If the Snap is built with `GATSBY_SNAP_API_BASE_URL=https://explorer.d-bis.org`, then explorer.d-bis.org must serve this API (e.g. proxy `/api/v1/*` to this service). Otherwise build the Snap site with `GATSBY_SNAP_API_BASE_URL` set to this service’s public URL.

 ## Token list (report)
 
-**GET /api/v1/report/token-list** returns a Uniswap-style token list with **logoURI** per token and a list-level **logoURI**. Each token has: `chainId`, `address`, `symbol`, `name`, `decimals`, `type`, `logoURI`. Chain 138 also exposes staged GRU x402 deployments such as `cUSDT_V2` and `cUSDC_V2` explicitly, with optional metadata fields like `familySymbol`, `deploymentVersion`, and `preferredForX402`. Use for MetaMask token list URL or Snap `get_token_list`. Optional query `?chainId=138` filters by chain. If **TOKEN_LIST_JSON_URL** is set (e.g. GitHub raw URL), the service fetches that JSON and returns it (with optional chainId filter); otherwise uses the built-in canonical token list.

When `DEPLOYMENT_STATUS_JSON_PATH` / `CW_REGISTRY_JSON_PATH` points to `cross-chain-pmm-lps/config/deployment-status.json`, the endpoint reads that file at request time so explorer surfaces do not need a rebuild after registry edits.
