Price before you submit
For image generation, the recommended flow is to ask for the credit estimate first, then create the task only when the returned cost is acceptable.
Bash
curl -X POST "https://api.cheapaiapi.com/v1i/task/price" \

}'Task-based checks
Image generation
Model-specific and parameter-specific. Call the price endpoint before creating the task.
POST /v1i/task/price
Text to speech
Charged by request content and model family. Premium and turbo models can differ.
POST /v1/text-to-speech/:voice_id or POST /v1m/task/text-to-speech
Speech to text
Task-based. Submit the file once, then poll the common task endpoint.
POST /v1/task/speech-to-text
Music and sound effects
Generation costs depend on the task type and requested output.
POST /v1m/task/music-generation or POST /v1/task/sound-effect
What users should expect
One balance
All supported voice, audio, music, and image tasks draw from the same credit pool.
Price checks where it matters
Image generation exposes a dedicated price endpoint, which is the safest way to show cost before task creation.
API key controls
Create up to three active API keys, then apply expiration and daily spend caps per key.
