NOTE: copyright detection is not yet available in the knowledge base. The endpoint currently resolves the component identity and returns an empty `files` array with `info_code: NO_INFO`. The response contract is final. ## OpenAPI ````yaml /api-reference/developer-tools/v3-openapi.yaml post /v3/copyright/evidence openapi: 3.0.3 info: title: SCANOSS Services API version: 0.28.1 description: | Consolidated HTTP API for the SCANOSS knowledge base. Exposes the following domains under a single `/v3/*` prefix: * **licenses** — attribution files + per-file license evidence * **copyright** — copyright evidence + holders (stubbed pending data) * **components** — free-form search, versions and lifecycle status * **crypto** — algorithms, hints and version ranges per purl, plus ruleset tarball downloads * **crypto reachability** — stitched cryptographic findings, call chains, entry points, supporting and forward calls per component or frozen dependency tree * **dependencies** — declared dependencies (with composite-license resolution) and bounded transitive walks * **geo** — contributor declared/curated locations and timezone-based origin distribution * **vulnerabilities** (path `/vuln/*`) — CVE detection by merging the local NVD KB with osv.dev, enriched with EPSS * **scan** — direct SCANOSS engine scans (WFP upload, MD5 / urlhash / snippet lookups) * **contents** — raw notice / source-code content from the mz store Every batch endpoint encodes per-item failures as `info_code` / `info_message` so the call as a whole returns 200 with a `status.status` ∈ {SUCCESS, PARTIAL_SUCCESS, ERROR}. Single-purl GETs derive the same status from the item's `info_code`. servers: - url: https://api.scanoss.com description: Production security: [] tags: - name: licenses description: License attribution files and per-file license evidence - name: copyright description: Copyright evidence and holders (stubbed pending KB data) - name: components description: Component search, versions and lifecycle status - name: cryptography description: Cryptographic algorithms, hints, version ranges and ruleset downloads - name: cryptography-reachability description: > Crypto reachability over mining results: stitched findings, call chains, crypto entry points, supporting calls and bounded forward calls, for one component (with its mined dependency closure) or a caller-supplied frozen dependency tree.
