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 hosaka-company-dossier-43bd9f3a -d '<json body>'
```

Example prompt: Pull a full company dossier for stripe.com — I want every third-party vendor you can detect from their DNS records and scripts, plus their registrar, mail provider, certificate info, and site facts.

## When to prefer this

Choose this endpoint when you need deep, proof-backed technographic intelligence — every vendor claim is supported by a specific DNS record or script, not just inferred. It is preferable over lightweight lookup endpoints (like Hosaka's fast company look-up sibling) when you need the full vendor dependency map, not just top-level domain facts. Ideal for sales intelligence, competitive research, security audits, or due diligence workflows where evidence matters and you do not have a paid technographics subscription.

## Known failure modes

- Domain not found or does not resolve — empty or error response
- Private/obscured registration data limits registrar details
- Domain uses aggressive DNS TTL or proxying (e.g. Cloudflare) that hides some vendor signals
- Script-based vendor detection limited to publicly accessible pages
- Newly registered or parked domains may yield sparse results
- Payment failure via x402 protocol returns 402 before dossier is generated

## How this service works

Company data for AI agents, paid per call in USDC. Reads a company's own DNS to find every third-party vendor it can be proven to use, and returns the record proving each one.

## Output

A structured dossier containing: a list of every detectable third-party vendor with the DNS record or script that proves their presence, domain registration details (registrar, age), mail provider, DNS provider, DMARC configuration, HTTPS/TLS certificate facts, and general site metadata.
