How this service works
DEMO/synthetic endpoint: returns deterministic pseudo-prices for top assets to test the x402 wire format. NOT live market data — use token-price / token-momentum for real prices. Paid via x402: $0.001 in USDC on Base (eip155:8453) to 0x973a31858f4d2125f48c880542da11a2796f12d6. Returns 402 with payment requirements; pay and retry.
Output
A deterministic set of pseudo-prices for top crypto assets (e.g. BTC, ETH). Data is synthetic and fixed — not live market data. The response confirms the x402 payment wire format is working. Preceded by a 402 response containing payment requirements (0.001 USDC on Base to the specified address); after payment, retrying yields the snapshot payload.
Example use cases
Example prompt
“Hit the x402 Bazaar market snapshot demo endpoint and walk me through the 402-pay-and-retry flow — I want to confirm my x402 USDC payment on Base goes through and get back the deterministic pseudo-prices it returns.”
Technical details
Endpoint
POSThttps://api.relai.fi/relay/1782567677091/api/x402/market-snapshotWhen to prefer
Use this endpoint when you need to test or demonstrate the x402 micropayment wire format end-to-end without relying on live market data. Ideal for integration testing of x402 client libraries, payment middleware, or agent payment flows at minimal cost ($0.001 USDC). Do NOT use for real asset prices — use token-price or token-momentum endpoints instead.
Side effects
- 402 returned before payment — expected behavior; client must attach payment header and retry
- Insufficient USDC balance on Base — payment rejected, 402 persists
- Wrong chain (not eip155:8453 / Base) — payment not recognized
- Malformed x402 payment header — endpoint rejects with 402 or 400
- Network unavailability on api.relai.fi — connection timeout or 5xx
