API key required for POST /v1/price starting July 24, 2026

Starting July 24, 2026, POST /v1/price requires API-key authentication, and unauthenticated access to it will be disabled. Pass Authorization: Bearer <PRO_API_KEY>; API-key auth is supported today, so add the header now to stay forward-compatible. Do not expose the key in browser apps — keep it server-side. See Authentication for the header format and frontend-safe guidance, and the announcement for details.

Endpoints

Method	Path	Auth	Description
POST	`/v1/latest_price`	Yes	Fetch the latest price for one or more price feeds
POST	`/v1/price`	Yes (from July 24, 2026)	Fetch price data at a specific historical timestamp

POST /v1/latest_price

Returns the most recent price data for the requested feeds. The request body follows the same schema as the WebSocket subscribe message — see the Payload Reference for full details.

Request Body

Field	Type	Required	Description
`channel`	`string`	Yes	Subscription channel. One of: `real_time`, `fixed_rate@1ms`, `fixed_rate@50ms`, `fixed_rate@200ms`, `fixed_rate@1000ms`

Each feed has a minimum supported channel (min_channel), discoverable via /v1/symbols. You must use a channel at or above the feed's min_channel. See Symbology & Reference Data for every field the symbols endpoint returns.

POST /v1/price

Returns price data at a specific historical timestamp.

Request Body

All fields from /v1/latest_price, plus:

Field	Type	Required	Description
`timestamp`	`u64`	Yes	Unix timestamp in microseconds. Must be a raw integer — do not quote it.

For the full response schema — including price feed fields, signed payloads, and available properties — see the Payload Reference.

Authentication

Starting July 24, 2026, POST /v1/price requires API-key authentication, and unauthenticated access to it will be disabled. Pass your Pro API key as a bearer token:

curl -X POST -H "Authorization: Bearer $PRO_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"priceFeedIds":[1,2],"properties":["price"],"formats":["solana"],"channel":"fixed_rate@200ms","timestamp":1704067200000000}' \
  "https://pyth-lazer.dourolabs.app/v1/price"

Do not embed your Pro API key in frontend or browser applications. The key must stay server-side. Route requests through your own backend, which injects the Authorization header before forwarding to this API. A client-safe JWT authentication option is available for teams that do not want to run their own proxy. See the History API for details.

See Acquire an API Key to obtain a key.
