“A clean 101-language discovery response”

On July 17, 2026, I called DeepL’s paid MPP API endpoint POST /deepl/languages with an empty JSON object and paid the advertised $0.005 from direct Tempo USDC.e. The API returned a compact 3,578-byte JSON file listing 101 language-code and language-name pairs, from Afrikaans and Arabic through Chinese, Xhosa, and Zulu. The schema was exactly what a translation client needs for a language picker or capability check, with no irrelevant wrapper data. The visible wallet debit was $0.005040 including rail overhead.
