# Sandbox mirror of /api/v1/company/{org}/accounts (API key or sandbox bearer)

`GET /api/v1/sandbox/company/{org}/accounts`

## Request

- Base URL: `https://www.apier.no`
- URL: `https://www.apier.no/api/v1/sandbox/company/{org}/accounts`
- Auth: one of:
  - HTTP bearer
  - HTTP bearer

Authenticated sandbox mirror of `GET /api/v1/company/{org}/accounts`. Returns the same deterministic annual-accounts status as the production endpoint, computed over in-code synthetic fixtures — same input yields the same response (excluding `_meta.response_timestamp`). Reserved test orgs, reserved error orgs, and `?simulate_error=<code>` are documented on `/api/v1/capabilities`. CORS is open (`Access-Control-Allow-Origin: *`) so browser-based agents can fetch from any origin. Authentication accepts a real API key or a synthetic `apier_sandbox_test_<suffix>` bearer — no real Apier key is required to explore the sandbox. Synthetic data only.

## Response `200`

Sandbox 2xx success for `GET /api/v1/sandbox/company/{org}/accounts`. Body shape is the typed `SandboxAccountsEnvelope` — `{ success: true, data: CompanyAccounts, _meta: SandboxMeta }`.

- SandboxAccountsEnvelope: Sandbox 2xx success envelope BASE shape. Top-level keys mirror the production envelope (`success`, `_meta`) so SDK clients consuming sandbox responses see identical shapes. The `data` field is intentionally omitted from the base — per-operation envelopes (`SandboxContextEnvelope`, `SandboxObligationsEnvelope`, ...) `allOf` this base and pin `data` to the operation's typed payload, so generated clients keep the mirror typing for each route.
  - `success` true, required
  - `_meta` SandboxMeta, required: Sandbox `_meta` block. NOT a drop-in for production's `TrustMetadata`; clients must branch on `is_sandbox` before assuming any sandbox/production field equivalence. Differences from production: 1. `is_sandbox: true` — load-bearing detection signal; `body._meta.is_sandbox === true` is a single property assertion agents use to verify they're talking to the sandbox. Production omits this key entirely. 2. `rulebook_version` is the literal string `"sandbox"` — production carries the actual Rulebook version (e.g. `"v1.0.0"`). Sandbox responses are not Rulebook-evaluated. 3. `data_freshness` and `last_verified` are pinned constants (2026-01-01T00:00:00+01:00) — production reflects actual cache / fetch state. 4. `response_timestamp` is RFC 3339 with explicit Europe/Oslo offset (`+01:00` CET / `+02:00` CEST, DST-aware) — production's `response_timestamp` carries a UTC `Z` suffix. 5. `response_hash` and `source_snapshot_id` are OMITTED — sandbox writes ZERO provenance_log rows, so a hash without a matching forensic row would be misleading. Only `source` (`"apier.no"`) and `schema_version` semantics are shared with production.
    - `rulebook_version` 'sandbox', required: Always literal `sandbox` — sandbox responses are not Rulebook-evaluated.
    - `data_freshness` '2026-01-01T00:00:00+01:00', date-time, required: Pinned constant (2026-01-01T00:00:00+01:00) for determinism — same value on every call. Schema-locked via `enum` so spec-based drift checks catch any deviation.
    - `last_verified` '2026-01-01T00:00:00+01:00', date-time, required: Pinned constant — equal to data_freshness. Schema-locked via `enum` for the same drift-detection reason.
    - `source` 'apier.no', required: Response origin. Always `apier.no`. Preserves `_meta.source` parity with production `TrustMetadata.source` so clients can reuse `_meta` parsing across both surfaces. Provenance-specific fields (`response_hash`, `source_snapshot_id`) are omitted by design.
    - `schema_version` string, required: OpenAPI document version — mirrors the top-level `info.version` field. Distinct from `/api/v1/capabilities._meta.schema_version` and `/workflows.json.schema_version`, which version the capabilities-discovery and workflows-discovery surfaces respectively. Equality with `info.version` is enforced at CI time.
    - `is_sandbox` true, required: Load-bearing sandbox-detection signal. Always `true`.
    - `response_timestamp` string, date-time, required: RFC 3339 timestamp with explicit Europe/Oslo offset — runtime emits via `formatInTimeZone(now, 'Europe/Oslo', "yyyy-MM-dd'T'HH:mm:ssXXX")` so the offset is DST-aware (`+01:00` in CET / `+02:00` in CEST). The ONLY non-deterministic field permitted on sandbox responses (excluded from determinism comparisons).
