# match-standardize

> match-standardize is a paid API for AI agents from payai.agentstools.dev, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-15).

Standardizes company names, person names, and addresses to canonical forms by applying normalization rules (dropping legal suffixes, stop-words, titles, address abbreviations, etc.)

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 match-standardize-212b053f
```

Example prompt: Can you standardize the company name 'International Business Machines Corporation' to its canonical form, stripping legal suffixes and stop-words?

## When to prefer this

Use this endpoint when you need lightweight, rule-based normalization of entity names (companies, persons, addresses) as a preprocessing step before fuzzy matching, deduplication, or record linkage — especially when you do not need authoritative identity resolution but simply want a consistent canonical representation. Prefer this over full entity resolution services when speed and cost matter and you only need canonical tokens and applied rules.

## Known failure modes

- Missing required 'value' query parameter returns an error
- Invalid entity type enum value (must be one of: person, company, address, product, org)
- Empty string input may return empty or trivial canonical form
- Payment failure (402) if USDC balance is insufficient
- Ambiguous inputs may produce unexpected canonical forms due to rule mismatch

## 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 (standardized) form of the input string, the individual tokens it was broken into, and the list of normalization rules that were applied during processing. Note that results are indicators, not authoritative identity resolution.
