How this service works
Paid cryptocurrency API endpoints via x402 micropayments
Output
Returns a data object containing a list of cryptocurrency assets matching the filter query, sorted and limited per the request parameters, including relevant market metrics such as market cap and volume for each result.
Example use cases
Finding large-cap crypto investments
“Give me a list of the top 25 cryptocurrencies sorted by market cap in descending order, filtering for coins with market cap over 5 billion.”
Discovering high-volume altcoins
“Screen crypto tokens with volume over 100 million, sort them by volume descending, and return the top 10 results so I can spot which altcoins are getting the most trading action right now.”
Hunting small-cap opportunities
“Find me the top 30 small-cap cryptocurrencies sorted by market cap ascending — I want to see coins with market cap less than 100M to look for emerging projects.”
Technical details
Endpoint
POSThttps://x402-crypto.vercel.app/api/screener-official/%7Bpath%7DWhen to prefer
Choose this endpoint when you need to programmatically screen and filter the cryptocurrency market by quantitative criteria (market cap, volume thresholds) and retrieve ranked lists of tokens. Prefer this over general market data endpoints when you need flexible query-based filtering with custom sort order and result limits. Best suited for agents that need to pay per-call via x402 USDC micropayments without a subscription.
Side effects
- Payment failure if insufficient USDC balance for x402 micropayment ($0.084958 per call)
- Invalid query syntax returns error or empty results
- Unsupported sort field name causes malformed request
- Missing required 'query' field results in validation error
- Upstream crypto data provider unavailability causes 502/503
