pollinations-api — Pollinations REST API

Direct REST access to https://gen.pollinations.ai without installing the CLI. The image URL works keyless; authenticated calls use POLLINATIONS_API_KEY. If no key is available, the user can approve a device sign-in in their own browser. With no user to approve, an agent can buy a prepaid key over x402 (below).

Use the polli CLI skill when the CLI is already installed. Use this skill when it is not (sandboxes, Codex cloud, Cursor chat, fresh containers) or when you only need one quick call.

Auth

Keyless (no header): GET /image/{prompt}.
Authenticated: header Authorization: Bearer $POLLINATIONS_API_KEY (an existing key, or a user-approved device sign-in below).
Same key permissions, billing and caching as the CLI path.

Get a key without copying one into the agent

If POLLINATIONS_API_KEY is already set, skip this. Otherwise ask the user to approve sign-in, then use the OAuth 2.0 Device Authorization Grant (RFC 8628). The user opens the printed URL on their own device; the agent polls at the server-provided interval. No credential goes into a chat, command argument, URL, public repository, or log. This uses Python's standard library only:

python3 - <<'PYDEVICE'
import json, os, time, urllib.error, urllib.parse, urllib.request
from pathlib import Path

path = Path.home() / '.config/pollinations/agent-key'
if path.exists():
    print('Existing private key file:', path)
    raise SystemExit(0)

def post(route, fields):
    request = urllib.request.Request(
        'https://enter.pollinations.ai' + route,
        data=urllib.parse.urlencode(fields).encode(),
        headers={'Content-Type': 'application/x-www-form-urlencoded'},
    )
    try:
        with urllib.request.urlopen(request, timeout=15) as response:
            return json.load(response)
    except urllib.error.HTTPError as error:
        return json.load(error)  # Pending approval is an OAuth 400 response.

code = post('/api/device/code', {})
print('Ask the user to approve:', code['verification_uri_complete'], flush=True)
interval = code['interval']
deadline = time.monotonic() + code['expires_in']
while time.monotonic() < deadline:
    time.sleep(interval)
    token = post('/api/oauth/token', {
        'grant_type': 'urn:ietf:params:oauth:grant-type:device_code',
        'device_code': code['device_code'],
    })
    if token.get('error') in ('authorization_pending', 'slow_down'):
        if token['error'] == 'slow_down':
            interval += 5
        continue
    if token.get('error'):
        raise SystemExit('Authorization failed: ' + token['error'])
    path.parent.mkdir(mode=0o700, parents=True, exist_ok=True)
    fd = os.open(path, os.O_WRONLY | os.O_CREAT | os.O_EXCL, 0o600)
    with os.fdopen(fd, 'w') as file:
        file.write(token['access_token'])
    print('Saved to private file:', path)  # Never print the token.
    break
else:
    raise SystemExit('Approval timed out; request a new code.')
PYDEVICE
export POLLINATIONS_API_KEY="$(cat ~/.config/pollinations/agent-key)"

Do not run this under shell tracing (set -x). Keep that file out of projects; its permissions are 0600. The user can revoke the issued key on the Pollinations keys page. For all grant options and the browser consent details, see Bring Your Own Pollen.

No one to approve: buy a prepaid key with x402

An agent with USDC on Base can buy a key without a Pollinations account. Spend only with the user's permission.

GET https://enter.pollinations.ai/api/x402/keys/0.50 asks for a $0.50 key (any amount from $0.01 to $10,000). It returns 402 with payment terms in the PAYMENT-REQUIRED header.
An x402 client signs those terms and retries with PAYMENT-SIGNATURE. The response holds the new secret key and its pollen budget.

Each payment creates a new key; store it like the device sign-in key above.

First call (keyless image, no code)

https://gen.pollinations.ai/image/a%20cat%20in%20space?model=flux

Open the URL or curl -o out.png "<url>". If it returns an image, discovery works.

Text (OpenAI-compatible)

from openai import OpenAI
client = OpenAI(base_url="https://gen.pollinations.ai/v1", api_key="YOUR_API_KEY")
response = client.chat.completions.create(model="openai/gpt-5.4-nano", messages=[{"role": "user", "content": "Hello!"}])
print(response.choices[0].message.content)

curl https://gen.pollinations.ai/v1/chat/completions \
  -H "Authorization: Bearer $POLLINATIONS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model":"openai/gpt-5.4-nano","messages":[{"role":"user","content":"Hello!"}]}'

Audio (one-shot TTS)

curl "https://gen.pollinations.ai/audio/Hello%20world?voice=nova" \
  -H "Authorization: Bearer $POLLINATIONS_API_KEY" -o speech.mp3

Model IDs

IDs use publisher/model names; existing aliases stay valid — match catalog entries against both canonical ID and aliases.
Catalog metadata uses publisher (for example, OpenAI), not brand.
Current IDs: https://gen.pollinations.ai/models.
