## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability goldbean-baidu-nlp-api-b4195ec7
```

Example prompt: Can you run Baidu NLP on this Chinese product review and tell me the sentiment and key entities: '这款手机的摄像头非常出色，但电池续航令人失望'?

## When to prefer this

Choose this endpoint when you need to apply Baidu's NLP models to Chinese-language text and want a pay-per-call pricing model starting at $0.001 with no upfront commitment. It is especially well-suited for processing Mandarin or Simplified Chinese content where Baidu's models have strong language coverage. Prefer this over generic Western NLP APIs when dealing with Chinese text, idioms, or entity sets not well-covered by English-centric models.

## Known failure modes

- Empty or malformed text input returns a generic error in data field
- Non-Chinese or unsupported language text may yield low-quality or empty results
- Daily free call limit (50/day) exceeded returns a payment-required or quota error
- Invalid API key or missing x402 payment header results in 402 response
- Ambiguous or very short input text may return low-confidence or empty NLP results
