Endpoint
GEThttps://x402-stock-indicators.vercel.app/crypto-history/%7Bsymbol%7DWhen to prefer
Choose this endpoint when you need 30-day historical crypto price, volume, and market cap data with no API key or subscription required — ideal for agents that need lightweight, pay-as-you-go access via USDC micropayments over the x402 protocol, especially in automated or low-frequency workflows where traditional API subscriptions are overkill.
Side effects
- Invalid or unrecognized symbol returns an error or empty data
- Payment failure (insufficient USDC balance or unsupported chain) blocks the request
- CoinGecko upstream outage may cause 502 or stale data
- Malformed symbol in URL path returns 400 or 404
- Rate limiting on upstream data provider may delay response
