Technical details
Endpoint
GEThttps://x402-api-production-bd43.up.railway.app/ath?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need the historical all-time high price for a specific cryptocurrency. Prefer it over general price APIs when the user explicitly asks about peak/record prices rather than current or historical time-series data. It is a paid microtransaction endpoint ($0.01 USDC via x402), so it suits agents with cryptocurrency payment capability.
Side effects
- Invalid or unrecognized coin ID returns an error or empty result
- Network or server downtime on Railway hosting causes unavailability
- Payment failure (insufficient USDC balance or x402 protocol error) blocks the request
- Rate limiting or abuse detection may temporarily block repeated calls
