price routed to the right paid data source.”
Weather data via paid API gateway
“Ask the X402 Hub copilot 'What is the weather forecast for San Francisco this weekend?' and get back the structured forecast from whichever upstream API the hub selects.”
Company financial data retrieval
“Send the X402 Hub copilot the query 'What was Apple's revenue in Q4 2023?' and return the financial data from the appropriate paid endpoint it routes to.”
Technical details
Endpoint
POSThttps://x402-hub.vercel.app/api/copilot?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to query one of a broad set of curated paid data APIs using natural language without knowing which specific API to call — it acts as a smart router and proxy. Prefer it over calling individual APIs directly when you want to avoid managing multiple API keys, x402 payment headers per-service, or endpoint discovery. Best suited for exploratory queries where the exact upstream data source is less important than getting a relevant answer quickly.
Side effects
- Query too ambiguous to route to a specific upstream endpoint — returns empty or error response
- Upstream API temporarily unavailable — hub may return a 502 or partial response
- Insufficient USDC balance to cover $0.125 micropayment — x402 payment fails and request is rejected
- Query falls outside scope of all 63 available endpoints — no matching upstream found
- Malformed query string causes routing failure — returns 400 bad request
- Rate limits on upstream APIs exceeded — hub returns throttling error
