Official clients for Python and JavaScript: one method per endpoint, retries on rate limits, paging and streaming built in. No dependencies.

• Both read your key from TRADYTICS_API_KEY, or take it as Client(api_key=...) and new Tradytics({ apiKey }).
• Answers are the API's JSON as it comes: data and as_of for objects, data, count and next_cursor for lists. Every endpoint page shows its call in both.
• stream polls options flow or dark pool prints with since and yields each new print once, oldest first.
• A failed call raises TradyticsError with status, code, message and the request id. 429 and 5xx answers are retried up to three times, waiting as Retry-After says; the daily quota is not retried.
