AI Models API

Text and image generation over a single HTTP endpoint. No SDK, no keys to pass — just hit the URLs below.

\n\n

\n This API gives you two things: a chat endpoint that returns text from a language model,\n and an image endpoint that turns a text prompt into an image and hands you back a hosted URL.\n Everything speaks JSON. You can call it from a browser, curl, a phone app, or any backend.\n

\n\n

\n There's no auth on these routes — the server holds the model token internally, so you only\n deal with prompts and responses. If you're building a public app, put your own rate limiting in front of it.\n

\n\n

Base URL

All routes are relative to the deployment origin:

\n\n

Quick start

The fastest way to see it work — open this in your browser:

\n\n \n

Chat

Send a prompt, get text back. There are two ways to call it.

\n\n

\n GET\n /v1/chat?prompt=...\n

Good for quick tests and simple one-liners. Put your question in the prompt query parameter.

curl \"$BASE/v1/chat?prompt=What%20is%20the%20capital%20of%20France%3F\"

\n\n

\n POST\n /v1/chat\n

Use this when you want a system prompt, a full conversation, or generation settings. Send JSON.

\n\n

Body fields

\n \n \n \n \n \n \n \n \n

Field	Type	Notes
`prompt`	string	Shortcut for a single user message. Use this or `messages`.
`messages`	array	Full chat history. Each item is `{ \"role\": \"system\" \| \"user\" \| \"assistant\", \"content\": \"...\" }`.
`model`	string	optional · defaults to `openai/gpt-oss-120b:groq`
`temperature`	number	optional · 0–2, higher is more random
`max_tokens`	number	optional · cap on response length
`top_p`	number	optional · nucleus sampling

\n\n

Example — single prompt

curl -X POST \"$BASE/v1/chat\" \\\n  -H \"Content-Type: application/json\" \\\n  -d '{\n    \"prompt\": \"Give me three names for a coffee shop.\"\n  }'

\n\n

Example — full conversation

curl -X POST \"$BASE/v1/chat\" \\\n  -H \"Content-Type: application/json\" \\\n  -d '{\n    \"model\": \"openai/gpt-oss-120b:groq\",\n    \"temperature\": 0.7,\n    \"messages\": [\n      { \"role\": \"system\", \"content\": \"You answer in one short sentence.\" },\n      { \"role\": \"user\", \"content\": \"Why is the sky blue?\" }\n    ]\n  }'

\n\n

Response

{\n  \"model\": \"openai/gpt-oss-120b\",\n  \"reply\": \"Sunlight scatters off air molecules, and blue light scatters most.\",\n  \"usage\": {\n    \"prompt_tokens\": 24,\n    \"completion_tokens\": 14,\n    \"total_tokens\": 38\n  }\n}

\n\n \n

Image

\n Describe an image, get back a hosted URL you can drop into an <img> tag.\n The server generates the image, uploads it for you, and returns the link.\n

\n\n

\n GET\n /v1/image?prompt=...\n

\n POST\n /v1/image\n

\n\n

Body / query fields

\n \n \n \n \n \n \n

Field	Type	Notes
`prompt`	string	What you want to see. Required.
`model`	string	optional · defaults to `Tongyi-MAI/Z-Image-Turbo`
`negative_prompt`	string	optional · things to avoid in the image
`raw`	boolean	optional · if true, returns the raw image bytes instead of a JSON URL

\n\n

Example

curl -X POST \"$BASE/v1/image\" \\\n  -H \"Content-Type: application/json\" \\\n  -d '{\n    \"prompt\": \"An astronaut riding a horse, cinematic lighting\"\n  }'

\n\n

Response

{\n  \"prompt\": \"An astronaut riding a horse, cinematic lighting\",\n  \"model\": \"Tongyi-MAI/Z-Image-Turbo\",\n  \"url\": \"https://jerrycans-file.hf.space/files/gen-1717000000000.png\",\n  \"content_type\": \"image/png\"\n}

\n\n

Want the image bytes directly (e.g. to pipe into a file)? Add ?raw=true:

curl \"$BASE/v1/image?prompt=a%20red%20bicycle&raw=true\" --output bike.png

\n\n \n

Calling it from code

\n\n

JavaScript

const base = \"$BASE\";\n\n// chat\nconst chat = await fetch(`${base}/v1/chat`, {\n  method: \"POST\",\n  headers: { \"Content-Type\": \"application/json\" },\n  body: JSON.stringify({ prompt: \"Write a haiku about the sea.\" }),\n}).then(r => r.json());\nconsole.log(chat.reply);\n\n// image\nconst img = await fetch(`${base}/v1/image`, {\n  method: \"POST\",\n  headers: { \"Content-Type\": \"application/json\" },\n  body: JSON.stringify({ prompt: \"A lighthouse at dusk\" }),\n}).then(r => r.json());\nconsole.log(img.url);

\n\n

Python

import requests\n\nbase = \"$BASE\"\n\nchat = requests.post(f\"{base}/v1/chat\", json={\n    \"prompt\": \"Explain gravity to a five year old.\"\n}).json()\nprint(chat[\"reply\"])\n\nimg = requests.post(f\"{base}/v1/image\", json={\n    \"prompt\": \"A fox in a snowy forest\"\n}).json()\nprint(img[\"url\"])

\n\n \n

Errors

Failures come back as JSON with the matching HTTP status:

{\n  \"error\": \"Provide a 'prompt' describing the image\",\n  \"detail\": null\n}

\n \n \n \n \n \n \n \n

Status	Meaning
`400`	Bad input — missing prompt, malformed JSON, etc.
`404`	Route doesn't exist.
`405`	Wrong HTTP method for that route.
`429`	Rate limited upstream — slow down and retry.
`5xx`	Model or upload host had a problem. The `detail` field usually says what.

\n\n

Endpoints at a glance

\n \n \n \n \n \n \n

Route	Method	Does
`/`	GET	This page.
`/health`	GET	Liveness check.
`/v1/chat`	GET / POST	Text generation.
`/v1/image`	GET / POST	Image generation → hosted URL.
