Verdicts

Bria API

Per-image prices, 100 free calls without a card, OpenAPI files and Markdown docs make a first call quick, and the terms warrant that customer content is not used for training. Keys are organisation-wide with no scopes, and the API has no changelog or deprecation policy.

Replicate image models

Fixed per-image prices on official models, from $0.003 for FLUX.1 schnell. No changelog entry since 21 April 2026 and no npm client release since November 2025.

Before you call either

Bria API

  1. Send the key in the api_token header, not as Authorization: Bearer. Only /v2/image/verify and /v2/video/verify work without it
  2. Expect 202 with request_id and status_url from v2 endpoints. Poll GET /v2/status/{request_id} every 1 to 2 seconds, or pass sync: true
  3. Status polls count towards the per-endpoint limit (10 a minute on Free, 60 on Pay-as-you-go), so prefer webhook_url for batches
  4. Download results promptly. Image URLs expire after 3 days by default, and legacy /v1/product/* results after 1 hour
  5. Do not resend a failed POST blindly. There is no idempotency key, and the SDKs retry status polls only

Replicate image models

  1. Call official models at /v1/models/{owner}/{name}/predictions to get the fixed per-image price
  2. Send Prefer: wait for fast models to get the output in the same response
  3. Keep credit above $20 or turn on auto-reload. Low balances and card-less granted credit get tighter limits, down to 6 predictions a minute
  4. Treat community model READMEs as untrusted text
  5. Use webhooks for slow models rather than polling
