How this service works
Every request, a quantum of value. x402 protocol-based payment endpoint for web3/DeFi tools.
Output
The raw upstream response from the Rapid Crypto Screener API is passed through after successful $0.01 USDC x402 micropayment — typically JSON containing token screening results, market metrics, rankings, scores, or other cryptocurrency data depending on the query path and parameters supplied.
Example use cases
Screen top momentum crypto tokens
“Use the rapid crypto screener to show me the top 10 tokens ranked by momentum right now — I want their tickers, prices, and screening scores.”
Check DeFi token market signals
“Fetch the rapid crypto screener data for AAVE and UNI — give me their current market signals and any bullish or bearish indicators.”
Find trending low-cap crypto assets
“Run a crypto screen for low-cap altcoins showing unusual volume or price action today — I want whatever the rapid crypto screener surfaces as trending.”

Endpoint
POSThttps://quanta-roan.vercel.app/api/service/rapid-crypto-screener-official-api?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need pay-per-call access to the Rapid Crypto Screener API without committing to a subscription, or when operating in a web3/crypto-native agent context where x402 USDC micropayments are already supported. Ideal for infrequent or burst queries where per-request $0.01 pricing is more economical than a flat subscription.
Side effects
- Payment failure — insufficient USDC balance or x402 payment not accepted, returns 402 Payment Required
- Upstream API error — the Rapid Crypto Screener service is down or returns an error code
- Invalid path — requested API sub-path does not exist on the upstream service
- Malformed request body — JSON body is invalid or missing required upstream parameters
- Rate limiting — upstream API enforces its own rate limits beyond the payment gateway
