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, or 60 requests per source IP otherwise. 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 bearer values are checked per source IP in a minute; recognized valid credentials use their account or computer policy. Successful bearer authentication is reused for at most five seconds; transient provider failures are not cached. 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, OpenAPI, webhooks, callbacks, SSE, and WebSocket endpoints are exempt from the REST request budget. 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 no-card trial or Pro plan. - 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.
