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.

Reference Uploads

media inputs

Media inputs accept any public URL. To use a local file, POST its content_type and size_bytes to /v1/media/uploads, PUT the file to the returned upload_url, then pass the url.

upload
# 1. Request a presigned upload URL. Send the file's content
#    type and its exact size in bytes.
curl -X POST https://api.dev.pika.art/v1/media/uploads \
  -H "X-API-Key: YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"content_type": "image/png", "size_bytes": 12345}'


# The response returns two URLs:
#   upload_url: a temporary URL to upload the file to. Expires in 5 minutes.
#   url:        the permanent Pika URL. Pass it to the model as the input.
# {
#   "upload_url": "https://upload.r2.pika.art/...?X-Amz-Signature=...",
#   "url": "https://cdn.pika.art/v2/media/uploads/org_abc/9f8e7d.png"

Studio light refracts through the growing glass so specular highlights and caustics shimmer and travel across the petals; plums and green grapes settle gently on the dark reflective table, deep green backdrop. Sound: delicate crystalline glass chimes and soft ringing tones as the flowers grow, gentle airy ambient pad, faint tabletop settle. Elegant glossy candy surrealism, rich saturated color, crisp studio light, smooth organic growth motion, no morphing artifacts.",

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"}}
