# Read the caller's evaluated feature flags

GET https://api.finput.com.au/api/v1/feature-flags

The full flag bag for the authenticated user, evaluated server-side. A client fetches this once on launch so flag-gated surfaces render correctly on first paint instead of flickering through default values.

A flag is not an entitlement. Flags control *rollout* — whether a feature is being served at all — while `GET /api/v1/billing/entitlements` says whether this caller's plan includes it.

**To decide what to show, use `surfaces`, not the flags.** It is each product surface's state already resolved from the rollout and the plan together, so a client renders it rather than re-deriving the paywall. The API still enforces every entitlement on the request itself.

`surface_reasons` and `limits` carry the words to show about a locked surface or a limit, worded for the client named in `X-Finput-Client`, so no client writes its own.

Reference: https://docs.finput.com.au/api/endpoints/feature-flags/get-feature-flags

## Authentication

- `Authorization` header (bearer token, required) — JWT access token obtained from `POST /api/v1/auth/login`, or a `finput_sk_...` API token

## Request

### Headers

- `X-Finput-Client` (enum, optional) — Which client is asking, so every `message` in the response is worded for it. `ios` and `android` get sentences that state a fact and nothing more: no plan, no price, no link. Absent means `web`, which keeps its existing wording. An unrecognised value is treated like `ios` and `android`.
  - Allowed values: `web`, `ios`, `android`

## Response

### 200

The evaluated flags.

- `surfaces` (Surfaces, optional) — What each product surface is for the caller. Resolved on the server; clients render it and must not recompute it from flags or entitlements.
- `surface_reasons` (SurfaceReasons, optional) — Why a surface is `locked`, worded for the client named in `X-Finput-Client`. Only locked surfaces have a key.
- `limits` (Limits, optional) — Each finite limit on a surface the caller can use. A key is absent when the limit does not apply: the plan is unlimited, or the surface is not usable.
- `flags` (map from string to FeatureFlagsResponseFlags, optional) — Rollout switches evaluated for the caller, keyed by flag name. Values are booleans or strings, so type this as a map of string to boolean-or-string. Flag names are not a public contract and change without notice. Decide what to show from `surfaces`, not from these.

## Errors

### 401 Unauthorized Error

Not authenticated.

- `error` (string, optional)
- `errors` (map from string to list of string, optional)

## Types

### Surfaces

What each product surface is for the caller. Resolved on the server; clients render it and must not recompute it from flags or entitlements.

- `calculator` (enum, required) — `available`: list it and serve it. `locked`: offered, but not on this account; `surface_reasons` has the sentence the calling client may show. `hidden`: do not list it; a deep link to it goes to `commercial_fallback`.
  - Allowed values: `available`, `locked`, `hidden`
- `matrix` (enum, required) — `available`: list it and serve it. `locked`: offered, but not on this account; `surface_reasons` has the sentence the calling client may show. `hidden`: do not list it; a deep link to it goes to `commercial_fallback`.
  - Allowed values: `available`, `locked`, `hidden`
- `matrix_calculator` (enum, required) — `available`: list it and serve it. `locked`: offered, but not on this account; `surface_reasons` has the sentence the calling client may show. `hidden`: do not list it; a deep link to it goes to `commercial_fallback`.
  - Allowed values: `available`, `locked`, `hidden`
- `consumer_calculator` (enum, required) — `available`: list it and serve it. `locked`: offered, but not on this account; `surface_reasons` has the sentence the calling client may show. `hidden`: do not list it; a deep link to it goes to `commercial_fallback`.
  - Allowed values: `available`, `locked`, `hidden`
- `mcp` (enum, required) — `available`: list it and serve it. `locked`: offered, but not on this account; `surface_reasons` has the sentence the calling client may show. `hidden`: do not list it; a deep link to it goes to `commercial_fallback`.
  - Allowed values: `available`, `locked`, `hidden`
- `commercial_fallback` (enum, required) — Where a hidden commercial surface sends the user: the calculator, or the Matrix Calculator when the calculator is itself hidden.
  - Allowed values: `calculator`, `matrix_calculator`

### SurfaceReasons

Why a surface is `locked`, worded for the client named in `X-Finput-Client`. Only locked surfaces have a key.

- `matrix` (string, optional)
- `matrix_calculator` (string, optional)
- `consumer_calculator` (string, optional)

### Limits

Each finite limit on a surface the caller can use. A key is absent when the limit does not apply: the plan is unlimited, or the surface is not usable.

- `calculator_runs` (Limit, optional)
- `matrix_runs` (Limit, optional)
- `saved_scenarios` (Limit, optional)
- `withheld_results` (Limit, optional)

### FeatureFlagsResponseFlags

### Limit

- `limit` (integer, required) — The number the limit allows: runs a day, saved scenarios per tool, or results with figures.
- `surfaces` (list of string, required) — The `surfaces` keys this limit applies to.
- `message` (string, required) — The limit, worded for the calling client.
