chains

Retrieve CCIP chain information

Returns information about Cross-Chain Interoperability Protocol (CCIP) chains across different blockchain families (EVM, Solana, Aptos)

get/chains

Query parameters

environment'mainnet' | 'testnet' required

The network environment to query

chainIdstring

Filter by chain ID (e.g., "1" for Ethereum, "56" for BSC, or a Solana pubkey)

selectorstring

Filter by CCIP chain selector. Multiple selectors can be specified using comma-separated values

internalIdstring

Filter by internal chain identifier. Multiple IDs can be specified using comma-separated values (e.g., "ethereum-mainnet,bsc-mainnet")

outputKey'chainId' | 'selector' | 'internalId'

Key to use for organizing the response data

enrichFeeTokens'true' | 'false'

When set to 'true', returns detailed fee token information including addresses, names, and decimals instead of just symbol strings

searchstring

Unified search query. Automatically detects query type: selector (>17 digits), chainId (≤17 digits or Solana base58 hash), internalId (kebab-case), or displayName (fuzzy text search). Cannot be combined with chainId, selector, or internalId filters.

Filter results by chain family. Only effective when using the search parameter.

Response

Successful response with chain data
