## AI/ML API

AI/ML API is a developer-first aggregation layer for generative AI. Instead of signing up with each model vendor separately, you get a single universal endpoint plus an OpenAI-compatible SDK, so existing code that points at OPENAI_API_KEY, ANTHROPIC_API_KEY or GEMINI_API_KEY can be redirected to a single AIML_API_KEY and switch between models without rewriting integrations. The catalogue spans chat and reasoning models, code models, image and video generators, text-to-speech and music models, embeddings, OCR, moderation and image-to-3D pipelines.

Beyond raw models, the platform ships an MCP tool surface with 1,000+ connectors covering web search, YouTube transcripts, X/Twitter scraping, LinkedIn jobs, Reddit research and marketing/SEO data, which lets agent builders combine model reasoning with live external data. A routing layer called Jev Router automatically sends simple tasks to cheap, fast models and reserves frontier models for hard work, with the vendor claiming automatic cost reductions of up to 50%. Usage is metered per token, image, second of video or second of audio, with the company stating no markup over going direct to the provider.

The service targets startups and production engineering teams as well as enterprises. Self-serve accounts top up from a small minimum balance and pay for exactly what they consume, while larger organisations can request custom pricing, dedicated servers, private model deployments and higher rate limits with a dedicated account manager. Privacy documentation states that customer inputs are not used to train or fine-tune models.

**Pricing & Plans:** Pay-as-you-go with credits you can top up from around $20, billed per token, image, video second or audio second with a stated 0% markup over provider list prices. An enterprise tier with custom pricing, dedicated servers, private models and unlimited rate limits is available on request.

- **Unified multi-provider endpoint:** Call chat, code, image, video, audio, music, embedding, OCR and 3D models from 70+ providers through one API key and one SDK.
- **OpenAI-compatible integration:** Point existing OpenAI, Anthropic or Gemini SDK code at AI/ML API and swap models by changing the model string rather than the integration.
- **Jev Router cost optimisation:** An automatic router grades task difficulty and sends easy work to cheap models while escalating hard work to stronger ones.
- **1,000+ MCP agent tools:** Give agents live access to Google search, YouTube transcripts, X/Twitter, Reddit, LinkedIn jobs and SEO/marketing data sources.
- **Single consolidated bill:** Model calls and agent tools are metered from one balance with per-category usage receipts for tokens, images, video and audio.

**Strengths:** Very broad model catalogue behind one credential and one invoice; Drops into existing OpenAI-style code with minimal changes; MCP tool library adds research and data capabilities beyond raw models; Stated zero markup makes price comparison against direct providers straightforward

**Limitations:** You depend on a third party in the request path, so platform incidents affect all providers at once; Cost predictability requires active monitoring of per-token and per-second metering; Some cutting-edge model availability can lag the direct provider release

## Stable Diffusion API

Stable Diffusion API gives developers a single HTTP endpoint for the whole Stable Diffusion family and a long list of community checkpoints. Instead of provisioning GPUs, installing PyTorch, and keeping model weights in sync, you send a POST request with a prompt, model id and parameters, and receive generated images plus a track id you can poll or receive via webhook. The catalog the site advertises covers SD 1.5, SDXL, Stable Diffusion 3, FLUX.1 dev/Schnell, FLUX.2 dev, Qwen Image, Z-Image Turbo, video models such as Wan 2.2 and LTX Video, and dedicated families like Realistic Vision, Juggernaut XL, Pony Diffusion, DreamShaper and Illustrious XL.

Beyond plain text-to-image, the API exposes image-to-image, inpainting, upscaling, background removal, ControlNet conditioning, LoRA usage and Dreambooth-style model fine-tuning, so a single integration can cover asset generation, product mockups, advertising variants and interior or fashion visuals. Official code samples for cURL, Python and Node are published for each model page, which shortens the time from signup to a first working request.

The platform is now presented as part of ModelsLab: accounts, API keys and billing live in the ModelsLab dashboard, and the site states that API requests are processed at scale with a 99.99% uptime target. Pricing is transparent and outlined on the site, with plans starting at $21 per month and an unlimited open-source tier for high-volume workloads.

**Pricing & Plans:** Paid plans billed through ModelsLab: Basic $21/month (3,250 API calls, 5 parallel generations), Standard $47/month (10,000 calls, 10 parallel generations), and Open Source Unlimited $149/month or $1,500/year (unlimited generations on self-hosted open-source models, 15 parallel generations). Third-party and closed models are billed separately; Enterprise offers dedicated GPUs and custom SLAs. Creating an account is free, but API access requires a paid plan.

- **Unified REST endpoint:** One POST endpoint handles text-to-image, image-to-image and editing jobs across SD 1.5, SDXL, Flux, ControlNet and LoRA models, with cURL, Python and Node samples for each model.
- **Large community model catalog:** Thousands of community checkpoints and LoRAs, including anime, photorealistic and stylized families, are browsable with their parameters and sample code.
- **Async jobs and webhooks:** Requests return a job id or track id so long-running generations can be polled or pushed to your own webhook endpoint instead of blocking the client.
- **Fine-tuning and training:** Dreambooth-style endpoints let you train custom concepts and styles on your own images, then reuse the resulting model ids in generation calls.
- **Scaling controls and enterprise options:** Parallel generation limits grow by plan, and an enterprise tier provides dedicated GPUs with custom SLAs for high-volume production traffic.

**Strengths:** Single API surface for many base models and thousands of community checkpoints; No GPU provisioning, driver or model-weight maintenance on your side; Publishing-ready code samples for cURL, Python and Node per model; Transparent tiered pricing with an unlimited open-source plan and enterprise GPUs

**Limitations:** API access requires a paid subscription; the free account only unlocks the dashboard; Third-party and closed models are billed separately from the unlimited open-source plan; Call quotas are counted per request, so batch-heavy experiments can consume a plan quickly