    - `sandbox_notice` string, required: Human-readable mock-vs-government honesty signal (item 5). Constant prose: a passing sandbox run is an Apier internal mock (not Altinn TT02 / Skatteetaten test) and does not guarantee real government acceptance. `is_sandbox` is the machine-readable twin; this is the prose an agent or a human reading a logged response sees. Plain ASCII so it never trips the docs bokmål canary.
    - `cost_nok` 0: Always `0`. A sandbox call never debits anything — there is no ledger write and no government upstream. Same field name and rendering as production's `TrustMetadata.cost_nok`, so a client that reads the cost off `_meta` works unchanged against both surfaces. Emitted on every sandbox response. Declared optional in this schema only so the many older sandbox examples in this document stay valid; the runtime builder emits it on every response.
    - `wallet_remaining_nok` unknown
    - `as_of` string: Present ONLY when `?as_of=` Rulebook time travel is active on /deadlines or /obligations. Echoes the agent's exact YYYY-MM-DD input so a transcript is self-describing about which reference date the deadline / obligation statuses were derived against. Absent on every other sandbox response.
    - `simulated` true: Present + `true` ONLY on an `X-Apier-Simulate` injected failure response. The load-bearing signal that a 500 / 504 / 429 is a deliberately-simulated infrastructure failure, not a real one. Absent on every real sandbox response.
    - `session_merged` true: Present + `true` ONLY when this response merged per-suffix session state (mock filings recorded by a prior POST /api/v1/sandbox/actions/execute under the SAME sandbox-bearer suffix) over the static fixture, on the three opted-in reads (/audit, /obligations, /summary). The honesty marker distinguishing fixture state from session state. Absent on every fresh-suffix response, which stays byte-deterministic.
    - `session_merged_rows` integer: Count of response items the merged session state changed (obligation/deadline statuses overridden plus audit rows prepended). Present ONLY alongside `session_merged: true`, always >= 1.
  - `data` CompanyAccounts, required: Body of GET /api/v1/company/{org}/accounts. Current-snapshot only (v1) — filing status + the most-recent year's minimal key figures from the OPEN Regnskapsregisteret tier (no multi-year history, no closed/authenticated tier). `has_filed_annual_accounts` is tri-state and NEVER coerced: `null` = the open tier was unavailable or does not cover the entity, distinct from an authoritative `false` (covered but none on file).
    - `org_number` string, required: 9-digit Norwegian organisation number the snapshot is about.
    - `has_filed_annual_accounts` boolean, nullable, required: Tri-state filing status. `true` = at least one annual-accounts record on file; `false` = the register authoritatively reports none for a covered entity; `null` = unknown (open tier unavailable / does not cover the entity, e.g. banks & insurers filing via a separate oppstillingsplan). NEVER coerced `null` → `false`.
    - `last_accounts_year` integer, nullable, required: Calendar year (Europe/Oslo) of the most-recent annual-accounts record on file, or null when none / unknown.
    - `key_figures` CompanyAccountsKeyFigures, required: Minimal latest-year key figures from the OPEN Regnskapsregisteret tier. Every field is independently nullable — the open tier omits fields for some entity types / presentation plans. Monetary amounts are whole units of `currency`.
      - `currency` string, nullable, required: `valuta` — reporting currency. Surfaced first and never omitted so the monetary figures below are never silently read as NOK (large issuers report in USD/EUR). Null when the upstream omitted it.
      - `presentation_basis` string, nullable, required: `oppstillingsplan` — presentation basis (e.g. "smaaForetak", "store"). Null when omitted.
      - `sum_assets` number, nullable, required: `eiendeler.sumEiendeler` — total assets, in `currency`.
      - `annual_result` number, nullable, required: `resultatregnskapResultat.aarsresultat` — net annual result, in `currency`.
      - `operating_result` number, nullable, required: `resultatregnskapResultat.driftsresultat.driftsresultat` — operating result, in `currency`.
      - `equity_and_liabilities` number, nullable, required: `egenkapitalGjeld.sumEgenkapitalGjeld` — total equity + liabilities, in `currency`.

