Requirements

→Free Latentface account (no credit card)
→Python 3.9+ or Node 18+

Create your account and copy your key

Sign up at latentface.net. Confirm your email, open the dashboard, and copy your key from API Keys → Default. Free-tier keys work immediately with 100 calls/day.

Tip: Keep your key in an env var. Never commit it to a repo.

Install the SDK

Python: `pip install latentface`. TypeScript: `npm install @latentface/sdk`. Both SDKs expose the same call surface.

Authenticate

The SDK reads `LATENTFACE_API_KEY` from the environment automatically, or pass `api_key="lf_..."` to the client constructor.

Make your first call

Call `client.embed(image="./face.jpg")` — the response is a 512-dim float32 vector you can store in any vector DB.

Tip: Every endpoint has a runnable curl example in the docs if you prefer to inspect the raw response first.

Check your usage

The dashboard shows per-key call counts, p50/p95 latency, and the current billing-cycle spend. Export to CSV any time.
