This section contains a description of rate limits and file upload specifications.
deAPI is engineered for High Throughput capability upon deployment. Unlike traditional providers, API scalability is not restricted by complex access levels during the initial integration phase.
Account Types
All new accounts start as Basic and can upgrade to Premium by making any payment.
| Type | Qualification |
|---|
| Basic | New accounts (no payments made) |
| Premium | Any payment made via Stripe |
Upon registration, you receive a $5 bonus added to your balance. This bonus is available for Basic accounts with conservative rate limits designed for testing and evaluation.To upgrade to Premium (300 RPM, unlimited daily requests), simply top up your account with any available amount. Your remaining bonus balance carries over — for example, if you use $2 of your bonus and then purchase $10, your total balance becomes $13 ($3 remaining + $10 purchased), now usable with Premium limits.
Accounts registered with temporary or disposable email addresses do not receive the $5 bonus. We value long-term users and honest usage.
Rate Limits
Rate limits are defined per endpoint as:
- RPM — Requests Per Minute
- RPD — Requests Per Day
Limits reset daily at midnight UTC.
Basic Limits
Basic accounts have conservative limits designed for testing and evaluation.

Endpoints Without Rate Limits
The following endpoints have no rate limits for all accounts:
- Utilities —
/api/v2/account/balance, /api/v2/models
Basic vs Premium Comparison
| Aspect | Basic | Premium |
|---|
| RPM Limits | 1–10 RPM | 300 RPM (all endpoints) |
| Daily Limits (RPD) | Limited | Unlimited |
| Transcription Limit | 1 unified endpoint (v2) | 300 RPM (v2) |
| Upgrade Requirement | — | Any payment via Stripe |
deAPI vs. Traditional Providers
Many AI infrastructure providers enforce restrictive initial limits, necessitating complex queue management systems for developers.
Getting Started
- Traditional Providers: Often require credit card verification or initial payment before any API access.
- deAPI: Immediate access with $5 bonus upon registration — no payment required to start testing.
Scaling to Production
- Traditional Providers: Typically require specific monetary spend thresholds (e.g., $50+) and time delays (weeks/months) to unlock higher rate limits.
- deAPI: Instant upgrade to Premium (300 RPM, unlimited daily requests) with any available top-up amount ($10, $25, or $50).
Limit Structure
- Traditional Providers: Often utilize separate quotas for tokens (TPM), requests (RPM), daily limits (RPD), and per-model restrictions.
- deAPI Premium: Simple unified structure — 300 RPM across all endpoints with unlimited daily requests.

File Uploads
The majority of endpoints (Video-to-Text, Audio-to-Text, Image-to-Image) support direct binary file uploads or URL-based inputs. The global limits for file uploads are specified below.
Global Request & Response Caps
These caps apply to every endpoint regardless of media type. Exceeding them returns 413 Payload Too Large.
| Cap | Limit | Scope |
|---|
| Request body (input) | 75 MB | Total size of any single API request (multipart upload + JSON fields combined) |
| Job result (output) | 100 MB | Maximum size of the generated artifact returned by a worker job |
Per-type caps below are always ≤ the global 75 MB request body cap. If you send multiple files in one request, the sum must still fit within 75 MB.
Per-Type Upload Limits
1. Video (Video-to-Text, Image-to-Video, Video Upscale, Video Replace, Video Background Removal)
- Max size: 50 MB
- Supported Formats: MP4, MPEG, QuickTime (MOV), AVI, WMV, OGG
2. Audio (Audio-to-Text, Voice Cloning reference audio, Audio-to-Video, Music reference audio)
- Max size: 20 MB
- Supported Formats: AAC, MP3, OGG, WAV, WebM, FLAC
- Voice Cloning reference audio: max 15 MB, 3–10 seconds duration. Supported formats: MP3, WAV, FLAC, OGG, M4A.
- Audio-to-Video conditioning audio: max 20 MB. Supported formats: MP3, WAV, OGG, FLAC.
- Music reference audio (style transfer): max 15 MB. Supported formats: MP3, WAV, FLAC, OGG, M4A.
3. Images (Image-to-Image, OCR, Background Removal, Upscale, Image-to-Video first/last frame, Reference Character)
- Max size: 10 MB
- Supported Formats: JPG, JPEG, PNG, GIF, BMP, WebP
- Dimensions: min 64 px, max 5000 px per side
For larger source media that won’t fit under the request body cap, prefer URL-based inputs (source_url / video_url / audio_url) where supported — they bypass the upload cap entirely and are subject only to the duration limits listed below.
Model Parameter Limits
Certain parameters — such as maximum character count, image resolution, frame count, or audio duration — are model-specific and may differ between models available on the same endpoint.
These limits are returned dynamically via the Models endpoint:
GET https://api.deapi.ai/api/v2/models
limits field in each model object to see the applicable constraints before submitting a request. This ensures your inputs stay within the accepted bounds for the specific model you’re using.
For endpoints processing content via direct URLs (e.g., X Spaces), specific duration limits apply regardless of file size.
1. Audio-to-Text (X/Twitter Spaces)
- Max Duration: 600 minutes
- Note: Processing speeds for X Spaces may vary due to external bandwidth limits.
2. Video-to-Text (X, Kick, Twitch)
- Max Duration: 600 minutes
Rate Limit Errors
When you exceed your rate limit, the API returns a 429 Too Many Requests response.
How to handle:
- RPM exceeded — Wait 60 seconds before retrying
- RPD exceeded — Wait until midnight UTC for daily reset
- Need higher limits? — Upgrade to Premium with any payment for 300 RPM and unlimited daily requests
