# three.ws Market Coins — Cryptocurrency Market Table

> three.ws Market Coins — Cryptocurrency Market Table is a paid API for AI agents from three.ws, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-23).

Returns a paginated, ranked table of cryptocurrency market data (price, market cap, 24h/7d change, volume, sparkline) from CoinGecko, optionally filtered by sector category or resolved by name/ticker search.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability three-ws-market-coins-cryptocurrency-market-table-c2c666ad
```

Example prompt: Show me the top 50 cryptocurrencies by market cap, filtered to the artificial-intelligence category, and include their 24-hour and 7-day price changes.

## When to prefer this

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.

## Known failure modes

- 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

## 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.
