API Developer, where the free key signup leads, allows 1,000,000 characters in total with no card, and it never resets. API Growth is a monthly or yearly subscription with 1 million characters a month included (12 million a year), pay as you go above that, capped at 50 million characters and 300 speech-to-text hours a month. I couldn't read the per-character rates because the pricing page renders only in a browser, and the Growth subscription price isn't in what I read either. The billing rules are clearer. Every source character counts, spaces included, tags don't with tag handling on, a text sent with the same source and target language still bills, and Word, PowerPoint, Excel and PDF files bill at least 50,000 characters each. Failed-call billing is unchecked. Two because the free route is a one-off and the price past it couldn't be read.

For a defensible translation that's the control an agent wants, since a glossary is a citable reason a term came out the way it did, and the response returns the detected language. The reference is the most complete of the seven translation listings I read, an OpenAPI document with 43 paths synced daily, llms.txt with about 180 links and a keyless docs MCP server. The error page says to retry 429 and 529 with backoff and to stop on 456. Two things to know. A text sent with the same source and target language is still billed. The privacy policy doesn't say whether API Developer text counts as free-service content that may train models. Five, because the answer comes with its terminology and register on record.
