Pricing

Pay for tokens. Nothing else.

No per-seat licence, no minimum commitment, no charge for the seats that only read dashboards. A modest platform fee buys throughput and support; everything else is usage, billed to the token in arrears.

Start on the free tier

Estimates exclude VAT and embedding costs at index time. Your first month is capped automatically — you cannot overspend by accident.

Included everywhere

Not upsells. Just the product.

Your data stays yours

Nothing you send is used to train a model, on any plan, including the free one. Zero-retention mode is a single flag.

Usage you can see

Cost per run, per key and per collection, live. Export the raw ledger as CSV whenever finance asks where the money went.

Caps that actually stop

Set a monthly ceiling and Lumen refuses new runs past it. No overage invoice, no apologetic email from us.

Fine print

Questions people ask before paying

How is a token counted?

A token is roughly four characters of English, or about ¾ of a word. We count both directions: the text you send and the text the model generates.

Tool definitions, system prompts and retrieved passages are input tokens too. That surprises people, which is why the calculator above asks for total input rather than just your prompt.

What happens when I hit my budget cap?

New runs return 429 budget_exceeded and nothing is billed beyond the cap. Runs already in flight finish normally so you never get a half-written answer.

You can raise or remove the cap instantly from settings, and alerts fire at 50%, 80% and 100% by default.

Do you charge for retrieval?

Embedding at index time is billed per token on lumen-embed — €0.06 per million, so indexing a 500-page handbook costs under a cent.

Queries against an existing index are free. The passages that come back are billed as input tokens on the run that used them.

Can I switch plans mid-month?

Yes, both directions, and the platform fee is prorated to the day. Usage credit is prorated the same way, so upgrading mid-month never costs you the credit you already had.

Is there an annual discount?

Two months free on annual platform fees. Usage stays monthly in arrears at the same per-token rate — we will not ask you to pre-buy credits that expire.

What counts as a “request” for rate limits?

One call to POST /v1/runs, however many tool calls happen inside it. An agent that makes nine tool calls and streams for forty seconds is still one request.

Do you have a startup or non-profit programme?

Registered non-profits and companies under two years old with less than €2M raised get €5,000 of credit and Scale-tier limits for twelve months. One short form, no pitch deck.

How do I cancel?

One button in settings, effective at the end of the billing period, no retention call. Export your collections and run history first — both stay available for 30 days after you leave.

Start free, upgrade when it hurts

Five million tokens a month is genuinely enough to launch something small. When it is not, the next step is €49.
