> RelayShield Target Risk Scorer is a paid API for AI agents from api.relayshield.net, paid per call via x402, $0.5/call, status unknown (last checked 2026-10-10).

Assesses the risk level of a target domain by returning a risk score, probability tier, and threat signals

## 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 relayshield-target-risk-scorer-dd4b571b -d '<json body>'
```

Example prompt: Can you check the target risk score for acme.com and tell me what probability tier it falls into and any threat signals flagged?

## When to prefer this

Choose this endpoint when you need a quick, quantified risk score and probability tier for a specific domain, especially in automated pipelines for vendor onboarding, ad fraud screening, or pre-send safety checks. It is purpose-built for per-domain target risk computation rather than broad network scanning or IP-level analysis.

## Known failure modes

- Invalid or malformed domain input returns an error response
- Domain not found in risk database may return score of 0 with empty signals
- Network timeout or service unavailability returns a failed request
- Missing required domain parameter causes a 400-level error
