How this service works
DEMO/synthetic endpoint mirroring the canonical x402 `/weather` example for wire-format testing. Output is deterministic from the city name — NOT real weather. Paid via x402: $0.001 in USDC on Base (eip155:8453) to 0x973a31858f4d2125f48c880542da11a2796f12d6. Returns 402 with payment requirements; pay and retry.
Output
A deterministic (non-real) weather response for the submitted city name, returned after completing an x402 micropayment of $0.001 USDC on Base (eip155:8453). Initially returns HTTP 402 with payment requirements; after payment, retries and returns the synthetic weather payload.
Example use cases
Validate x402 payment retry loop
“Can you hit the x402 Bazaar weather endpoint for 'New York', handle the 402 response, pay the USDC micropayment on Base, and then show me the full retry flow so I can confirm our x402 client is handling it correctly?”
Demo x402 micropayment wire format
“I need to demo the x402 HTTP payment protocol to my team — can you run a synthetic weather lookup for 'Tokyo' through the x402 Bazaar endpoint, pay with USDC on Base, and walk me through exactly what the 402 response and payment headers look like?”
Prototype x402-enabled API integration
“I'm building an x402-compatible client and want to make sure my payment header formatting is right — can you call the x402 Bazaar weather endpoint for 'London', complete the USDC micropayment on Base, and show me the raw request and response so I can compare against what my code produces?”
Technical details
Endpoint
POSThttps://api.relai.fi/relay/1782567677091/api/x402/weather?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to test or demonstrate the x402 HTTP payment protocol wire format, specifically the 402-then-retry flow with USDC micropayments on Base. Not for real weather data — output is fully synthetic and deterministic. Ideal for developers building x402-compatible clients or validating payment header formats.
Side effects
- HTTP 402 returned on first call — expected; must complete x402 payment and retry
- Invalid or missing city name may return an error or empty response
- Payment to wrong address or wrong chain (must be eip155:8453) will fail verification
- Insufficient USDC balance on Base will block payment completion
- Network issues with Base RPC may delay payment confirmation
