Request body

application/json

Send a JSON object with these fields.

channelRequired

The channel that determines the update frequency.

real_time
fixed_rate@50ms
fixed_rate@200ms
fixed_rate@1000ms

formatsRequired

Payload formats to include in each update, with no duplicates. An empty array requests no binary payloads. With a payload format, a request can include at most 255 feeds.

evm
solana
leEcdsa
leUnsigned

propertiesRequired

Feed properties to include in each update. Specify at least one property. Duplicate values are not allowed.

feedUpdateTimestamp

Feedsone of the 2Required

Provide either priceFeedIds or symbols, but not both. Use numeric IDs, such as 1 for BTC/USD, or symbols, such as Crypto.BTC/USD. The array must contain at least one entry and no duplicates.

Select feeds by pyth_lazer_id in priceFeedIds, not by symbol. Feed symbols can change when we correct symbology, and a symbol may later point to a different asset. A pyth_lazer_id never changes.
