Nothing is stored when Anthropic refuses the key (`anthropic_key_refused`, 422) or when the check cannot reach Anthropic (`anthropic_key_check_unavailable`, 502). Answers with the key's last four characters, never the key. Answers 404 unless the `managed-runners` flag is on for the organization. ## OpenAPI ````yaml /openapi.yaml put /v1/apps/{appId}/anthropic-key openapi: 3.0.3 info: contact: email: hello@outerlayer.ai url: https://www.outerlayer.ai description: >- The OuterLayer Gateway API lets you ingest coding-agent sessions and record evidence of work programmatically. Most teams reach it through the `outerlayer` CLI, which calls it for them. Call it directly to build your own integration or to automate what the dashboard does. Versioning: every endpoint is prefixed with `/v1/`. Breaking changes ship under a new version prefix (`/v2/`, etc.) with a 90-day-minimum deprecation window; anything additive lands on the current prefix. Vocabulary: the dashboard calls this API's `app` a **factory** — the unit that owns a set of repositories, the agent sessions worked on them, and the evidence they produce. They are the same entity. The API keeps `app` in its paths, headers, and field names because those are a published contract; only the product surface was renamed. title: OuterLayer Gateway API version: '1.0' servers: - description: Production (OuterLayer Cloud) url: https://api.outerlayer.ai - description: Local dev server (self-hosted gateway) url: http://localhost:9418 security: - AppId: [] BearerAuth: [] tags: - description: >- What a CLI login token can read about its owner without naming a factory, such as the factories they can use. name: Account - description: >- The CLI version a gateway names to its runners, set with the gateway's runner version key. name: Runner version - description: >- Coding-agent session ingest (outerlayer sync) and content-addressed session images. name: Agents - description: >- Evidence artifacts (screenshots, recordings, reports, logs) emitted as proof of a change and anchored to pull requests. name: Artifacts - description: >- Pass/fail outcomes of checks run in your own CI or compute, anchored to pull requests with the run URL as proof. name: Emitted Results - description: >- The acceptance criteria of a work item, recorded as one list.
