REST API

Retrieve info about messages using REST Queries
The Hyperlane agents collect useful information about activity on the system, including all messages. That data can be queried via the APIs.
The APIs are currently available free of charge and without any required authentication.
Connect your preferred fetch client or library to Explorer API page to query data!
Example Query

APIs for Permissionless Interoperability chains 
Hyperlane can be permissionlessly deployed to any chain, but messages on PI chains cannot be identified by the default Hyperlane agents. To view details about messages from PI chains, query the search-pi-messages action. The search requires a chain config in the request body. Note, this same functionality is also available in the explorer UI.
const chainConfig = {
  "chainId": 1234,
  "name": "mychain",
  "publicRpcUrls": [{ "http": "https://myRpcUrl.com" }],
  "blockExplorers": [ {
      "name": "MyChainScan",
      "url": "https://myChainExplorer.com",
      "apiUrl": "https://myChainExplorer.com/api",
      "apiKey": "12345"
  } ],
  "contracts": {
    "mailbox": "0x123..."
  }
}

Chain Config Schema
The chain config schema is an extension of the Hyperlane SDK's ChainMetadata schema but with a contracts object added. See Configuring PI Chains for more details about this config object.
