Speech-to-text and text-to-speech API — $200 free credits on signup (no credit card required), ~43K minutes transcription with Nova model, credits never expire. Access to all model endpoints
- Deepgram's docs say only data included through its Model Improvement Partnership Program is stored and used for future model training. Adding mip_opt_out=true to a request excludes it, and opted-out request data is kept only while the request is processed. (From developers.deepgram.com/docs/the-deepgram-model-improvement-partnership-program, read 2026-10-23.)
- Nova-3 speech-to-text allows up to 50 concurrent pre-recorded requests and up to 150 concurrent streaming requests. (From developers.deepgram.com/reference/api-rate-limits, read 2026-10-23.)
- A transcription request without enough credits fails with HTTP 402 Payment Required, with the message "Project does not have enough credits for an ASR request and does not have an overage agreement." (From developers.deepgram.com/docs/errors, read 2026-10-23.)
- Rate limits apply per project, not per account or API key. Creating additional projects under the same account does not grant additional concurrency. Secondary projects on a self-serve account are limited to a single concurrent stream. Using additional projects or accounts to work around the limits is detected and violates Deepgram's Terms of Service. (From developers.deepgram.com/reference/api-rate-limits, read 2026-11-07.)
- Deepgram's terms, section 2.4, forbid use of the Services or any Output "for competitive purposes, including model training, benchmarking and other competitive analysis, or developing competing models, products or services". (From deepgram.com/terms, read 2026-11-07.)
- Deepgram's terms, section 2.4, prohibit resale or redistribution of the Services on a stand-alone basis. Integration into the user's own Application is allowed when the Application contributes material independent functionality beyond Deepgram's Services. (From deepgram.com/terms, read 2026-11-07.)
