# List sellers stocking a firearm

`GET /v1/firearms/{id}/offers`

## Request

- Base URL: `https://api.gunspec.io`
- URL: `https://api.gunspec.io/v1/firearms/{id}/offers`
- Auth: one of:
  - API key in header `X-API-Key`
  - HTTP bearer

Who stocks this firearm and where to buy it. The same three guards as an attachment's offers apply: only approved vendors appear, an offer not refreshed within 30 days is hidden, and `region` hides sellers who do not ship there. Offers link out; GunSpec never takes the order.

Available on every plan. Requires an API key; Explorer keys receive a reduced field set.

## Path parameters

- `id` string, required

## Query parameters

- `region` string

## Response `200`

List sellers stocking a firearm

- object
  - `success` boolean, required: Always true on a successful response. Every error carries `false` and an `error` object instead.
  - `data` PublicOffer[], required: The response payload.
    - `vendor` object: The shop stocking the part.
      - `id` string: Slug of the shop.
      - `name` string: Display name, as the maker writes it.
      - `website` string, nullable: Official website, where one is known.
      - `logoUrl` string, nullable: Absolute URL of the logo, or null where none is on file.
      - `verifiedDomain` string, nullable: The domain the shop has proved it controls, by a DNS record or a file on the site, re-checked daily. Null when it has not, which is not a sign the shop is untrustworthy: most have simply not done it yet.
    - `sku` string: The shop's own catalogue key for the listing. A seller's identifier, not ours: it is what `PATCH /v1/vendor/offers/{sku}` addresses.
    - `priceCents` integer: Price in integer minor units of `currency`, so cents for AUD. Never a float. Format with `Intl.NumberFormat` at render rather than dividing first.
    - `currency` string: ISO 4217 code the price is in, e.g. `AUD`. Prices are integer minor units; format with `Intl.NumberFormat` at render rather than dividing first.
    - `url` string: Absolute, directly fetchable URL.
    - `inStock` boolean: Whether the shop reports it in stock. Derived from `stockQty` where the shop tracks a count.
    - `clickId` string, nullable: Opaque token for the outbound link: send readers to `/v1/out/{clickId}` so the visit is counted for the seller. Null on a listing that cannot currently be followed.
    - `region` string, nullable: ISO 3166-1 alpha-2 code the seller ships to. Null means they state no restriction.
    - `updatedAt` string: When the seller last refreshed this listing. A listing not refreshed inside its freshness window is hidden rather than shown stale.

## Other responses

- `400`: Validation error
- `401`: Missing or invalid API key
- `403`: The credential is valid and the caller is not permitted. Three causes, none of which reissuing a key changes: the plan is below the endpoint's tier, the account is suspended, or the key is not attached to the thing being acted on, meaning a user account for `/v1/me` or a shop for `/v1/vendor`. Distinct from 401, which means the credential is missing, malformed or expired and a new one can work.
- `404`: Resource not found
- `429`: A limit was reached. `RATE_LIMITED` is the per-minute limit: wait `Retry-After` seconds (a minute) and retry. `DAILY_CAP_EXCEEDED` is the plan's daily limit, per key: nothing will be served until the counters return to zero at midnight UTC. `MONTHLY_CAP_EXCEEDED` is the plan's monthly allowance, for the whole account: nothing will be served until midnight UTC on the first of next month, or until the plan changes. For both, `Retry-After` is the seconds until then and `error.resetsAt` says when as an instant. Calls made after a refusal are refused too and do not spend the month, and a free key that keeps calling is paused, so stop at the first one and resume at the reset.
- `500`: Internal server error
