# Port catalog

`GET /api/v1/maritime/ports`

IMF PortWatch port catalog (~2000+ ports worldwide) with country, coordinates, top industries, vessel counts by type, and share of country maritime trade. Use limit up to 5000 to request the full catalog; the client pages ArcGIS results so requests are not silently capped at 1000.

## Query parameters

- `country` string — Filter by ISO3 country code (e.g. USA, CHN, JPN)
- `limit` integer — Maximum number of records to return (full PortWatch catalog is ~2000+ ports).

## Other responses

- `401` — Missing or invalid `x-api-key` header. JSON body with a stable `code` distinguishing `missing_api_key` (no header sent) from `invalid_api_key` (header sent, key not accepted); any other 401 source carries the generic `unauthorized` with its detail as `reason`. Plus `hint`. `plan` is always null on 401 - an unauthenticated request has no plan; quota exhaustion is 429, not 401.
- `422` — Validation Error
- `429` — Daily rate limit exceeded. Check `X-RateLimit-Reset` for the next window.
- `503` — Upstream source is temporarily unavailable. Retry after a short delay.
