## 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 mart402-com-company-enrichment-7813eb35 -d '<json body>'
```

Example prompt: Can you pull a verified company profile for Stripe — including their LEI number if they have one — and show me the evidence sources and confidence scores for each field?

## When to prefer this

Prefer this endpoint when you need per-field evidence and confidence scores rather than bulk firmographic data, when GLEIF LEI matching is required for compliance or KYB workflows, or when honest nulls are preferable to hallucinated or low-quality data. It is especially suited to AI agent pipelines that need to cite primary sources for each data point. Choose alternatives if you need high-volume batch enrichment at lower cost or if you only need unverified firmographic data.

## Known failure modes

- Company not found in any primary source — fields returned as nulls with low confidence
- GLEIF LEI not matched — LEI field returned as null
- Ambiguous company name with multiple matches — may return best-guess or require domain disambiguation
- Network or upstream registry timeout — 5xx error returned
- Malformed input (no recognizable company name or domain) — 4xx validation error
- Payment not processed (x402 protocol failure) — request rejected before enrichment

## How this service works

Company enrichment: name, domain or URL to verified company profile from primary sources + GLEIF LEI registry. Per-field evidence and confidence, honest nulls. Flat 0.015/company.

## Output

A JSON company profile where each field (e.g. legal name, address, industry, founding date, website) includes an evidence URL pointing to a primary source and a calibrated confidence score. Fields that cannot be verified are returned as honest nulls rather than guesses. When a GLEIF LEI is matched, the LEI code and registry link are included.
