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
plain HTTPS
Video generation runs through the REST endpoint shown above. The API is plain JSON over HTTPS, so any HTTP client works. No provider-specific SDK is required.

ONE continuous unbroken take, no cuts. The camera moves constantly but always smoothly, on a crane and dolly — long fluid arcs, motivated reframes, no handheld shake, no whip pans, no speed ramps. Scene: a bare lilac room — lilac walls, lilac wool carpet, white baseboard, a long sheer lilac curtain at the left of frame. In the centre stands an ironing board with pale lilac legs and a lilac cotton cover. Draped over it is one large square silk scarf printed in dusty rose pink and olive green, a fine botanical pattern with a broad olive border: the left half lies perfectly flat and pressed with its edge hanging crisply over the rounded nose, the right half gathered into a soft billowing heap spilling over the far end. A wide polished chrome cuff bracelet stands upright on the pressed section, mirror-finish, warping the pink and lilac around it. A fine silver chain lies beside it and trails off the left edge, pooling on the carpet. Action: the curtain swells inward as a draught enters the room. The gathered folds on the right stir, then begin to rise — the silk lifting off the board and unfurling itself, opening out into a full square that floats and turns in the air above the ironing board, the printed botanicals rippling as it revolves. The loosened chain slides off the edge and drops to the carpet in a bright coil. The chrome cuff rocks, topples onto its side and rolls slowly along the bare lilac board cover toward the nose, reflections spinning across it. The silk keeps rising, drifting toward the window and the curtain, then falls all at once, settling flat across the empty board exactly as it was pressed at the start. Camera: begin low and close on the chrome cuff, the pressed silk and the hanging chain, then rise and arc left around the nose of the board as the curtain moves. As the silk lifts, crane upward with it, turning to follow the scarf as it revolves in the air, holding it centred while the lilac room rotates behind. Descend with the falling chain in one continuous move, level out into a low tracking shot beside the rolling cuff, then crane back up and pull out into a wide, symmetrical frontal of the board just as the silk settles onto it. Look: soft diffuse daylight through the curtain, no hard shadows, a tight palette of lilac, dusty pink and olive. Shot on 35mm film, 80mm lens, medium depth of field, fine natural grain, low contrast, liquid sheen on the silk. Photographic and physically real, like an Hermès still-life campaign — no digital gloss. The room is empty; there is no iron and no person. Audio: quiet room tone, a curtain drawing against the wall, silk snapping open and rustling as it turns in the air, a chain dropping onto carpet, chrome rolling on padded cloth, the soft whump of fabric landing, nothing else.","duration": 10,"resolution": "720p","generate_audio": true,"watermark": false,"ratio": "16:9"}'

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.
| Status | When | Body |
|---|---|---|
| 401 Unauthorized | The API key is missing or invalid. | {"message":"Invalid API key"} |
| 403 Forbidden | An 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. `GET /billing/balance` separates the two: a `200` means the key is active, so the rejection was the balance or the cycle limit. | {"id":"media_8f3a2c91-5b7d-4e0a-9c26-31d4f2a8e6b0","status":"failed","error":{"code":"insufficient_balance","message":"Insufficient org balance"}} |
| 404 Not Found | No job with that id exists in your org, or the media path names an unknown vendor/model/function. | {"message":"media job not found"} |
| 409 Conflict | The 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 Entity | The 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 Requests | Org 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 Unavailable | The 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"}} |
