Gengo

Gengo is a people-powered translation platform that delivers fast, affordable, high-quality human translation in every major language through a global network of thousands of certified translators. The Gengo API (v2) lets developers order translation programmatically: submit text or file jobs, group them into orders, run cost quotes, look up supported language pairs and tiers, manage glossaries, retrieve completed translations and revisions, exchange comments with translators, and receive job-status updates through per-job callback URLs. Authentication uses a public API key plus an HMAC-SHA1 request signature, with a full sandbox for testing. Gengo was surfaced as a portfolio company of 500 Global and Point Nine and enriched into the API Evangelist network.

Gengo publishes 6 APIs on the APIs.io network, including Account API, Glossary API, Job API, and 3 more. Tagged areas include Company, Translation, Localization, Human Translation, and Language Services.

The Gengo catalog on APIs.io includes 1 event-driven AsyncAPI specification.

Gengo’s developer surface includes documentation, API reference, getting-started guide, support, engineering blog, pricing, signup flow, and 20 more developer resources.
