One glossary, two ways in: a flat-price workspace for people, a pay-per-use API for software. Try it first with the demo on the homepage: paste a text, no signup.

What counts as an operation?
Developer API requests are priced by what they return, so cost tracks value and nothing else. The table is short:
| Request | Cost |
|---|---|
POST /v1/translate | 1 operation per term match found |
GET /v1/term/:id | 1 operation per card section returned (a full card is typically 7 to 9) |
POST /phase3 | the term matches, plus 0 to 3 operations per distinct term embedded, by grounding level |
GET /v1/usage | free |
Text where we find nothing costs nothing, and refused requests (bad input, over a size limit) are never charged. The docs spell out every case with worked examples.
No overage on Workspace, ever. If you reach your monthly limit, requests pause until the next period. Your bill never surprises you.
No meter games on Developer. Every response tells you what it just cost (
opsBilled), and your running total with an estimated cost is one free call away.Cancel yourself, any time. Billing runs through a self-serve portal: no phone calls, no "retention specialist".
Plain answers
- How do I try it before paying?
- The demo on the homepage: paste up to 1,500 characters and see every known term explained, no signup, 5 texts an hour. Building an integration? The evaluation kit in the docs carries a real term card, the full field schema, and an OpenAPI spec, downloadable without an account.
- What counts against the Workspace monthly total?
- Every term match in text you send. A term that appears three times counts three times: each occurrence is found, positioned, and explained in place. The response's
matchCountis exactly what you spent, and text where nothing is found costs nothing. Checking your usage and opening term detail cards are free and unmetered on Workspace. - Is the Developer API a subscription?
- There's no monthly fee and no minimum: you're billed once a month for the operations you used, from the first one. In the billing portal it appears as a monthly plan you can cancel any time; a month with no usage bills nothing.
- Do you store my input?
- No. Your text is processed and returned. It is never stored, and it never travels to a third-party AI. More on trust & security.
- How do I get my API key?
- It's shown once, right after checkout. We store only a fingerprint of it, so save it somewhere safe. You can roll it (replace it with a new one) from your account page any time.
