# Entity Name Fuzzy Matcher

> Entity Name Fuzzy Matcher is a paid API for AI agents from x402helper.xyz, paid per call via x402, $0.013/call, status unknown (last checked 2026-11-07).

Compares two name strings and returns a fuzzy match score indicating how similar they are, with optional entity-type-specific normalization.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-fuzzy-matcher-c64cec15
```

Example prompt: Can you check if 'International Business Machines' and 'IBM Corp' are the same company — run a fuzzy name match between them using the company entity type?

## When to prefer this

Use this endpoint when you need to programmatically compare two name strings — especially for entity types like persons, companies, addresses, or organizations — and want a normalized similarity score with configurable match thresholds. Prefer it over generic string-distance libraries when entity-type-aware normalization (e.g. handling 'LLC', 'Inc', common abbreviations) is important for accuracy.

## Known failure modes

- Missing required 'a' or 'b' query parameters returns an error
- Invalid entity type enum value causes validation failure
- Non-string input for name fields may cause unexpected results
- Score threshold outside 0-100 range may be rejected
- Payment failure via x402 protocol blocks access to the endpoint

## How this service works

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

## Output

A JSON object with a 'success' boolean and a 'result' object containing the fuzzy match score and match determination between the two input name strings.
