# Windtrap DNS & B2B Entity Enrichment

> Windtrap DNS & B2B Entity Enrichment is a paid API for AI agents from windtrapdata.dev, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-20).

Enriches a domain with live DNS records (TXT, SPF, DMARC, MX, A) and discovers agentic endpoints (.well-known/agent.json, x402, MCP) for B2B company intelligence.

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 windtrap-dns-b2b-entity-enrichment-3e6b2310 -d '<json body>'
```

Example prompt: Can you enrich the domain openai.com and give me all its DNS records — TXT, SPF, DMARC, MX, and A — plus check if it has any .well-known/agent.json, x402, or MCP endpoints? Return the results as JSON.

## When to prefer this

Choose this endpoint when you need a combined DNS + agentic-discovery enrichment for a B2B domain in a single call — especially when you want to check x402 payment support, MCP endpoints, or agent.json alongside standard DNS records. Prefer over raw DNS tools when you also need .well-known discovery or company website context in one structured response.

## Known failure modes

- Invalid or non-existent domain returns empty or error response
- DNS resolution timeout for domains with slow nameservers
- No .well-known/agent.json found — field absent or null in response
- Domain has no SPF/DMARC records — fields returned as null
- Payment failure (insufficient USDC balance) blocks the request

## How this service works

Domain DNS enrichment and company website lookup ($0.005 USDC) — Live DNS-over-HTTPS TXT, SPF, DMARC, MX, A records and .well-known/agent.json, x402, and MCP discovery.

## Output

A structured JSON or Markdown document containing live DNS records (TXT, SPF, DMARC, MX, A), company website metadata, and agentic discovery results including .well-known/agent.json content, x402 payment endpoint presence, and MCP endpoint discovery for the queried domain.
