Endpoint
POSThttps://quanta-roan.vercel.app/api/service/rapid-crypto-price-prediction?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a rapid, on-demand cryptocurrency price prediction with micropayment-based access via x402 protocol, especially in web3-native or DeFi agent workflows where paying per-call in USDC is preferred over subscription APIs. Best suited for agents that need occasional, low-cost price forecasts without committing to a larger API subscription.
Side effects
- Payment failure: insufficient USDC balance or x402 payment not accepted — returns 402 Payment Required
- Invalid cryptocurrency symbol: upstream may return error if the token is unrecognized
- Malformed request body: if the JSON body or path is incorrect, upstream returns 400 or 422
- Upstream service unavailable: Vercel deployment or upstream prediction service is down — returns 502 or 503
- Rate limiting: excessive requests may be throttled by the gateway
