---

1. Quick start

# Global snapshot – every chain
curl -X POST <https://api.polymer.zone/v1> \\
  -H 'Content-Type: application/json' \\
  -d '{"jsonrpc":"2.0","id":1,"method":"info_health","params":[{}]}'

# Solver check – only the chains you quote
curl -X POST <https://api.polymer.zone/v1> \\
  -H 'Content-Type: application/json' \\
  -d '{"jsonrpc":"2.0","id":1,"method":"info_health","params":[{"chain_ids":[1,42161,8453]}]}'

2. Behaviour matrix

Caller intent	Param shape	Returned data
Full health map	params: [{}] or params: [{chain_ids:[]}]	status map of every supported chain
Solver/Specific view	params: [{"chain_ids":[<int>,…]}]	status map only for the requested chains

Note: params must be an array with exactly one element:

3. Response schema

Success body:

{
  "jsonrpc": "2.0",
  "id": 1,
  "result": {
    "status": {
      "< chainId >": "healthy" | "unhealthy",
      ...
    }
  }
}
