The LLM API that gives you 130+ models through one endpoint

YepAPI's LLM API is a unified AI gateway and AI models API that gives you access to 130+ AI models through a single OpenAI compatible API endpoint. Use the GPT-4o API, DeepSeek API, Claude API, Gemini API, Llama API, and Qwen API — all through one LLM API endpoint. Send the same request format you use with OpenAI and switch models by changing one parameter.

Looking for a free AI API to start with? Get $5 free credit on signup — no credit card — then pay as you go, per token, with no subscriptions. The DeepSeek API starts at $0.20/M input tokens. The GPT-4o API costs $3.50/M input. Claude API pricing starts at $1.12/M for Haiku. No monthly minimums makes this the LLM API developers reach for when they want pay-as-you-go pricing with broad model coverage.

YepAPI works as an AI gateway and LLM router — one key, one bill, one dashboard. Building an AI agent, chatbot, or content tool? This LLM API works with any framework — LangChain, LlamaIndex, Vercel AI SDK, or raw HTTP calls. Plus, your same API key covers web scraping, SEO data, SERP results, and YouTube APIs. Compare OpenRouter pricing to YepAPI — same models, better value.

OpenRouter alternative — better pricing, more APIs

Compare OpenRouter pricing to YepAPI: same LLM API access, but YepAPI bundles web scraping, SEO, SERP, and YouTube APIs under one key. The cheapest AI API with no monthly minimums.

AI API — Frequently asked questions

An AI API gives you programmatic access to large language models (LLMs) like GPT-5.4, Claude, Gemini, and DeepSeek. You send a prompt via HTTP request and get back generated text, code, or structured data. YepAPI's AI API is a unified endpoint — one API key accesses 130+ models from OpenAI, Anthropic, Google, Meta, and more.

YepAPI gives you $5 free credit on signup — no credit card required. That's enough for thousands of API calls on cheaper models like DeepSeek, Llama, or Qwen. There's no free tier with hard limits — you get real credits to use on any model, then pay as you go.

Sign up for YepAPI and your single API key works as your Claude API key — the same key also accesses GPT-5.4, Gemini, DeepSeek, and 60+ other models. No Anthropic enterprise contract or separate Claude API key required. You get $5 free credit on signup (no credit card), then pay per token: Claude Haiku 4.5 from $1.12/M input, Claude Sonnet 4.6 at $4.20/M input. Use it with the OpenAI SDK by changing the base URL — your Claude API key works through the same OpenAI-compatible endpoint.

OpenAI API pricing through YepAPI is simple per-token billing. GPT-4o costs $3.50/M input and $14/M output; GPT-4o mini costs $0.21/M input and $0.84/M output; GPT-5.4 and GPT-5.5 are available per token. There are no monthly minimums or subscriptions — your $5 free credit covers thousands of OpenAI API calls, then you pay per token. The same key also accesses Claude, Gemini, and DeepSeek through one OpenAI-compatible endpoint.

An LLM gateway is a unified API layer that sits between your app and multiple AI model providers. Instead of integrating with OpenAI, Anthropic, Google, and Meta separately, you connect to one gateway. YepAPI acts as an LLM gateway and router — one endpoint, one key, one billing dashboard. Switch between models by changing a single parameter.

Through YepAPI, DeepSeek V3.2 costs $0.36/M input tokens and $0.53/M output tokens. DeepSeek R1 (reasoning model) costs $0.77/M input and $3.07/M output. No monthly minimums — pay per token, starting from your $5 free credit.

An OpenAI-compatible API uses the same request and response format as OpenAI's API. Any code written for the OpenAI SDK works with YepAPI — just change the base URL and API key. This means you can access Claude, Gemini, DeepSeek, and Llama models using the same OpenAI client libraries you already use.

YepAPI serves a similar role to OpenRouter — both are LLM gateways that give you access to multiple AI models through one API. The differences: YepAPI bundles web scraping, SEO, SERP, and YouTube APIs under the same key, uses straightforward pay-per-token pricing, and gives you $5 free credit to start. If you want an OpenRouter alternative with broader API coverage, YepAPI is it.

Claude API pricing through YepAPI is per-token. Claude Sonnet 4.6 costs $4.20/M input and $21/M output. Claude Haiku 4.5 costs $1.12/M input and $5.60/M output. Claude Opus 4.8 costs $7/M input and $35/M output. No monthly minimums — pay only for the tokens you use. Access the Claude API without an Anthropic enterprise contract.

The GPT-4o API through YepAPI costs $3.50/M input tokens and $14/M output tokens. GPT-4o mini costs $0.21/M input and $0.84/M output. No monthly subscriptions or minimums. Your $5 free credit covers thousands of GPT-4o API calls. Switch between GPT-4o and any other model by changing one parameter.

YepAPI is an affordable LLM API for accessing multiple AI models. DeepSeek models start at $0.20/M tokens. Llama models start at $0.21/M tokens. Qwen models start at $0.07/M tokens. No monthly minimums, and $5 free credit on signup. Compare that to juggling OpenRouter or going direct to each provider — YepAPI gives you the broadest model coverage under one key.

OpenRouter pricing and YepAPI pricing are both per-token with no monthly minimums. The key differences: YepAPI bundles web scraping, SEO, SERP, and YouTube APIs under the same key — OpenRouter is LLM-only. YepAPI gives you $5 free credit on signup. Both offer the same models (GPT-4o API, DeepSeek API, Claude API, Gemini), but YepAPI is a more complete AI gateway for developers building data-driven apps.

DeepSeek API pricing through YepAPI: DeepSeek V3.2 costs $0.14/M input and $0.28/M output tokens. DeepSeek R1 (reasoning model) costs $0.55/M input and $2.19/M output. The DeepSeek API is one of the cheapest LLM APIs available — $5 free credit covers tens of thousands of calls. No monthly minimums, no subscriptions.
