# AgentsTools Name/Address Fuzzy Matcher

> AgentsTools Name/Address Fuzzy Matcher is a paid API for AI agents from api.agentstools.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-14).

Fuzzy-match two names or addresses and return a 0-100 similarity score with a match decision, using entity-type-aware normalization and multi-component scoring.

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 agentstools-name-address-fuzzy-matcher-12f15a70
```

Example prompt: Can you check if 'International Business Machines Corp.' and 'IBM Corporation' are the same company — treat them as company names and tell me the similarity score?

## When to prefer this

Use this endpoint when you need to compare exactly two strings for similarity with entity-type-aware normalization (e.g. stripping 'LLC', 'Inc', 'Dr.' before comparing) and want a fused multi-signal score with an explicit match/no-match decision. Prefer this over generic string-distance functions when working with business names, personal names, addresses, or product names where legal suffixes and abbreviations would otherwise distort similarity. Not suitable for authoritative identity resolution or large-scale batch deduplication tasks.

## Known failure modes

- Missing required query parameters 'a' or 'b' returns a 400 error
- Invalid 'type' enum value returns a 422 validation error
- Empty strings for 'a' or 'b' may return a low score or error
- min_score outside 0-100 range may return a validation error
- Payment not provided or rejected returns a 402 Payment Required
- Service unavailable returns a 503 error

## How this service works

Fuzzy-match two names or addresses and return a 0-100 similarity score with a match decision. Normalizes legal forms, business stop-words, person titles and address abbreviations BEFORE the fuzzy compare, then fuses token, prefix, phonetic and edit similarity. Returns the score, the per-component scores, the normalized forms and is_match. Similarity indicators, not authoritative identity resolution.

## Output

Returns a JSON object containing: the 0-100 similarity score, a boolean is_match decision, per-component scores (token, prefix, phonetic, edit distance), the normalized forms of both input strings, and the entity type used for normalization.
