Price: 5 credits. ## OpenAPI ````yaml api-reference/openapi.standard.json GET /companies/{id}/branches openapi: 3.1.0 info: title: Syrto API - standard endpoints version: 1.7.0 description: >- Financial, corporate and market data on Italian companies. Every call answers `200 { data, meta }`; `meta.usage.quantity` is what the call consumed, in credits, and `meta.warnings` lists any non-fatal caveats (empty when there are none). Every field is always present and unknown values are null. Percentages are fractions (0.15 = 15%). **Authentication.** Every call needs an API key, sent as `Authorization: Bearer sk_...` over HTTPS - never in a URL. Keys are scoped to your organization: admins create and revoke them in the Syrto dashboard (https://dashboard.syrto.ai/api-keys). A missing or unrecognised key is a 401 (`missing_api_key`, `invalid_api_key`); a 503 `auth_unavailable` means the key could not be checked right now, so retry with backoff rather than rotating it. **Billing basis.** negativities, rna and structure bill once per legal entity: the individual and consolidated records of the same company count once. Every other endpoint bills per record (or per call), so individual and consolidated count separately. A tax id always resolves to a single record (`statementBasis`, individual by default): a company is billed twice only when both of its companyIds are passed. A market call is priced per call, whatever the size of its set: omitting `filters` and `seedId`, or sending `filters: {}`, is the whole of Italy, at the same price. notFound entries are never billed, and neither is any error. servers: - url: https://api.syrto.ai security: [] tags: - name: Company data description: Identity, risk flags, state aid and branches of known companies. - name: Governance description: Ownership, officers, beneficial owners and group. - name: Financials description: Statement items, reclassified statements, indices and spider graph. - name: Composite description: Comparable companies. - name: Search description: The companies of a filtered set, row by row. - name: Market description: Aggregates over a filtered set. - name: Catalog description: Free reference data. paths: /companies/{id}/branches: get: tags: - Company data summary: Registered office and every registered branch of one company. description: >- All branches in one response (up to 1000; `truncated` says when there are more).
