How this service works
Pay-per-request crypto market data API for AI agents. 16 endpoints on Base Mainnet via x402 protocol. No accounts, no API keys. USDC micropayments from $0.001. Works with Claude Desktop, ElizaOS, and any MCP client.

A JSON object containing a 'data' field with historical market data records (OHLCV or price series) for the specified trading pair, interval, and limit, plus a 'success' boolean confirmation.
Example use cases
Analyze crypto volatility for trading signals
“Fetch the last 200 daily candles for ETH-USDC and analyze the price volatility over the past year. Use my USDC balance on Base to pay for the data, then tell me if there's a pattern I should watch.”
Compare multi-pair price movements
“Pull hourly OHLCV data for the last 72 candles on SOL-USDC, BTC-USDC, and AVAX-USDC. Pay with USDC from my Base wallet and show me which pair has been most volatile this week.”
Monitor historical support and resistance levels
“Get me the last 500 4-hour candles for Ethereum so I can identify key support and resistance levels. Charge my Base USDC account for the data retrieval and highlight any price zones that have held strong over the past 3 months.”
Technical details
Endpoint
GEThttps://agentdata-api.com/api/historicalWhen to prefer
Use this endpoint when an AI agent needs historical candlestick or price data for a cryptocurrency trading pair without registering an account or managing API keys, and can pay per-request in USDC via the x402 protocol on Base Mainnet. Ideal for autonomous agents running in Claude Desktop, ElizaOS, or MCP environments that need on-demand crypto history for analysis or strategy.
