How this service works
Look up any EVM chain by id or name - native currency, public RPC URLs, block explorers, testnet flag, faucets, status and website from chainid.network
Output
Returns a JSON object with the interpreted query, number of matches, and an array of matching chain objects — each containing chain ID, network ID, name, short name, native currency details, public RPC URLs, block explorer URLs, testnet boolean, faucet URLs, official website, current status, and parent chain info for L2s. Also includes a source attribution (chainid.network) and optional notes.
Example use cases
Configure wallet for new EVM chain
“I need to add Arbitrum One to my MetaMask — what's the chain ID, RPC URL, native currency, and block explorer for it?”
Find faucet for testnet development
“I'm developing on Sepolia testnet, can you look up the faucet URLs and RPC endpoints so I can fund my test wallet?”
Verify if a chain is a testnet
“Is chain ID 80001 a testnet or mainnet, and what's its official name and status?”
Technical details
Endpoint
GEThttps://saylorinnovations.com/api/evm/chain-info?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need authoritative EVM chain metadata such as RPC URLs, block explorers, native currency, or testnet status for any EVM-compatible network. It covers a wide range of chains sourced from chainid.network and is ideal for wallet configuration, developer tooling, chain validation, or any agent workflow that needs to programmatically resolve chain details from a name or numeric ID. Prefer this over hardcoded configs when you need up-to-date or lesser-known chain information.
Side effects
- No matching chains found for the given query — returns empty chains array
- Ambiguous name fragment matching multiple chains — returns all matches, agent must disambiguate
- Chain exists in chainid.network but has no public RPCs listed — field may be empty
- Stale data if chainid.network has not been recently updated for newer or deprecated chains
- Invalid or non-EVM chain ID returns no results
