Pyth price (latest)
POST /api/price-pythLatest aggregated price for one or more Pyth feeds, sourced live from Pyth's Hermes service. Use when you need an ORACLE-grade price with a published confidence interval (cross-checking an exchange feed, settling onchain logic); for a plain fiat quote crypto-price is simpler and cheaper. Identify feeds by hex feed-id (preferred - full precision) or by a small set of well-known aliases (BTCUSD, ETHUSD, SOLUSD, USDC, USDT). Each feed returns price, confidence interval, and publish-time so an agent can decide whether the quote is fresh enough to act on.
Input
| Field | Type | Description |
|---|---|---|
ids * | array | Pyth feed IDs (hex, with or without 0x) or known aliases (BTCUSD, ETHUSD, SOLUSD, USDC, USDT). 1-20 entries. |
