## 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 agentkyb-business-counterparty-check-aef826b2 -d '<json body>'
```

Example prompt: Before we pay Acme Solutions Ltd at acmesolutions.com, run a counterparty check on them — I need to know if they clear sanctions screening, whether their domain matches their legal entity, and whether I should allow, review, or block the payment.

## When to prefer this

Choose this endpoint when an AI agent needs a pre-transaction due diligence signal on a business counterparty — especially before executing a payment — and requires a single, consolidated allow/review/block recommendation combining legal entity resolution, sanctions screening, and domain consistency in one call. Prefer this over manual lookup tools or individual sanctions-check APIs when speed and multi-source corroboration matter for agentic payment workflows.

## Known failure modes

- Unknown or unresolvable business name returns inconclusive evidence
- Domain not found in RDAP returns missing domain evidence
- Network timeout or upstream data source unavailability returns error
- Ambiguous company names with multiple matches may return low-confidence results
- Sanctioned entity detected triggers block recommendation

## How this service works

Pre-transaction business counterparty check for AI agents. Combines legal-entity resolution, cross-source corroboration, sanctions screening, RDAP domain evidence and domain/company-name consistency into one compact evidence result. Decision support only; not legal or transaction approval.

## Output

Returns a compact evidence result with an action-oriented recommendation (allow, review, or block), legal entity resolution details, cross-source corroboration data, sanctions screening outcome, RDAP domain ownership evidence, and a company-name/domain consistency assessment.
