# Score a domain 0-100 across six identity dimensions

`POST /v1/payg/identity-risk-score`

## Request

- Base URL: `https://api.relayshield.net`
- URL: `https://api.relayshield.net/v1/payg/identity-risk-score`
- Auth: none required

Return a 0-100 domain security score across 6 identity-risk dimensions (breach exposure, infostealer density, ransomware exposure, session exposure, CVE exposure, threat-actor targeting) with a letter grade and plain-English risk factors. Call as a single-number identity health check before onboarding, financing, or partnering with a domain.

**Billing.** $0.35 in USDC per call over x402, on Base or Solana. No API key, no signup and no
subscription. Send the request with no payment header, take the `402` challenge that comes back,
pay it, and repeat the request. Only successful calls are charged.

## Request body

- object
  - `domain` string, required: Root domain to score

## Response `200`

Payment settled and the check ran. `ok` is true and `data` holds the result.

- object
  - `ok` true, required
  - `data` object, required

## Other responses

- `400`: A required field is missing or malformed. Never billed.
- `402`: Payment required. The body carries a complete x402 version 2 challenge with the accepted networks, the amount in USDC base units, and the recipient. Pay it and repeat the request with the payment header.
- `405`: Wrong HTTP method. Every endpoint is POST.
