| Free tier | none: the hosted API at libretranslate.com needs a paid API key (Pro USD 29 a month, Business USD 58 a month); the vendor offers no free trial and no free low-volume key unit none; metered on none; the keyless GET /frontend/settings of the hosted service reports keyRequired true, so the hosted translate endpoint refuses callers without a key. A 7 day money-back guarantee exists on the paid plans |

| Price | none stated |

| Limits | - per-object-cap 2,000 characters per request source
- request-rate bursts of up to 80 translations / minute on Pro; 200 translations / minute on Business; translations are unlimited source
|
|---|
| Binding | none no free allowance exists to bind; the paid key is the gate, and the 2,000 character request size is the only per-call cap |
|---|
| Identity | card (inferred, not read) the keys are bought through Stripe checkout links on the portal page; the checkout page was not opened, so that the payment method is a card is inferred from the Stripe checkout and unverified |
|---|
| Egress | not published |
|---|
| Per-object cap | 2,000 characters per request (the hosted service's charLimit setting) |
|---|
| Retention | not applicable: a translation endpoint stores nothing for the caller |
|---|
| Interface | rest |
|---|
| Tooling | REST API: POST https://libretranslate.com/translate with q, source, target and api_key. Hosted offer first: the paid Pro and Business keys; self-hosted option last: the user installs and runs the open-source server (pip install libretranslate) on a rented or free machine, which is not what this record prices |
|---|
| Composes with | none: no free allowance to chain; the self-hosted option is the free route and ranks after every hosted offer |
|---|
| Reliability | a single hosted operator; the vendor states that a free low-volume key was tried in the past and stopped as not sustainable |
|---|
| Notes | Supported languages: GET /languages answers without a key and lists language codes from en to vi, among them sq, ar, zh-Hans, zh-Hant, pt-BR, ru and uk (the list is longer than the language names that the home page menu shows). Character limit per request: 2,000. Keyless: no; the web page loads without a key but the translate API reports keyRequired true. |
|---|
| Evidence note | documented the price, the absence of a free tier or trial and the request rates are quoted from the vendor's portal; the 2,000 character limit and the key requirement are read from the service's own settings endpoint; the payment method of the checkout is unverified. |
