openapi: 3.1.0 info: title: Coasty Public keys triggers API version: 1.0.0 summary: Computer Use Agents, scheduled automation, and managed VMs. description: "# Coasty Public API\n\nCoasty is a Computer Use Agent (CUA) platform: predict actions from screenshots,\nprovision managed VMs, and run scheduled automation against them.\n\n## Authentication\n\nAll endpoints (except `/v1/triggers/webhook/{webhook_id}` and health checks) require an API key.\nPass it as either:\n\n- `X-API-Key: sk-coasty-live-...` (or `sk-coasty-test-...` for sandbox)\n- `Authorization: Bearer sk-coasty-live-...`\n\nThe external webhook endpoint does not use an API key, but it is authenticated:\nsend the HMAC-SHA256 `Coasty-Signature` credential documented on that operation.\n\nTest-mode keys (`sk-coasty-test-*`) hit the same validation paths as live keys but\nreturn mock VMs / mock action results and never bill credits — ideal for CI.\n\n## Pricing & budgeting\n\nPer-call rates (subject to change — see `lib/pricing/tiers.ts METERED_RATES`):\n\n| Endpoint | Credits |\n|---|---|\n| `POST /v1/predict` | ~5 |\n| `POST /v1/sessions` | 10 |\n| `POST /v1/sessions/{id}/predict` | ~4 |\n| `POST /v1/ground` | ~3 |\n| `POST /v1/parse` | 0 (free) |\n\nLong-running CUA jobs orchestrated through the dashboard (not this API) bill at\n10 credits/minute with a 20-credit minimum. Subscription tiers (`free | starter |\nprofessional | enterprise`) gate feature availability (e.g. custom system prompts),\nschedule counts, and the maximum trajectory length.\n\n## Errors\n\nEvery error response uses the same envelope:\n\n```json\n{\n \"error\": {\n \"code\": \"INSUFFICIENT_CREDITS\",\n \"message\": \"Need 5, have 2.\",\n \"type\": \"billing_error\",\n \"request_id\": \"req_a1b2c3d4e5f6\",\n \"retryable\": false,\n \"retry_with_same_idempotency_key\": false\n }\n}\n```\n\nInclude the `request_id` in support requests.\n\n## Idempotency\n\nOperations marked `x-idempotency: reserve-and-replay` accept `Idempotency-Key:\n<≤128 chars of [A-Za-z0-9_-:]>`. Replays\nof the same key + identical body return the original response (with\n`X-Coasty-Idempotent-Replay: true`) for 24 h. Reusing the key with a different body\nis a 422 `IDEMPOTENCY_KEY_REUSED`.\nOperations marked `x-idempotency: webhook-payload-dedup` instead deduplicate the\nsame webhook id + identical raw body for 60 seconds; they do not accept an\nIdempotency-Key.\n\n## Clients & MCP\n\nUse the HTTP API directly from any language. Official TypeScript and Python SDKs\nare not currently published; generate a client from this OpenAPI document if needed.\n- MCP server: `npx -y @coasty/mcp` (see `x-mcp-server`)\n\n## Reference\n\nComplete (machine-readable) spec is hosted at `/.well-known/openapi.json` and\n`/openapi.json` (Stripe / Vercel conventions)." contact: name: Coasty Developer Support url: https://coasty.ai/support email: founders@coasty.ai license: name: MIT identifier: MIT termsOfService: https://coasty.ai/terms servers: - url: https://coasty.ai description: Production - url: https://coasty.ai description: Sandbox — use sk-coasty-test-* keys against the same host.
