YepAPI Free $5 Credit

Offer Overview

YepAPI provides $5 in free credit immediately upon registration with no credit card required. The credit gives complete programmatic access to over 200 AI models spanning text generation, multimodal reasoning, image creation, text-to-speech, and video generation through a single unified API.

In addition to the $5 signup balance, YepAPI hosts completely free-to-query models such as NVIDIA's Nemotron 3 Super ($0.00 per million tokens) and Fish Audio S2.1 Pro Free for voice prototyping.

What the $5 Free Credit Covers

Because YepAPI bills strictly pay-per-token with no subscriptions or monthly minimums, a $5 grant provides significant throughput across lightweight and reasoning models:

• DeepSeek Models: Thousands of queries across DeepSeek V3, DeepSeek V4 Flash, and DeepSeek R1 reasoning models (starting around $0.20 to $0.38 per million input tokens).
• Open-Source Architectures: High-volume experimentation with Meta Llama 4 Scout, Llama 4 Maverick, and Alibaba Qwen 3.5 variants (Llama 4 Scout and Maverick at $0.22 per million input tokens).
• Frontier Flagships: Immediate testing on GPT-5.4, GPT-4o, Claude 4 Sonnet/Opus, and Gemini 2.5/3.1 without purchasing separate vendor commitments.
• Multimodal Generation: Testing image generation models (FLUX.2, GPT Image, Recraft) and video generation pipelines (Veo 3.1, Wan 2.6, Hailuo).

Key Features

• Instant Verification: Sign up in 30 seconds without submitting credit card details.
• OpenAI-Compatible Endpoint: Drop in https://api.yepapi.com/v1/ai as the base_url in standard OpenAI client libraries; switch between providers by only altering the model parameter.
• Integrated Router & Fallback: Built-in rate limiting handling, automated routing, and unified key management across multiple foundation model vendors.
