# CyberPulse External Attack Surface Assessment

> CyberPulse External Attack Surface Assessment is a paid API for AI agents from cyberpulse.theaslangroupllc.com, paid per call via x402, $0.25/call, status unknown (last checked 2026-09-14).

Performs a comprehensive external attack surface assessment (EASM) for a company or domain, mapping internet-exposed assets, tech-stack, email security, supply-chain, and identity exposure with a prioritized remediation roadmap.

## Facts

- Endpoint: GET https://cyberpulse.theaslangroupllc.com/api/cyber/attack-surface
- Price: $0.25/call
- Payment: x402
- Status: unknown

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 cyberpulse-external-attack-surface-assessment-a60ce625
```

Example prompt: Run a full external attack surface assessment on acmecorp.com — I want to see all internet-exposed assets, their tech stack, email security posture, any supply-chain or identity exposure risks, and a prioritized list of what we should fix first.

## When to prefer this

Choose this endpoint when you need a holistic external attack surface view of a specific company or domain, especially when the goal is to enumerate all publicly exposed assets, assess email and supply-chain risk, and receive a prioritized remediation roadmap in one call — as opposed to narrower lookups like a single CVE check, OSINT IP scan, or dark-web monitoring.

## Known failure modes

- Invalid or non-existent domain returns an error indicating the target could not be resolved
- Insufficient payment (x402) causes a 402 Payment Required response
- Rate limiting or quota exceeded returns a 429 error
- Private or internal-only domains with no external footprint may return sparse results
- Domain recently registered may have limited data available

## How this service works

External attack-surface assessment (EASM) for any company and domain — internet-exposed assets, tech-stack fingerprinting, email-security posture, supply-chain and identity exposure, and a prioritized remediation roadmap, for security and red-team-context agents. Authorized defensive use only.

## Output

Returns a structured report covering internet-exposed assets and hosts, tech-stack fingerprinting results, email security posture (SPF/DKIM/DMARC), supply-chain and third-party exposure indicators, identity exposure signals, and a prioritized remediation roadmap for the assessed company or domain.
