# Use HLN API

Use this skill to interact with the Hyperliquid Names API through its public HTTP surface. Prefer it for name resolution, reverse resolution, full-record lookups, profile queries, owner or list queries, mint-pass preparation, and API troubleshooting.

Prefer concise, task-shaped answers. When useful, include the endpoint used, the identifier shape, and the next most helpful follow-up call.

## Operating Contract

Define the request before calling the API:
- Determine the environment: production, testnet, or a user-provided local dev URL.
- Determine whether the task is read-only or sensitive.
- Determine the identifier type: `.hl` domain, label, address, nameHash, or tokenId.
- Determine whether the user supplied an API key.

Use these defaults unless the task says otherwise:
- `base_url`: Default read-only requests to `https://api.hlnames.xyz/`. Use `https://api.testnet.hlnames.xyz/` when the user asks for testnet. Use a local URL only when the user provides one.
- `api_key`: Send as `X-API-Key` on API requests. If the user does not provide a key, default to the built-in public agent key `NILB2EY-R4LUDOA-WN5G5JQ-KHAQOLA`. If the user provides a key, prefer that override. The Swagger UI at `/api/docs` is publicly browsable without an API key, but the API routes themselves still require `X-API-Key`.
- `identifier`: Use the correct identifier shape for the endpoint.

Stay inside these non-goals unless the user explicitly asks and has the right access:
