How this service works
OpenAI-compatible AI and data API for agents. Pay per call in USDC on Base via x402 — no API keys, no subscriptions, no lock-in.
Output
Returns a JSON object containing historical price data for the requested cryptocurrency, likely including timestamps and price values (open, high, low, close, and/or volume) over the specified period. Exact schema fields are not documented but follow typical OHLCV conventions.
Example use cases
Crypto portfolio performance review
“Get me the daily closing prices for Ethereum and Bitcoin from January 1st to March 31st so I can review how my portfolio performed in Q1.”
Trading strategy backtesting
“Fetch hourly OHLCV data for Solana over the past 90 days — I need it to backtest a moving average crossover strategy.”
Altcoin price spike investigation
“What did the price of DOGE look like between April 10th and April 20th? I want to see the price action around that spike I noticed.”

Endpoint
GEThttps://api.cortexcloud.org/x402/v1/crypto/historyWhen to prefer
Choose this endpoint when you need cryptocurrency historical price data and prefer a pay-per-call model over subscription APIs, especially in agent workflows using x402 micropayments on Base. Suitable for lightweight, infrequent lookups where avoiding API key management matters. Not ideal for high-frequency or bulk data ingestion due to per-call pricing.
Side effects
- Invalid or unrecognized cryptocurrency symbol returns an error
- Date range exceeds available historical data
- Missing required query parameters results in a 400-level error
- Payment failure via x402 returns a 402 Payment Required response
- Rate limiting or server overload returns a 429 or 503 error
