How this service works
Paid cryptocurrency API endpoints via x402 micropayments
Output
A JSON object with a 'data' field containing the response payload from the upstream cryptocurrency API, including a list of matching crypto assets. The exact structure of each asset entry may vary depending on the query and path used.
Example use cases
Browse top crypto assets
“Give me a list of the top 50 cryptocurrencies available — search for anything matching 'bitcoin' and start from the beginning of the list.”
Paginate through crypto catalog
“I want to browse through the full crypto asset catalog in batches — fetch 25 results starting from offset 100 using the crypto list search.”
Search DeFi tokens
“Can you search the crypto list for tokens related to 'defi' and return the first 30 results?”
Technical details
Endpoint
POSThttps://x402-crypto.vercel.app/api/crypto-list/%7Bpath%7DWhen to prefer
Use this endpoint when you need to search or browse a cryptocurrency asset catalog programmatically and are willing to pay a per-call micropayment via the x402 protocol. Prefer this over free crypto APIs when operating in an x402-native agent workflow where automatic micropayments are already wired up. Best suited for lightweight listing and search queries rather than deep market data or real-time price feeds.
Side effects
- Payment failure if the x402 micropayment of $0.071916 USDC is not successfully submitted
- Empty results if the query string matches no known cryptocurrency assets
- Invalid offset or limit values causing pagination errors
- Path parameter not resolved if {path} template is not substituted correctly
- Upstream API unavailability causing 5xx errors
