# Name & Address Standardization API

> Name & Address Standardization API is a paid API for AI agents from api.agentstools.dev, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-15).

Normalizes company names, person names, and addresses to canonical forms by applying rule-based pipelines that strip legal forms, titles, stop-words, and abbreviations

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 name-address-standardization-api-4364c446
```

Example prompt: Standardize the company name 'International Business Machines Corporation' as a company entity — strip the legal form and stop-words and give me back the canonical form and which rules were applied.

## When to prefer this

Use this endpoint when you need lightweight, rule-based normalization of entity names (companies, people, addresses) before fuzzy matching or deduplication — it is fast and cheap ($0.005/call) and returns both the canonical form and the rules applied, making it transparent. Prefer this over full entity resolution services when you need explainable, deterministic cleaning rather than probabilistic identity matching.

## Known failure modes

- Missing required 'value' query parameter returns an error
- Invalid 'type' enum value (not one of person/company/address/product/org) may default to company or error
- Very short or empty strings may return minimal or unchanged output
- Non-English names or scripts may not have coverage for all normalization rules
- Payment failure (x402) if USDC balance is insufficient

## How this service works

Standardize a company name, person name or address to a canonical form. Canonicalises legal forms, drops business stop-words, strips person titles and suffixes and folds address abbreviations. Returns the canonical form, the tokens and the rules that were applied. Indicators, not authoritative identity resolution.

## Output

Returns the canonical normalized form of the input string, a list of tokens the name was broken into, and the specific normalization rules that were applied (e.g. legal-form removal, title stripping, abbreviation folding). These are indicators for matching purposes, not authoritative identity resolution.
