# Get inference providers' prices for a token model

`GET /v1/series/offers`

## Request

- Base URL: `https://api.liquidcompute.co`
- URL: `https://api.liquidcompute.co/v1/series/offers`
- Auth: API key in header `X-API-Key`

Returns a token model and each inference provider's list price for
it, in US dollars per million tokens, cheapest input first. The
prices are those of the newest period (`period_start`, the UTC day
the price list was read) holding any, each provider's most recent
reading of it. Free, batch and explicitly quantized offers are
excluded.

A closed model is priced by its lab alone, so it lists no offers;
nor does an open-weights model before its first reading, and then
`period_start` is `null`. An unknown model returns `404`.

Requires the `reference-series` entitlement family; requests without
it return `404` `not_found`.

## Query parameters

- `model` string, required

## Response `200`

The model and its providers' prices.

- ReferenceSeriesOffersResponse
  - `model` TokenModel, required
    - `id` string, required
    - `name` string, required
    - `lab` string, required: The lab that publishes the model.
    - `class` 'premium' | 'flagship' | 'mid' | 'small' | 'open', required: Price class. A closed model's class is its place in its lab's own lineup, priced at the lab's list price; `open` is an open-weights model, priced as the median across inference providers.
    - `open_weights` boolean, required
    - `position` integer, required: Display order across all token models, ascending.
    - `succeeds` string, nullable, required: Id of the model this one replaced in the same lab and price class; null when it replaced none. A model that no other model succeeds is current: the ladder shows current models, and a class's price history follows each one back along this chain.
  - `period_start` string, date, nullable, required: The UTC day the prices were read; null when there are no offers.
  - `offers` TokenOffer[], required
    - `company` string, required: The inference provider.
    - `input` number, required: List price per million input tokens, USD.
    - `output` number, required: List price per million output tokens, USD.
    - `cached_input` number, nullable, required: List price per million cached input tokens, USD; null when the provider lists none.

## Other responses

- `400`: Invalid or unsupported query parameter.
- `401`: Missing or invalid API key.
- `404`: Unknown endpoint, unavailable resource, or an index or index family outside your authorization.
