Removes the caller's own access exactly as the owner removing them would (DELETE /api/computers/{id}/shares/{membership_id}): their access ends at once. A public computer still opens by its address; a private one needs a new invitation from the owner. ## OpenAPI ````yaml https://www.cool.computer/openapi.json delete /api/computers/{id}/membership openapi: 3.1.0 info: title: Cool Computers API version: 1.0.0 description: >- Create and operate reachable computers. Each computer keeps a stable name.cool.computer address, persistent files, and agent-ready command execution. REST requests use UTC-aligned one-minute limits: 600 requests per account identified by a recognized valid account bearer credential, a separate 600-request budget per computer-scoped credential, a separate 600-request browser budget per account for a browser session's same-origin app API requests and another for its document routes, or 60 requests per source IP otherwise (IPv6 addresses share their /64 network allowance). Read-only GETs answered from API state spend a separate read budget reported as account-read or computer-read, so status polling cannot exhaust the budget that protects work and mutations. To bound authentication-provider traffic, at most 60 first-seen credentials (bearers or browser cookies) are checked per source IP (IPv6 /64) in a minute; recognized valid credentials use their account or computer policy. Account bearer and browser-cookie authentication is reused for at most five seconds, with one shared validation for concurrent requests; transient provider failures are not cached. Computer tokens retain recognition for admission, but every authorized request checks their current database credential generation. Revoking a credential through this API (POST /api/auth/logout or DELETE /api/api-keys/{id}) fences it in every listening process. WorkOS holds shared session revocation state. A restarted process checks afresh; a missed notification leaves at most five seconds of credential reuse. If WorkOS cannot answer a revalidation, retry after the 503 response. JSON request bodies must be sent with Content-Type: application/json; any other body answers 415 unsupported_media_type. A request that gives a published site its own VM (POST /api/computers/{id}/vm, POST /api/computers/{id}/service/run, or a publish whose cool.json declares run) answers with a Cool-Notice header saying that the site now runs there and cool.json no longer applies; exec, terminals, the port proxy and exposure never give one and answer 409 needs_vm on a site with no VM. Every error is an application/problem+json object whose type links to https://cool.computer/docs/api-reference/errors; a malformed body names the unknown field, the wrong type, or the byte where the JSON breaks. Non-exempt API responses include the structured RateLimit and RateLimit-Policy fields; request admission 429 responses use code api_request_rate_exceeded and also include Retry-After. Health is exempt and shares its observation for one second. Browser sign-in routes under /auth/, including callbacks and logout, spend the existing source budget when called without a bearer. Other cookie requests without a same-origin signal retain the source budget, except document routes. Comment writes and steps sent without an Authorization header spend their own 60-request budget per source IP (comment-write). OpenAPI, provider webhooks, SSE, and WebSocket endpoints are exempt from the REST request budget. Anonymous counter saturation does not consume authenticated accounts' counter capacity; each scope has its own capped map, and new keys in a full map are refused until the next window. Authenticated SSE connection attempts remain subject to the authentication safeguards and can receive the same typed 429 response. servers: - url: https://api.cool.computer description: Canonical API origin security: [] tags: - name: Authentication description: Obtain and manage bearer credentials. - name: Billing description: >- Inspect and manage the account's plan: Free (sites with no VM, at most 20 at once) or Pro (adds VMs and any number of sites). - name: Computers description: Create, inspect, and delete resident computers. - name: Execution description: Run commands on a computer. - name: Files description: Read and change a computer's persistent files. - name: Publishing description: >- Publish files to a computer's URL as immutable releases, with no VM.
