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
Returns a JSON object containing an array of [timestamp, price] pairs covering the requested time window (default 30 days), plus the 'days' field confirming the window used. Timestamps are Unix milliseconds; prices are in USD.
Example use cases

Crypto trend analysis for trading bot

Year-over-year price comparison
“Pull the 365-day historical price data for bitcoin so I can compare where it was this time last year versus now.”

Endpoint
GEThttps://three.ws/api/x402/market-chart?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need lightweight, pay-per-call historical cryptocurrency price data billed in USDC micropayments via the x402 protocol, especially within an agent workflow that already operates on the three.ws platform or needs to avoid subscription-based data providers.
Side effects
- Invalid or unrecognized CoinGecko coin ID returns an error or empty data
- Invalid 'days' value (not in 1/7/30/90/365) may return an error or fall back to default
- Missing required 'id' query parameter returns a 400-level error
- Payment not processed (x402 micropayment failure) results in 402 response blocking data access
- Rate limiting or upstream CoinGecko unavailability may cause 5xx errors
