## 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 agent402-tools-entity-enrichment-c435224d -d '<json body>'
```

Example prompt: Pull a full identity dossier on Stripe — I need their Wikidata facts, LEI legal-entity record, SEC EDGAR filing, domain registration details, tech stack, and favicon. Their domain is stripe.com and ticker is not relevant here so just use the name and domain.

## When to prefer this

Use this endpoint when you need a comprehensive, multi-source company identity dossier in a single API call rather than querying Wikidata, GLEIF, SEC EDGAR, and WHOIS separately. Ideal for KYC/KYB pre-screening, vendor due diligence, competitive intelligence, or compliance workflows where legal identity, financial filing history, and web presence all need to be correlated. Prefer this over individual lookup endpoints when you have a company name and optionally a domain or ticker, and need the full picture without orchestrating multiple APIs.

## Known failure modes

- Company name too ambiguous to resolve a unique Wikidata entity — returns partial or empty Wikidata block
- No LEI record found for private or non-registered entities
- SEC EDGAR lookup fails if ticker is missing or company is not a US public filer
- Domain registration data unavailable for certain TLDs or privacy-protected registrations
- Tech stack detection returns empty if domain is behind heavy obfuscation or CDN
- HTTP 402 Payment Required if wallet has insufficient USDC balance
- Timeout if upstream data sources (Wikidata, EDGAR, WHOIS) are slow

## How this service works

Bundled execution of the Entity enrichment workflow - Company name → verified identity + web footprint dossier: Wikidata facts, the official LEI legal-entity record, the SEC EDGAR filer, domain registration, tech stack, and brand favicon - in one pass. One x402 payment runs 6 underlying tools (wikidata-entity, lei-lookup, edgar-company-lookup, whois, tech-stack, favicon-grab); partial-success per step.

## Output

A structured dossier containing verified Wikidata facts, the official LEI legal-entity record, SEC EDGAR filer profile (if applicable), WHOIS/domain registration details, detected web tech stack, and brand favicon — all aggregated from a single company name/domain/ticker input.
