## 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 agentbit-app-text-classifier-5e2fb1a3 -d '<json body>'
```

Example prompt: Classify this support message into one of these labels — billing, technical-issue, account-access, or general-inquiry — and give me a confidence score: 'I can't log into my account after resetting my password yesterday.'

## When to prefer this

Choose this endpoint when you need fast, cheap, high-volume text classification with custom label sets — especially for routing, tagging, moderation triage, or intent detection workflows. It supports both single-label and multi-label modes and accepts optional natural-language instructions to guide the classifier, making it more flexible than fixed-schema sentiment APIs. At $0.005 per call it is cost-effective for large-scale automated pipelines.

## Known failure modes

- Empty text field returns validation error
- More than 30 labels provided triggers a limit error
- Missing required fields (text or labels) returns 400 bad request
- Very ambiguous or very short text may yield low confidence scores across all labels
- Labels list with only one entry may produce degenerate results
- Payment failure or insufficient USDC balance returns 402 payment required

## How this service works

Classify text into your labels with confidence and per-label scores. Single- or multi-label. Cheap and high-volume: routing, tagging, moderation triage, intent.

## Output

Returns the predicted label or labels for the input text along with a confidence score for the top prediction and individual scores for each candidate label in the provided list. In multi-label mode, multiple labels may be returned when confidence warrants.
