Technical details
Endpoint
GEThttps://api.hyperextend.xyz/v1/outcome_ctx/%231000When to prefer
Use this endpoint when you need outcome-specific market context for a HIP-4 prediction market coin, specifically mark/mid price and circulating supply alongside volume, and you have the encoded outcome-side coin identifier (e.g. #1000). Prefer this over the main market context endpoint when you need outcome-side granularity rather than aggregate open interest or funding rate data.
Side effects
- Invalid or malformed coin identifier (e.g. not in '#<10*outcome+side>' format) returns an error
- Start or end timestamp outside available data range may return empty results
- Limit parameter too large may be capped or rejected
- Payment not included or insufficient USDC balance causes 402 Payment Required
- Coin identifier for a non-existent outcome returns 404 or empty response
