# ASN resources by country

`GET /api/v1/network/asn`

When ?country={cc} is provided, returns the ASN + IPv4 + IPv6 resource counts allocated to that country. Replaces the legacy /bgp/country/{cc}/resources path per spec section 12.

## Query parameters

- `country` string, required — ISO 3166-1 alpha-2 country code.
- `limit` integer — Max items per resource list (asn/ipv4/ipv6) in this page.
- `offset` integer — 0-based offset into each resource list.

## 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.
