API status and configuration

Check service health, read network configuration, and monitor transaction status.

Health

GET /health

curl 'https://api.testnet.topokki.exchange/health'

{
  "status": "ok",
  "quoteState": "pending",
  "flashblocks": "enabled"
}

status is ok when the API dependencies are available, and degraded when one or more checks fail.

Configuration

GET /v1/config

curl 'https://api.testnet.topokki.exchange/v1/config'

{
  "chainId": 91342,
  "weth9": "0x4200000000000000000000000000000000000006",
  "quoterV2": "0x0aff314f898884c9ba81e4dcbf99f3e9d60ffd8f",

    "blockNumber": "0x1e102ab",
    "status": "0x1"
