# Scout Packs Email Pattern Lookup

> Scout Packs Email Pattern Lookup is a paid API for AI agents from scout-packs-production.up.railway.app, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-11).

Analyzes a company domain to infer its corporate email address pattern (e.g. {first}.{last}@acme.com) along with MX record status and catch-all detection.

## 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 scout-packs-email-pattern-lookup-6b73467f
```

Example prompt: What email pattern does acme.com use for their employees — like first.last or firstinitial.last — and do they have valid MX records?

## When to prefer this

Choose this endpoint when you need to infer the email naming convention for a specific company domain before constructing or validating B2B contact emails. It is especially useful for sales automation and outreach agents that need to guess individual email addresses from a known name and domain, without requiring a full contact database subscription. Prefer this over general email verification tools when the goal is pattern discovery rather than validating a specific known address.

## Known failure modes

- Domain not recognized or too obscure to infer a pattern — patterns array returns empty
- No MX records found — mx_found returns false
- Domain is a catch-all — catch_all_unknown returns true, making pattern-based guessing unreliable
- Payment not completed via x402 — 402 response returned before data is delivered
- Invalid or malformed domain query parameter — request rejected

## How this service works

Verified B2B lead packs and per-lead enrichment lookups for agents. $0.01 per lookup or pack (demand probe). USDC on Base via x402. No account, API key, or subscription.

## Output

Returns the company domain, detected email address patterns (e.g. '{first}.{last}'), whether MX records were found, whether the domain is a catch-all, and any additional signals — all as JSON.
