Authenticate with `Authorization: Bearer vy_live_…`. Every response carries `X-Request-ID` and the `X-RateLimit-Limit` / `X-RateLimit-Remaining` / `X-RateLimit-Reset` (seconds until the window resets) headers; a 429 adds `Retry-After`. Errors share one envelope (`ErrorResponse`). version: 1.0.0 x-voyager-agent-prompt: > Set up the Voyager API in this project. Voyager generates images, video, speech, music, sound effects, 3D and object masks with the same models and credits as the Voyager app. Docs: https://docs.voyager.so/api (agent-readable: https://docs.voyager.so/llms.txt, OpenAPI: https://api.voyager.so/v1/openapi.json) 1. Key: read it from the env var VOYAGER_API_KEY. Never hard-code it or commit it; add VOYAGER_API_KEY= to .env.example and make sure .env is git-ignored. If it's missing, ask me to create one at https://voyager.so/dashboard/api (paid plans). 2. Base URL https://api.voyager.so/v1, header: Authorization: Bearer $VOYAGER_API_KEY 3. Pick a model: GET /models?type=image|video|speech|music|sound_effect|3d|segment. Read GET /models/{id} for its input_schema before building a request. 4. Optional cost check: POST /estimate with the same body as step 5; it returns estimated_charge (credits) and can_run. 5. Create: POST /jobs {"model": "", "operation": "", "input": {...}} with an Idempotency-Key header (a new UUID per logical request; reuse it when retrying the same request). 6. Wait: GET /jobs/{id}?wait=25 until status is succeeded, failed or canceled (honor Retry-After / poll_after_ms). Or pass "webhook_url" and verify the Standard Webhooks signature with the secret from the dashboard. 7. Results: job.outputs[].url is a signed link valid for 1 hour; download it right away, or GET /jobs/{id} again for a fresh link. Files are kept 30 days. 8. Errors are {"error": {"code","message","retryable",...}}. 402 = out of credits or not on a paid plan (show error.details.upgrade_url to me). 429 = slow down: wait Retry-After seconds. Retry only when retryable is true, with the same Idempotency-Key. Minimal example (curl): curl -s https://api.voyager.so/v1/jobs \ -H "Authorization: Bearer $VOYAGER_API_KEY" -H "Content-Type: application/json" \ -H "Idempotency-Key: $(uuidgen)" \ -d '{"model":"nano-banana-2.1","operation":"text-to-image","input":{"prompt":"a red fox in snow","aspect_ratio":"16:9"}}' curl -s "https://api.voyager.so/v1/jobs/?wait=25" -H "Authorization: Bearer $VOYAGER_API_KEY" Write a small typed client (create → wait → download) with retries as above, then generate one test image to prove it works and tell me what it cost (job.credits.charged; if credits.state is still "pending", report job.credits.estimated and say it's an estimate). servers: - url: https://api.voyager.so/v1 description: Production security: [] paths: /cast/{cast_id}: get: tags: - Cast summary: Get a Cast card description: One card by id (cst_…) or slug, with fresh links to its references. operationId: getCast parameters: - name: cast_id in: path required: true schema: type: string title: Cast Id responses: '200': description: Successful Response content: application/json: schema: $ref: '#/components/schemas/Cast' headers: X-Request-ID: $ref: '#/components/headers/X-Request-ID' X-RateLimit-Limit: $ref: '#/components/headers/X-RateLimit-Limit' X-RateLimit-Remaining: $ref: '#/components/headers/X-RateLimit-Remaining' X-RateLimit-Reset: $ref: '#/components/headers/X-RateLimit-Reset' '401': description: Missing, invalid or revoked API key. content: application/json: schema: $ref: '#/components/schemas/ErrorResponse' headers: X-Request-ID: $ref: '#/components/headers/X-Request-ID' X-RateLimit-Limit: $ref: '#/components/headers/X-RateLimit-Limit' X-RateLimit-Remaining: $ref: '#/components/headers/X-RateLimit-Remaining' X-RateLimit-Reset: $ref: '#/components/headers/X-RateLimit-Reset' '404': description: Not found in this workspace. content: application/json: schema: $ref: '#/components/schemas/ErrorResponse' headers: X-Request-ID: $ref: '#/components/headers/X-Request-ID' X-RateLimit-Limit: $ref: '#/components/headers/X-RateLimit-Limit' X-RateLimit-Remaining: $ref: '#/components/headers/X-RateLimit-Remaining' X-RateLimit-Reset: $ref: '#/components/headers/X-RateLimit-Reset' '429': description: Rate limited.
