Technical details
Endpoint
POSThttps://api.relai.fi/relay/1769629274857/x402/bitquery/tokenchartWhen to prefer
Use this endpoint when you need historical price and timestamp data for a specific token on a supported EVM chain (Base, Ethereum, BSC, Arbitrum, Polygon, Optimism, zkSync) and want to chart or analyze price movement over a defined period (1h, 4h, 24h, 7d, 30d). It is ideal for DeFi dashboards, trading bots, or portfolio trackers needing on-chain token price history rather than spot price alone.
Side effects
- Missing tokenAddress parameter returns a 400 or validation error
- Invalid or non-existent contract address returns empty data or error
- Unsupported chain specified returns an error or falls back to Base
- Payment of $1 USDC not provided causes a 402 Payment Required response
- Network or BitQuery upstream outage causes timeout or 503 error
