PRICING · PRICED BELOW THE HYPERSCALERS

Start free. Pay for volume,
not per model call.

Every account begins in Test mode — 100 free calls to wire up the API. Upgrade when you ship. Our marginal cost is compute, so the per-call price is a fraction of hosted moderation APIs.

Billing is metered on filter calls; 1 call = one POST /v1/filter or one item in a batch. Overage is billed monthly or you can hard-cap at your quota. Prices in USD.

Pricing questions

What counts as a "call"?
One POST /v1/filter, or one item inside a batch request. Health checks and metrics don't count.
What happens after 100 test calls?
Your test key keeps working for verdicts on our sample corpus; add a card to mint a live key and lift the cap.
Do you throttle or overage?
Your choice per key — hard-cap at quota (429 with Retry-After) or auto-overage at the per-100K rate.
Can I self-host?
Filter8 is a managed, hosted API today — self-hosted deployment isn't available yet.
