Technical details
Endpoint
POSThttps://quanta-roan.vercel.app/api/service/rapid-crypto-news51?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need pay-per-use cryptocurrency news retrieval without a subscription, particularly in Web3/DeFi agent contexts that already handle x402 micropayments in USDC. It is ideal for low-frequency news polling where a $0.01 per-call cost model is acceptable and you want to avoid API key management overhead.
Side effects
- Payment failure: insufficient USDC balance or x402 payment header missing/malformed results in 402 Payment Required
- Upstream unavailable: the proxied news source is down or rate-limited, returning an error passthrough
- Invalid path or query: malformed path or query parameters may return an upstream 404 or 400 error
- Network timeout: Vercel serverless cold start or upstream latency may cause timeouts
- Schema mismatch: sending unexpected body fields may be silently ignored or cause upstream errors
