Pollinations is a multi-modal AI generation API — OpenAI-compatible, covering text, image, video, audio, and embeddings. One base URL, many modalities.

---

Quick Start (No Code)

# Image via URL — zero code, zero auth
https://gen.pollinations.ai/image/a%20cat%20in%20space?model=flux

# Text via URL
https://gen.pollinations.ai/text/explain%20quantum%20tunneling

# Audio via URL (auth required)
curl "https://gen.pollinations.ai/audio/Hello%20world?voice=nova" \
  -H "Authorization: Bearer YOUR_API_KEY" -o speech.mp3

---

Authentication

Get a key at enter.pollinations.ai.

Key type	Prefix	Use case	Rate limits
Secret	sk_	Server-side / backend	None
Publishable	pk_	Client-side / frontend (beta)	1 pollen/IP/hour

Two auth methods:

Authorization: Bearer YOUR_API_KEY    # header
?key=YOUR_API_KEY                     # query param

⚠️ Never expose sk_ keys in frontend/client-side code. Use pk_ there.

const client = new OpenAI({
  baseURL: "https://gen.pollinations.ai",
  apiKey: process.env.POLLINATIONS_API_KEY,
});

const response = await client.chat.completions.create({
  model: "openai",
  messages: [{ role: "user", content: "Hello!" }],
});
console.log(response.choices[0].message.content);

Safety Filtering

Optional. Apply via query param, body field, or header:

?safe=privacy          # redact PII
?safe=secrets          # redact keys/passwords
?safe=sexual           # block sexual content (returns 400)
?safe=violence         # block violent content
?safe=shield           # block all harmful content
?safe=true             # = privacy,secrets
?safe=nsfw             # = sexual,violence

# Via header
-H "Pollinations-Safe: privacy"

Blocked → 400 with error.type: "safety_error".
