## 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 entity-name-standardization-endpoint-c7fb6c53
```

Example prompt: Can you standardize the company name 'Intl Business Machines Corp.' for me — use the company normalization pipeline so it comes back in a clean, canonical format?

## When to prefer this

Choose this endpoint when you need to normalize or canonicalize entity name strings — especially company names, person names, addresses, products, or org names — prior to matching, deduplication, OFAC screening, or database ingestion. It is particularly useful when entity type context is known, enabling type-specific normalization pipelines rather than generic text cleaning.

## Known failure modes

- Missing required 'value' query parameter returns an error
- Invalid or unsupported entity type enum value causes pipeline selection failure
- Empty string input may return an empty or unchanged result
- Network timeout or service unavailability returns a non-200 response
- Payment failure via x402 protocol blocks request before processing

## How this service works

X402 micropayments server — AI agents pay USDC for OFAC screening, rates, and billing verification.

## Output

Returns a JSON object with a 'success' boolean and a 'result' object containing the standardized/normalized form of the input entity string, processed through the selected type-specific pipeline.
