Technical details
Endpoint
GEThttps://x402.professorsausages.com/prices/history/:pairWhen to prefer
Choose this endpoint when you need historical Chainlink oracle price round data (getRoundData) for a specific crypto trading pair, particularly for DeFi analytics, backtesting, or on-chain price verification. Prefer this over spot-price endpoints when you need multiple historical rounds rather than a single current price, and when Chainlink's oracle provenance and immutability are important.
Side effects
- Unsupported or invalid trading pair returns an error or empty result
- Pair format mismatch (e.g. wrong delimiter or casing) may cause 404 or bad request
- Rate limiting or payment failure due to x402 micropayment not going through
- Chainlink feed unavailable for the requested pair on the supported chain
- Cache staleness up to 1 hour may mean data is not real-time current
