How this service works
Make a 3D AI agent from a selfie in 60 seconds. Drop one HTML tag to embed it on any website. Agents think on IBM watsonx.ai (Granite); optionally charge per chat with built-in micropayments.
Output
A JSON object containing the current page number, the chosen category (or null), rows-per-page setting, and an array of coin objects each with: CoinGecko id, name, ticker symbol, global rank, current USD price, 24h and 7d percentage changes, market cap, 24h volume, and a sparkline array of recent price points.
Example use cases
AI sector token market overview
“Pull up the top coins in the artificial-intelligence crypto category — I want to see their prices, market caps, and how they've performed over the last 7 days.”
Resolve ticker to CoinGecko ID
“I need the CoinGecko coin id for 'ETH' — can you look that up so I can use it in another API call?”
Paginated crypto leaderboard
“Give me page 2 of the crypto market rankings, 50 coins per page, so I can see what's ranked 51 through 100 right now.”

Endpoint
GEThttps://three.ws/api/x402/market-coins?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a structured, paginated cryptocurrency market table with sparklines and sector filtering backed by CoinGecko data and accessible via x402 micropayment — ideal for agents that need programmatic crypto rankings without managing a full CoinGecko API key, or when you want to scope results to a specific market sector like AI tokens or DeFi.
Side effects
- Invalid page number outside 1–20 returns an error or empty result
- per_page value outside 10–250 is rejected
- Unknown category id returns empty or error response
- Search query with no matches returns empty coins array
- Rate limiting or payment failure ($0.001 USDC) blocks access
- Stale data if CoinGecko upstream is slow or unavailable
