# Puzzle API reference

> Host: `https://api.puzzle.team`  Auth: `Authorization: Bearer puz_live_…`

## Authentication

All v1 endpoints (except `GET /v1/models`) require an API key:

```
Authorization: Bearer puz_live_<32-hex>
```

Keys are created in the console at https://puzzle-cloud.com/dashboard, shown once, stored as SHA-256. If lost, revoke and create a new one.

## Models

**Live** (accepted by API):

- `nano-banana-v2`
- `nano-banana-pro`

**Coming soon** (return HTTP 422 `model_unavailable` until live):

- `omni`
- `veo`
- `gemini`

## Error codes

| HTTP | code | When |
|---|---|---|
| 400 | `invalid_json` | Body is not JSON |
| 400 | `invalid_request` | Missing model, prompt, or url |
| 401 | `unauthorized` | Missing or unknown API key |
| 402 | `insufficient_funds` | Balance is $0.00 — fund and retry |
| 404 | `job_not_found` | No accepted job with that id |
| 405 | `method_not_allowed` | Wrong HTTP method |
| 422 | `model_unavailable` | Omni / Veo / Gemini — not served yet |
| 429 | `rate_limited` | Account RPM exceeded |
| 500 | `internal_error` | Unexpected server failure |

### 402 `insufficient_funds`

Your key is valid but confirmed credit is $0.00. Fund your balance in the console (USDC/USDT on Ethereum, Tron, or BNB), wait for confirmation, then retry. 402 is expected — not a down endpoint.

---

## Funding

Crypto is self-serve in the console: USDC or USDT on Ethereum, Tron, or BNB. Log the tx hash after sending; balance is updated when Puzzle confirms the received amount.

---

## Webhooks

Pass `callback_url` (HTTPS) in the request body. When the job is accepted (`queued`), Puzzle POSTs JSON to that URL with header `X-Puzzle-Signature: sha256=<hex>` using your workspace signing secret.

## FAQ

**How do I get started?**  
Sign up, create a key, POST /v1 with a Bearer token. Keep your prompts — pointing an official Google SDK at our host will not work.

**What does 402 mean?**  
The key is valid and confirmed credit is $0.00. Fund, wait for confirmation, then retry. 402 is expected — not a down endpoint.

**Are my prompts used for training?**  
No. Puzzle does not use your prompts or outputs to train Google models or ours.

**Can I see an API key again?**  
No. Puzzle stores a SHA-256 hash. Copy the key when it is created. If you lose it, revoke it and make a new one.

**Do you guarantee uptime?**  
Only in a signed contract. Per-account rate limits exist and are unpublished. Telegram https://t.me/PUZZLE_Support_AI if you need either.

**Which models are available?**  
Nano Banana 2 and Nano Banana Pro are live. Omni, Veo, and Gemini return 422 until they ship.
