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.
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

Generation & Transformation EndpoinGeneration & Transformation Endpoints

In v2 transcription is unified into a single endpoint (/api/v2/audio/transcriptions) — the Whisper shared-limit across 4 v1 endpoints no longer applies.

​
Utility Endpoints

​
Premium Limits

Premium accounts have high limits suitable for production workloads. All endpoints share a unified 300 RPM with unlimited daily requests.
In v2 Whisper is a single endpoint (/api/v2/audio/transcriptions) with its own 300 RPM allocation.

​
Endpoints Without Rate Limits

The following endpoints have no rate limits for all accounts:
  • Utilities — /api/v2/account/balance, /api/v2/models

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.

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.

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 CapGlobal Request & Response Caps

These caps apply to every endpoint regardless of media type. Exceeding them returns 413 Payload Too Largese caps apply to every endpoint regardless of media type. Exceeding them returns 413 Payload Too Large.
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

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
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:

​
URL Input & Duration Limits

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.

​
Rate Limit Errors

When you exceed your rate limit, the API returns a 429 Too Many Requests response. How to handle:
  1. RPM exceeded — Wait 60 seconds before retrying
  2. RPD exceeded — Wait until midnight UTC for daily reset
  3. Need higher limits? — Upgrade to Premium with any payment for 300 RPM and unlimited daily requests
