Defined in: packages/synapse-core/src/pdp-verifier/find-piece-ids-by-cid.ts:76

Find piece IDs for a given PieceCID in a data set.

Uses the on-chain findPieceIdsByCid function for efficient CID→ID lookup.

Parameters

Parameter	Type	Description
client	Client<Transport, Chain>	The client to use to find piece IDs.
options	OptionsType	findPieceIdsByCid.OptionsType

Returns

Promise<OutputType>

Array of piece IDs matching the CID findPieceIdsByCid.OutputType

Example

import { findPieceIdsByCid } from '@filoz/synapse-core/pdp-verifier'
import { calibration } from '@filoz/synapse-core/chains'
import { createPublicClient, http } from 'viem'
import * as Piece from '@filoz/synapse-core/piece'

const client = createPublicClient({
  chain: calibration,
  transport: http(),
})

const pieceCid = Piece.parse('bafkzcibcd4bdomn3tgwgrh3g532zopskstnbrd2n3sxfqbze7rxt7vqn7veigmy')
const pieceIds = await findPieceIdsByCid(client, {
  dataSetId: 1n,
  pieceCid,
})
// pieceIds is an array of bigint IDs matching the CID

Throws

Errors findPieceIdsByCid.ErrorType
