Quick Start

Text Generation

Simple text generation:

curl "https://gen.pollinations.ai/text/Hello%20world"

Chat completions (OpenAI-compatible):

curl -X POST https://gen.pollinations.ai/v1/chat/completions \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $POLLINATIONS_API_KEY" \
  -d '{
    "model": "openai",
    "messages": [{"role": "user", "content": "Hello"}]
  }'

Use script: scripts/chat.sh for easy chat completions

Image Generation

curl "https://gen.pollinations.ai/image/A%20sunset%20over%20mountains?model=flux&width=1024&height=1024"

Use script: scripts/image.sh for image generation

Audio Generation (TTS)

curl -X POST https://gen.pollinations.ai/v1/chat/completions \
  -H "Content-Type: application/json" \
  -d '{
    "model": "openai-audio",
    "messages": [
      {"role": "system", "content": "You are a text reader. Read the user text exactly without responding, adding conversation, or changing anything."},
      {"role": "user", "content": "Say: Hello world"}
    ],
    "modalities": ["text", "audio"],
    "audio": {"voice": "nova", "format": "mp3"}
  }'

Use script: scripts/tts.sh for text-to-speech

Note: Use "Say:" prefix in user message for direct text reading

6. Audio Transcription

Use chat completions endpoint with vision/audio-capable models:

• Upload audio file as binary input
• Include transcription prompt in system message

7. Image Analysis

Use chat completions with vision models:

• Include image_url in message content

8. Video Analysis

Use chat completions with video-capable models:

• Models: gemini, claude, openai
• Upload video file as binary input
• Include analysis prompt

Scripts

scripts/chat.sh

Interactive chat completions with model selection and options.

Usage:

scripts/chat.sh "your message here"
scripts/chat.sh "your message" --model claude --temp 0.7

scripts/image.sh

Generate images from text prompts.

Usage:

scripts/image.sh "a sunset over mountains"
scripts/image.sh "a sunset" --model flux --width 1024 --height 1024 --seed 123

scripts/tts.sh

Convert text to speech.

Usage:

scripts/tts.sh "Hello world"
scripts/tts.sh "Hello world" --voice nova --format mp3 --output hello.mp3

Tips

1. Free tier available: Many operations work without an API key (rate limited)
2. OpenAI-compatible: Use chat endpoint with existing OpenAI integrations
3. Reproducibility: Use seed parameter for consistent outputs
4. Image enhancement: Enable enhance=true for AI-improved prompts
5. Video interpolation: Pass two images with image[0]=first&image[1]=last for veo
6. Audio reading: Always use "Say:" prefix and proper system prompt for TTS