## Other responses

- `400`: Sandbox 4xx / 5xx error. Body shape mirrors the production error envelope (`{ success: false, error_code, explanation, _meta }`); `explanation` is the Compliance Explainer's full Norwegian-bokmål `{ summary, why, fix_steps[], relevant_link, legal_basis, handover }`. The Cache-Control header is `no-store` so transient failures aren't pinned in the Edge cache.
- `401`: Sandbox 4xx / 5xx error. Body shape mirrors the production error envelope (`{ success: false, error_code, explanation, _meta }`); `explanation` is the Compliance Explainer's full Norwegian-bokmål `{ summary, why, fix_steps[], relevant_link, legal_basis, handover }`. The Cache-Control header is `no-store` so transient failures aren't pinned in the Edge cache.
- `403`: Sandbox 4xx / 5xx error. Body shape mirrors the production error envelope (`{ success: false, error_code, explanation, _meta }`); `explanation` is the Compliance Explainer's full Norwegian-bokmål `{ summary, why, fix_steps[], relevant_link, legal_basis, handover }`. The Cache-Control header is `no-store` so transient failures aren't pinned in the Edge cache.
- `404`: Sandbox 4xx / 5xx error. Body shape mirrors the production error envelope (`{ success: false, error_code, explanation, _meta }`); `explanation` is the Compliance Explainer's full Norwegian-bokmål `{ summary, why, fix_steps[], relevant_link, legal_basis, handover }`.

- `422`: Sandbox 4xx / 5xx error. Body shape mirrors the production error envelope (`{ success: false, error_code, explanation, _meta }`); `explanation` is the Compliance Explainer's full Norwegian-bokmål `{ summary, why, fix_steps[], relevant_link, legal_basis, handover }`. The Cache-Control header is `no-store` so transient failures aren't pinned in the Edge cache.
- `429`: 429 emitted ONLY by the X-Apier-Simulate: rate_limit failure injection on the authenticated sandbox company READ routes. Body is the standard SandboxEnvelopeError (error_code RATE_LIMIT_EXCEEDED); _meta.simulated:true marks it a deliberate injection, NOT a real per-key/per-org limiter block — the simulation gate short-circuits BEFORE the rate limiter so the real bucket is never consumed (zero quota burned). Distinct from SandboxError so the Retry-After contract (always 30s) is documented exactly where the simulated 429 appears.
- `500`: Sandbox 4xx / 5xx error. Body shape mirrors the production error envelope (`{ success: false, error_code, explanation, _meta }`); `explanation` is the Compliance Explainer's full Norwegian-bokmål `{ summary, why, fix_steps[], relevant_link, legal_basis, handover }`. The Cache-Control header is `no-store` so transient failures aren't pinned in the Edge cache.
- `504`: Sandbox 4xx / 5xx error. Body shape mirrors the production error envelope (`{ success: false, error_code, explanation, _meta }`); `explanation` is the Compliance Explainer's full Norwegian-bokmål `{ summary, why, fix_steps[], relevant_link, legal_basis, handover }`. The Cache-Control header is `no-store` so transient failures aren't pinned in the Edge cache.
