ds_list_feeds

List available Chainlink Data Streams feeds. Returns feed IDs, pairs, and asset classes (crypto, forex, equities, commodities). Data Streams provide sub-second latency market data — distinct from the slower on-chain Data Feeds.

Parameters1

asset_class

string | null

optional

Filter by asset class: 'crypto', 'forex', 'equities', 'commodities' (optional)

por_get_reserve

Read a Chainlink Proof of Reserve feed to verify asset reserves onchain. Uses the same AggregatorV3Interface as price feeds but returns reserve amounts instead of prices. Well-known PoR feeds on Ethereum: WBTC = 0xa81FE04086865e63E12dD3776978E49DEEa2ea4e, USDC = 0x9a177Bb065A0636C7972C6D27Abcd4B1e5EDb65c, TUSD = 0x478f4c42b877c697C4b19E396865D5437Ef4E08B.

Parameters2

feed_address	string	required	Proof of Reserve feed contract address (hex). Well-known: WBTC=0xa81FE04086865e63E12dD3776978E49DEEa2ea4e, USDC=0x9a177Bb065A0636C7972C6D27Abcd4B1e5EDb65c
chain	string \| null	optional	Chain: 'ethereum'. Defaults to 'ethereum'

vrf_request_random

Build transaction calldata for a VRF v2.5 random words request. Returns the hex-encoded calldata for VRFCoordinatorV2_5.requestRandomWords(). The caller must sign and submit the transaction from a consumer contract. VRF v2.5 supports payment in LINK or native token.
