Technical details
Endpoint
POSThttps://api.arkm.com/x402/token/price-changeWhen to prefer
Choose this endpoint when you need a quick, point-in-time price change calculation for a specific token relative to a past timestamp, especially within an onchain intelligence or Arkham-native workflow. It is more targeted than fetching full historical OHLCV data and cheaper than endpoints that return full transfer or balance histories. Prefer it when the only required output is how much a token's price changed since a known moment.
Side effects
- Invalid or unrecognized CoinGecko token ID returns an error or empty result
- Malformed RFC3339 timestamp causes a validation error
- Timestamp too far in the past may exceed available historical data
- Payment failure (insufficient USDC balance) blocks the call
- Rate limiting or network timeouts on the Arkham API side
