Tools: 1

Keyless machine + translation-memory translation between languages — the one translation pack in the catalog that needs no API key, no self-hosted instance, and no registration of any kind.

Tools

• mymemory_translate(text, target, source?) — translates text into target (ISO 639-1, e.g. "de"). source is optional and defaults to automatic language detection; when it auto-detects, the detected code comes back in detected_source_language. Also returns a match-quality score (1.0 = an exact translation-memory match, lower = machine-translated) and up to 3 alternate candidate translations.

Auth

Keyless. Every call carries a courtesy contact address (not a login, not a key) that raises the shared anonymous allowance under the publisher’s own usage policy — see “Quota” below.

Data sources

• MyMemory (Translated S.r.l.), a community and machine translation memory — translations contributed by professional translators, public corpora and machine translation, blended and ranked by match quality.

Quota

Free, anonymous use is limited by the publisher to 5,000 characters/day, raised to 50,000 characters/day by supplying a contact address (which this pack does on every call). All Pipeworx gateway traffic shares one egress address, so this allowance is shared across every caller of this pack — exactly like the SEC.gov egress note elsewhere in this repo. When the shared daily allowance is spent, the tool returns a clear {found: false, reason: "rate_limit"} refusal rather than retrying or rotating identity; it resets on the publisher’s own rolling daily window, not ours.

Why this exists

deepl needs a funded platform key (unfunded by choice) and its shared key also runs on a monthly character allowance that has sat exhausted for extended stretches. translate and libretranslate both wrap LibreTranslate, which needs either a key or a self-hosted endpoint since the free public mirrors shut down in 2025-26. That left no translation tool anyone without a key of their own could actually use — this pack is that tool (fleet #3862).

Both of those packs’ refusals now name mymemory_translate as the keyless alternative, and the gateway’s sibling-retry (NAMED_SERVICE_SIBLING_OVERRIDE in workers/gateway/src/retry-policy.ts) falls over to it automatically when deepl_translate fails on a quota-exhausted shared key — the source/source_lang and target/target_lang field-alias families in shared/src/field-aliases.ts are what let the retry hand this pack the same arguments the failed call received.

Tools

• mymemory_translate — Translate text from one language to another with no API key required. Source defaults to automatic language detection when omitted. Returns the translated text, the detected source language (when auto
