AIML API is a multi-model AI gateway that spans 8 modalities, from text and chat to image, video, voice, and 3D generation, all reachable through one OpenAI-compatible endpoint. Its core differentiator is breadth: a single key connects to models from OpenAI, Anthropic, Google, and Meta instead of one vendor at a time.
About AIML API
AIML API is a multi-model AI gateway founded in 2024 and headquartered in Estonia, providing developers access to AI models through a single OpenAI-compatible REST endpoint. The platform aggregates models from OpenAI, Anthropic, Google, Meta, DeepSeek, Alibaba, and dozens more, eliminating the need to manage separate API keys, billing accounts, and SDK configurations for each provider.
The technical foundation is a transparent proxy layer: developers change only their base URL and swap in an AIML API key, and their existing OpenAI SDK code works unchanged. Supported modalities include text and chat, image generation, video generation, text-to-speech, music generation, OCR, embeddings, and 3D generation, each routed to a different vendor backend behind the same key.
Pricing is pay-as-you-go with a prepaid credit and no recurring subscription fee — and no free plan: the vendor's own help center states plainly, "we don't offer a free plan, pricing is usage-based, so you only pay for what you use." The prepaid top-up ranges from $20 to $20,000, auto-renews for the same amount when the balance runs out (opt-out available), and unused funds do not expire; top-ups are non-refundable. The platform claims up to 80% cost savings compared to purchasing models directly from source providers.
Developers can access AIML API via official Python and Node.js SDKs, both Apache 2.0 licensed, and the platform integrates with LangChain, LiteLLM, Langflow, n8n, and Make.com. A hosted MCP (Model Context Protocol) connector also lets Claude, Cursor, Claude Code, and other MCP-compatible agents reach the full model catalog through a single sign-in instead of a REST integration. Documentation is at docs.aimlapi.com. Enterprise plans add dedicated servers, custom AI models, unlimited RPM and TPM, extended data storage, early access to model updates, staff onboarding, and a dedicated Slack channel — pricing is quote-only. GitHub repositories at github.com/aimlapi include SDKs, LangChain integration packages, and example agent frameworks under MIT and Apache licenses.

Pricing
" Pay-as-you-go requires a prepaid top-up between $20 and $20,000; the balance auto-renews for the same amount when it runs out (can be disabled), funds don't expire, and top-ups are non-refundable. 00 per 1M input tokens (Claude Opus 5 at $5/M input, $25/M output). 13 per image.
25 per second. 02 per 1K characters. Enterprise: custom pricing with dedicated servers, custom AI models, unlimited RPM/TPM, and extended data storage.

Key Features
- 400+ Model Gateway: One API key covers hundreds of models across text, image generation, video generation, audio, and music from a single endpoint.
- OpenAI-Compatible Drop-In: Change only the base URL to api.aimlapi.com/v1 and existing OpenAI SDK code reaches Claude, Gemini, Llama, and hundreds of other models with no further code changes required.
- Pay-As-You-Go Billing: No monthly subscription: pay only for usage from a small prepaid credit balance, with per-model rates that undercut buying access directly from each provider.
- Multimodal Coverage: Beyond text, the gateway reaches 8 additional modalities including OCR, 3D generation via TripoSR, embeddings, and speech-to-text through the same API key.
- SDK and Framework Integrations: MIT and Apache-licensed client libraries drop into LangChain, LiteLLM, Langflow, n8n, and Make.com pipelines, so existing automation workflows can add AIML API without a rewrite.
Pros
- A single prepaid credit activates access to models from OpenAI, Anthropic, Google, Meta, and DeepSeek, covering providers that would otherwise require a dozen separate accounts and billing relationships to access directly.
- OpenAI SDK compatibility means a single base URL change gives existing codebases access to Claude, Gemini, and dozens of non-OpenAI models, cutting migration time from days to minutes.
- Pay-as-you-go pricing with no monthly minimums suits variable or low-volume workloads where a fixed monthly subscription to each model provider would otherwise be wasteful.
Cons
- First-token latency of 0.84-0.90 seconds is roughly twice as slow as OpenRouter at 0.40-0.43 seconds, ruling AIML API out for real-time chat, voice, or any application where sub-500ms response is required.
- Founded in 2024 with 10 employees and no publicly disclosed funding, creating reliability and longevity risk for teams building production-critical infrastructure on the platform.
- User reports on public forums describe unauthorized charges and difficulty obtaining refunds, indicating billing dispute resolution needs significant improvement before the platform is suitable for production spend.
- There is no free plan or trial — AIML API's own help center says plainly "we don't offer a free plan" — so evaluating the gateway against a real workload means committing a minimum $20 prepaid top-up before the first API call.
Data Handling
- Training-data policy
- Neither the Privacy Policy nor the Terms of Service states whether prompts or API inputs are used to train models. Personal and transaction data is retained only "as long as is necessary," with no fixed retention period given; payment details are processed by Stripe and not stored by AIML API.
- Compliance
- None published — the Privacy Policy and Terms of Service name no SOC 2 · ISO 27001 · or HIPAA certification
Frequently Asked Questions
How much do you pay for AIML API?
AIML API charges no monthly subscription. You fund a prepaid balance up front, then pay per token or per generation as you use each model; text rates run as high as $39.00 per million input tokens for the priciest frontier model, versus a fraction of a cent for smaller ones. Image, video, and speech generation are billed per output instead of per token, and enterprise plans add custom volume pricing with dedicated servers.
Can you use AIML API without paying?
No. AIML API's own help center is direct: "we don't offer a free plan, pricing is usage-based, so you only pay for what you use." Every model is billed from a prepaid balance that starts at a $20 minimum top-up; a bonus-credit promotion exists on the platform but is currently marked "temporarily unavailable."
Which tools compete with AIML API in 2026?
OpenRouter is the closest single-endpoint rival, with quicker first-token response times but a narrower catalog focused mostly on text models. CometAPI runs a similar gateway at a flat discount off provider rates, though it stops short of AIML API's video, voice, and 3D-generation routes. Raw inference speed is Groq's specialty, and it beats AIML API there if speed matters more than model breadth.
Is AIML API better than OpenRouter?
OpenRouter typically answers in well under half a second, noticeably faster than AIML API's first-token response time, which makes it the better fit for live chat or voice products. AIML API pulls ahead on breadth, reaching video, voice, and 3D-generation endpoints that OpenRouter does not route directly, which suits batch or evaluation workloads better than real-time ones.
How do you set up AIML API?
Create an account, load a prepaid credit balance (minimum $20 — there is no free plan), then point your existing OpenAI SDK at AIML API's base URL and drop in your new API key. Existing OpenAI-format code keeps working unchanged, and every model you call afterward is billed from that same prepaid balance.
Top Alternatives
- OpenRouter: OpenRouter answers faster on that first token, which matters most for live chat; AIML API trades a bit of that speed for routes into video, voice, and 3D generation OpenRouter doesn't carry.
- CometAPI: CometAPI's flat discount undercuts AIML API on pure provider-rate pricing. What it doesn't reach is AIML API's video, voice, and 3D-generation endpoints, so the choice comes down to price versus modality breadth.
- Groq: Groq wins outright on raw inference speed for the models it supports. AIML API's advantage is coverage: one key that also reaches image, video, and voice generation, which Groq's catalog doesn't cover.
