Technical details
Endpoint
GEThttps://cryptofeed402.site/history?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need historical crypto market context over a range of days — especially for backtesting strategies based on sentiment or funding rates, building time-series narratives, or reviewing how market conditions evolved around specific events. Prefer this over the live/current brief endpoint when the user's need is retrospective rather than real-time.
Side effects
- Missing required 'from' date parameter returns a validation error
- Date range exceeding 366 days may be rejected or capped
- Invalid date format (not YYYY-MM-DD) returns a schema validation error
- Dates with no published briefs return an empty briefs array
- Payment failure on Base network blocks access (x402 payment required)
- Future dates or very recent dates may have no data if briefs not yet generated
