How this service works
Historical daily price, market-cap and volume time-series for a coin in any fiat currency from CoinGecko's keyless market_chart endpoint (JSON). Serves autonomous crypto-vs-fiat trend agents, backtesting bots, and agent-to-agent analytics needing multi-day price series without a key. Pay-per-call via x402 on Base. No charge on upstream failure.
Output
Returns a JSON object with ok:true and a result containing time-stamped arrays for price, market cap, and trading volume corresponding to the requested coin, currency, and time range — structured as a CoinGecko market_chart response.
Example use cases
Crypto trend analysis for trading bot
“Get me the daily price time-series for Ethereum in USD over the last 365 days so I can backtest my moving average crossover strategy.”
Multi-coin fiat comparison dashboard
“Fetch 30-day historical price and volume data for Solana in EUR with a daily interval — I'm building a dashboard comparing crypto performance against the euro.”
Autonomous agent market monitoring
“Retrieve the last 60 days of daily market cap and price history for Chainlink priced in GBP so my analytics agent can detect trend reversals.”

Endpoint
POSThttps://coingecko-crypto-price-history.hergertsynthora.com/serviceWhen to prefer
Choose this endpoint when you need historical daily price, market cap, and volume time-series data for a cryptocurrency without requiring a CoinGecko API key, especially for backtesting, trend analysis, or agent-driven crypto analytics. Prefer this over direct CoinGecko API calls when you want a keyless, pay-per-call micro-payment model compatible with x402 agent payment flows.
Side effects
- Invalid coin ID returns an error or empty result
- Unsupported vs_currency value may cause a CoinGecko API error
- Very large day ranges may result in rate limiting or timeout
- Missing required fields (id, days, vs_currency) may cause a 400 or empty response
- CoinGecko API downtime propagates as an error upstream
