Deepgram: $200 Free Credit on Sign-Up
Deepgram
The first tier on the pricing page is labeled "Free $200 Credit", after which it switches to pay-as-you-go (Pay-As-You-Go); the credit can be used for speech transcription, speech synthesis, and Voice Agent
Verbatim from the first tier on the official pricing page: "Free $200 Credit, then pay-as-you-go"; the FAQ has a question "What is included in the $200 free credit?" (the answer is collapsed and could not be read on the page). The pricing page also lists pay-as-you-go prices for the Voice Agent API and speech synthesis; there is also a "spend as much, get as much" promotion for Flux TTS (every $1 spent earns $1 extra, up to $500, ending 2026-12-31), which is a paid promotion and is not counted in this entry's free credit.
The credit's validity period, whether a card is required, and which products the free credit covers exactly could not be read because the official FAQ answer is collapsed, and none of these have been verified, so read the sign-up page notes before claiming. Reachability from mainland China was not tested.
