EVM Chain Registry by Chain ID

chainid/chain-by-id

Registry entry for one EVM chain by chain id: name, short name, native currency (symbol and decimals), public RPC URLs, block explorers, info URL, network id, parent chain for rollups, and ENS or faucet details when listed. Some RPC URLs contain key placeholders such as ${API_KEY}, which are not usable as-is.

// 1. search: find the tool
omnial_search({ query: "what you need" })

// 2. inspect: price and input schema
omnial_inspect({ tool: "chainid/chain-by-id" })

// 3. learn: read the usage guide at runtime
omnial_learn({ tool: "chainid/chain-by-id" })

// 4. run: price the exact call first, then run it
omnial_execute({ tool: "chainid/chain-by-id", input: { /* see input_schema */ }, dry_run: true })
omnial_execute({ tool: "chainid/chain-by-id", input: { /* ... */ } })

// 5. settle: the call is charged when it finishes, nothing to do
