Model Catalog

Compose.Market provides unified access to AI models through a single API with x402-native payment. The curated catalog has 700+ models across multiple families and modalities.

Two catalogs

Catalog	Access
Curated	`GET /v1/models` — verified pricing, validated capabilities

Providers

Provider	Specialization
Alibaba	Text (Qwen), speech (CosyVoice), video (Wan), vision, embeddings
Roboflow	Object detection, segmentation, OCR, image embeddings
Cloudflare	Edge inference, LLMs, vision, speech via Workers AI
Gemini	Multimodal text, vision, realtime, TTS, video
Azure	Hosted OpenAI models with data residency
OpenAI	GPT, Sora, embeddings, realtime
Fireworks	Open-source LLMs and rerankers
Cartesia	Low-latency text-to-speech
ElevenLabs	Voice generation, music, realtime transcription
Deepgram	Speech recognition (Nova-3)
ASICloud	Specialized inference

Modalities

Text generation
Speech
Image generation
Video generation
Realtime
Embeddings

Specialized vision operations — detection, segmentation, OCR, keypoints, classification — are exposed through Roboflow models in the image/vision modality.

Model examples

Model	Provider	Modality
`gpt-5.5`	Azure / OpenAI	Text
`FLUX.2-pro`	Black Forest Labs	Image
`sora-2`	OpenAI	Video
`cosyvoice-v3-flash`	Alibaba	Speech
`gemini-3-flash-preview`	Gemini	Text, vision, realtime
`qwen3`	Alibaba	Text
`deepseek-v4-flash`	DeepSeek	Text
`text-embedding-3-large`	OpenAI	Embeddings

Quick example

curl https://api.compose.market/v1/chat/completions \
  -H "Authorization: Bearer compose-..." \
  -H "Content-Type: application/json" \
  -d '{
    "model": "gpt-5.5",
    "messages": [{"role": "user", "content": "Hello"}]
  }'

API compatibility

All models use OpenAI-compatible endpoints. The model string is the contract — Compose resolves the provider from the catalog row, not by inspecting the prompt. Duplicate upstream model IDs get explicit public aliases (e.g. gpt-5.5 → Azure, openai/gpt-5.5 → OpenAI).

Pricing

The API applies a 1% platform fee on top of the raw provider amount. OpenRouter charges 5.5%. Compose charges 1% — a 5.5x difference that is factual. Pricing is dynamic: each model’s price comes from the generated catalog, not a fixed table.

Inference — full API surface, native and external routes
SDK Inference — TypeScript API for model calls
Quickstart — list models, chat, and stream
Metering — how provider output becomes a bill
