# Per-model cost rollup for the org

`GET /orgs/{org_id}/costs`

## Request

- Base URL: `https://api.mnemom.ai/v1`
- URL: `https://api.mnemom.ai/v1/orgs/{org_id}/costs`
- Auth: HTTP bearer

Daily usage broken down by model with a USD cost estimate per row plus aggregate totals. Cost figures are estimates derived from Mnemom's published per-model pricing applied to your actual token volume; authoritative billing is in Stripe (see `POST /orgs/{org_id}/billing/portal-session`). Billing-shaped — `owner`, `admin`, and `auditor` only.

## Path parameters

- `org_id` string, required

## Query parameters

- `days` integer

## Response `200`

Daily cost rows + totals.

- object
  - `period` string
  - `days` integer
  - `data` object[]
    - `date` string, date
    - `model` string
    - `tokens_in` integer
    - `tokens_out` integer
    - `request_count` integer
    - `cost_usd` number

    - `total_tokens_in` integer

## Other responses

- `400`: Bad request
- `401`: Authentication required
- `403`: Forbidden
- `404`: Resource not found
- `409`: Resource conflict — the request cannot proceed because of a current state conflict (e.g., resource already exists, version mismatch, in-flight idempotency key with a different body).
- `429`: Rate-limit exceeded. The global per-IP limiter (100 requests/minute, applied to every `/v1/*` route) rejected this request. Back off until the window resets — `Retry-After` carries the cooldown in seconds and `X-RateLimit-Reset` the absolute reset time.
- `500`: Server error — request was well-formed but the server failed to fulfill it. Typically a downstream dependency (DB / RPC / external API) returned an unexpected error.
