Production fallback Keep at least one compatible backup provider before shipping

Production readiness checklist

Quota gate Start inside Free via platforms; log usage before adding retries or batch jobs.

No-card check Try the free path first, then confirm whether billing is required for API keys, higher RPM, or production endpoints.

Regional smoke test Run signup, dashboard, DNS, TLS, and first API call checks from mainland China before launch.

Python setup snapshot

Start with the smallest possible chat completion, then move the key to your server-side secret manager before production.

import fal_client
result = fal_client.subscribe("fal-ai/flux/dev",
    arguments={"prompt": "A beautiful sunset over mountains", "image_size": "landscape_16_9"})
print(result["images"][0]["url"])

Free API and pricing notes

Free via Replicate/HuggingFace and other platforms

Access and production risk

Relay or proxy may be needed

API platforms need proxy. Local deployment needs no network. ComfyUI is best local option.

How to set it up

Create or locate your provider API key in the official dashboard.

Install the provider SDK or requests dependency shown in the example.

Set the API key in an environment variable instead of hard-coding secrets.

Run a small FLUX (Black Forest Labs) chat completion with FLUX.1 [schnell].

Watch free credits, RPM/TPM limits, response shape, and error messages before scaling.
