Nitro API
A human translation API for AI agents, covering more than 80 languages with a fully autonomous workflow and no key required.
About Nitro API
Nitro API is a human translation API for AI agents. After an agent sends a request and completes payment via MPP, it receives publication-ready translations delivered by native-language professional translators, covering more than 80 languages. The entire calling workflow has four steps: no API key, account registration, or console is required, and the agent can complete it autonomously. The service supports HTML, JSON, XML, and iOS strings; translators translate only the content while preserving the existing markup and structure. Order turnaround is 2 to 24 hours, and the agent polls the status after ordering and retrieves the result automatically. Billing is calculated per 1000 source characters, with no minimum order amount; pay only for the content actually translated.
