FLUX 3 Text To Video

FLUX 3 text-to-video, 5-20s with native audio, billed per second of generated video at 720p or 1080p. Draft mode is a cheaper 720p-only preview that can be re-rendered at full quality.

Capabilities

Best for

  • Cinematic text-to-video shots
  • Short social and ad clips
  • Consistent multi-shot sequences
  • Look-dev and style exploration

Not for

  • Frame-exact rotoscoping
  • Feature-length renders
  • Pixel-perfect compositing
  • Precise on-screen text

Authentication

api key header

The Pika API uses API keys to authenticate requests. Send your key in the X-API-Key header. Your API key is a secret. Don't expose it in browsers or other client-side code. Instead, call the API from your server. The signed-in playground uses a portal session and never sends your API key.

REST Setup

Errors

shared across calls

Errors use conventional HTTP status codes with a JSON body of the shape {"message": "..."}. Validation failures return 422 with a message naming the offending field. Submit rejections after the job row exists (balance, rate limit) return the failed job envelope — branch on error.code.

StatusWhenBody
401 UnauthorizedThe API key is missing or invalid.{"message":"Invalid API key"}
403 ForbiddenAn inactive key is rejected with a `{"message"}` body. A submit that the org balance or postpaid cycle limit cannot cover is rejected after the job row exists and returns the failed job envelope.{"id":"media_8f3a2c91-5b7d-4e0a-9c26-31d4f2a8e6b0","status":"failed","error":{"code":"insufficient_balance","message":"Insufficient org balance"}}
404 Not FoundNo job with that id exists in your org, or the media path names an unknown vendor/model/function.{"message":"media job not found"}
409 ConflictThe result was requested before the job completed, or an Idempotency-Key header was reused with a different body.{"message":"media job is not ready"}
422 Unprocessable EntityThe request body failed validation: an invalid enum value, a missing required field, a wrong type, or malformed JSON. The JSON message names the offending field. A schema-valid parameter combination that cannot be priced instead fails after job creation and returns the failed job envelope with error code `invalid_input`.{"message":"duration: Input should be less than or equal to 15"}
429 Too Many RequestsOrg limit reached: requests per minute or day, or concurrent jobs. Returned as the failed job envelope; check the Retry-After header and retry with a fresh Idempotency-Key.{"id":"media_8f3a2c91-5b7d-4e0a-9c26-31d4f2a8e6b0","status":"failed","error":{"code":"rate_limited","message":"rate limit exceeded: rpm"}}
503 Service UnavailableThe model rail or a backend dependency is temporarily unavailable. Returned as the failed job envelope; retry with backoff and a fresh Idempotency-Key.{"id":"media_8f3a2c91-5b7d-4e0a-9c26-31d4f2a8e6b0","status":"failed","error":{"code":"provider_unavailable","message":"media dispatch unavailable"}}
