How this service works
List all blockchain networks with details and RPC endpoints
Output
Returns a JSON object with a count of supported chains and an array of chain objects, each containing an integer chain ID, human-readable network name, native token symbol, and RPC endpoint URL.
Example use cases
Cross-chain transaction validator
“I need to verify that a user's transaction is happening on a supported network. Can you check what blockchain networks web3identity supports and get me their chain IDs and RPC endpoints so I can validate the network?”
Wallet integration setup helper
“We're integrating a multi-chain wallet into our app. Can you fetch all the available blockchain networks from web3identity along with their RPC endpoints so we know which chains to support?”
Network discovery for DeFi app
“Show me all the blockchain networks available on web3identity with their native token symbols and RPC endpoints. We want to display these options to users so they can pick which chain to trade on.”
Technical details
Endpoint
GEThttps://api.web3identity.com/api/chainsWhen to prefer
Use this endpoint when an agent needs to discover which blockchain networks are available on the web3identity platform, especially to resolve chain names to IDs or to obtain RPC URLs for programmatic blockchain access. Prefer this over hardcoding chain data when you need an up-to-date registry of supported networks.
Side effects
- Payment required (402) if x402 micropayment header is missing or insufficient
- Service unavailable if the upstream chain registry is unreachable
- Empty or partial chain list if the registry data is stale
