The pricing examples shown on the public site ([https://deapi.ai/#pricing](https://deapi.ai/#pricing)) serve as reference points; final cost is determined by the API at runtime depending on the selected model and parameters. ### Pricing Overview Up-to-date prices are always available via the `/price` endpoint for the selected model (v2) or `/price` (v1). | Task Type | Pricing Metric | Example Rate | Endpoint (v2) | | --------------------------------------- | ----------------------------------- | --------------------------------------------------------- | ----------------------------------------- | | Image Generation (Flux.1 schnell) | resolution × steps | 0.00136 USD for 512x512, 4 steps | `POST /api/v2/images/generations` | | Image Generation (Z-Image-Turbo INT8) | resolution × steps | 0.00405 USD for 512x512, 4 steps | `POST /api/v2/images/generations` | | Image Generation (Flux.2 Klein 4B BF16) | resolution × steps | 0.00186 USD for 512x512, 4 steps | `POST /api/v2/images/generations` | | Image Edit | steps (style transfer) | \~0.0132 USD for 512x512, 20 steps | `POST /api/v2/images/edits` | | Text-to-Speech (TTS) | number of characters | 0.77 USD per 1 M characters | `POST /api/v2/audio/speech` | | Text-to-Music | duration + inference steps | Use `/price` endpoint | `POST /api/v2/audio/music` | | Video Generation | video duration + resolution | 0.001737 USD for 2s, 256×256 | `POST /api/v2/videos/generations` | | Video Animation (Image-to-Video) | source image + motion interpolation | 0.001737 USD for 2s, 256×256 | `POST /api/v2/videos/animations` | | Transcription (URL + file, all sources) | duration | from 0.05 USD per hour | `POST /api/v2/audio/transcriptions` | | Image OCR | output characters | 0.00928 USD per 1,000 output chars (for 1024×1024 images) | `POST /api/v2/images/ocr` | | Embeddings | number of tokens processed | 0.000068 USD per 1,000 tokens | `POST /api/v2/embeddings` | | Image Background Removal | per image | Use `/price` endpoint | `POST /api/v2/images/background-removals` | | Image Upscale | resolution × scale | Use `/price` endpoint | `POST /api/v2/images/upscales` | | Video Replacement | duration × resolution × steps | Use `/price` endpoint | `POST /api/v2/videos/replacements` | | Video Upscale | resolution × duration × scale | Use `/price` endpoint | `POST /api/v2/videos/upscales` | *** ### Pricing by Task **Image Generation** * Users define width, height, steps via the API or UI. * Public example: Flux Schnell model is used to estimate cost in the UI; for example, 512x512 at 4 steps gives **0.00136 USD**. For the Z-Image-Turbo INT8 model with the same parameters, the price is **0.00405 USD**, but the advantage is very realistic images. * Higher resolutions and more steps yield better quality but incur higher cost. * Important: For models other than Flux Schnell, pricing is model-specific and calculated on the server side. **Text-to-Speech (TTS / Speech Generation)** * Charged per character in your input (e.g. 1M characters → **0.77 USD**). * Playback speed modifiers: * Standard (1.0×): base cost * Fast (2.0×): 0.5× the base cost * Slow (0.5×): 2.0× the base cost * Useful tip: using faster playback (2×) for drafts can reduce cost by \~50%. * All three TTS modes (custom\_voice, voice\_clone, voice\_design) use the same per-character pricing model. **Text-to-Music (Music Generation)** * Price depends on track duration (10–600 seconds) and the number of inference steps. * Turbo models use fewer steps (e.g. 8) and are cheaper; base models use more steps (e.g. 32+) for higher quality. * Use the `/price` endpoint with your `model`, `duration`, and `inference_steps` to get exact pricing before generation. **Text-to-Video** * Price depends on clip duration (2–5 seconds) and resolution. * Example public rate: **0.001737 USD** for a 2-second clip at 256x256. * You can scale resolution or duration, but cost increases accordingly. **Image Edit (Image-to-Image)** * Transforms an existing image based on a new prompt or style. * Pricing scales with the number of inference steps and GPU time required — similar to Text-to-Image tasks. * Example: a 20-step transformation costs roughly the same as generating a 512×512 image. * Fewer steps → faster & cheaper transfers; more steps → better fidelity. **Image-to-Video** * Transform a static image into a motion clip (2–5 seconds) with interpolation. * Example: 256x256 for 2 seconds costs **0.001737 USD**. * Use lower resolution or shorter duration to reduce cost. * Use motion parameters in prompts to guide movement. **Video-to-Text (Transcription)** * Billed per hour of video processed. * Sample public rate: **0.05 USD per hour**. * For 5 minutes, cost is estimated at **0.0075 USD**. * Supports timestamps, multilingual transcription, and batching for better throughput. **Image-to-Text (OCR / VLM)** * Charged based on number of characters recognized in output. * Baseline rate: **0.00928 USD** per 1,000 output characters (for 1024×1024 images). * Example outputs: * Single photo (≈20 chars) → **0.000186 USD** * Math expression (\~350 chars) → **0.0032 USD** * Book page (\~1,500 chars) → **0.0139 USD** * Volume discounts available for bulk processing (100k+ images)—contact sales. **Text-to-Embedding (Vector Representations)** * Pricing is based on the number of tokens processed. * Sample public rate: **0.000093 USD** per 1,000 tokens (client-side pricing). * Embeddings are typically used for semantic search, retrieval-augmented generation (RAG), clustering, and similarity matching. * Costs scale linearly with token count, making it efficient even at large volumes. * Important: Different embedding models may have varying dimensionality (e.g. 768 vs. 1024), but pricing is standardized per token for simplicity. **Video Replace (Animate)** * Replaces a character in a video using a reference image. * Price depends on video duration, resolution, and inference steps. * Use the `/api/v2/videos/replacements/price` endpoint with your `model`, `duration` (or upload `video`), `width`, and `height` to get exact pricing. **Video Upscale** * Increases video resolution (e.g. 2×, 4×) using AI super-resolution. * Price scales with input resolution, video duration, and the selected `scale` factor (only for models with configurable scale — fixed-scale models use their built-in factor). * Use the `/api/v2/videos/upscales/price` endpoint with your `model`, `width`, `height`, optional `duration`, and optional `scale` to get exact pricing before uploading the file. *** ### Best Practices & Guidance * Use the public calculator as a guide, but always rely on the API's final cost calculation (model + parameters). * Avoid hardcoding prices or cost assumptions—always fetch or compute cost based on actual model usage. * For reproducibility (e.g. in production or experiments), pin model versions and seeds so results are consistent across runs. * Prepare fallback options in your integration: if a model is deprecated or disabled, switch to a sensible alternative automatically. * Monitor usage and budget: higher resolution, longer clips, or more steps increase costs proportionally. *** **Link to live pricing page for reference:** [https://deapi.ai/pricing](https://deapi.ai/pricing)
