## 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 411data-io-web-research-business-enrichment-3b63677c -d '<json body>'
```

Example prompt: Can you look up public contact info for Apex Roofing Solutions in Austin, Texas — I need their phone numbers, key people with titles, address, and any attorneys or registered agents associated with them for outreach compliance?

## When to prefer this

Choose this endpoint when you need managed, web-researched enrichment for a business entity and require not just basic contact data but also key personnel with titles and legal associates (attorneys, registered agents) for compliance-aware outreach. It is preferable over directory-only lookups when the target company may not be in structured databases, and over person-search endpoints when the primary query entity is a business rather than an individual.

## Known failure modes

- No match found — business name too ambiguous or not indexed publicly (no charge on no-match)
- Partial match — some fields returned but others unavailable due to sparse web presence
- Rate limit or quota exceeded — API returns an error requiring retry
- Invalid input — missing required business name field returns a validation error
- Vendor upstream failure — web research provider unavailable causing a timeout or error response

## How this service works

Managed web-research enrichment: given a business name (+ optional city/state/domain), find public phones, people (name+title), addresses, and legal_associates (attorneys, registered agents, family counsel) for outreach compliance. $1.00 minimum on match; vendor COGS above $1 billed at 30% markup. Bill-on-match.

## Output

Returns a structured record for the matched business including: public phone numbers, named individuals with their titles, physical addresses, and legal associates such as attorneys, registered agents, and family counsel. Billed at $1.00 minimum on a successful match; vendor costs above $1 are passed through at 30% markup.
