## 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 omniapi-ai-classify-aab88764 -d '<json body>'
```

Example prompt: Classify this text using OmniAPI's AI classify endpoint and tell me what category it falls into: 'The battery drains within 2 hours of normal use and the screen flickered twice.'

## When to prefer this

Choose this endpoint when you need a quick, pay-per-call AI text classification without managing your own ML infrastructure. It is well-suited for agents that handle sporadic classification tasks across diverse domains (content moderation, intent detection, ticket routing) and want to pay micro-amounts in USDC rather than maintain a subscription. Prefer alternatives if you need fine-tuned domain-specific models, guaranteed SLAs, or bulk batch processing at lower per-call cost.

## Known failure modes

- Missing required 'query' field returns a 400 validation error
- Malformed JSON body results in a parsing error response
- Payment failure via x402 (insufficient USDC balance or unsupported facilitator) blocks the request
- Overly long input text may be truncated or rejected depending on model limits
- Ambiguous or empty query string may return low-confidence or null classification

## How this service works

444 endpoints across 9+ chains. Crypto, AI, Social, Finance, Weather, Tools. Pay per call in USDC via x402 with 4 facilitators: Dexter, Meridian, FluxA, GoPlausible.

## Output

Returns a structured JSON object containing the AI-generated classification result for the submitted query or input text, typically including a category label and potentially a confidence score or additional metadata fields.
