# MPT issuance risk — full issuer detail (x402, $0.01 USDC on Base or RLUSD on XRPL)

`GET /api/x402/usdc/mpt/{issuanceId}`

## Request

- Base URL: `https://www.xrplhub.io`
- URL: `https://www.xrplhub.io/api/x402/usdc/mpt/{issuanceId}`
- Auth: none declared

Everything /api/mpt/{issuanceId} returns plus the parts that cost real live work: issuer account age, blackhole check, xrp-ledger.toml domain verification, the full credential list, and a `related` cross-sell block (all live ledger reads). x402 exact scheme, USDC on Base via the CDP facilitator. No signup.

## Path parameters

- `issuanceId` string, required

## Response `200`

Full risk view — see /api/mpt/{issuanceId} 200 schema plus issuerRisk.{accountAgeDays,blackholed,domain,domainVerified,credentials} and a related[] block.

## Other responses

- `402`: Payment Required — x402 challenge. Pay EITHER in USDC on Base (v1 body; retry with X-PAYMENT) OR in RLUSD on the XRP Ledger (v2: PAYMENT-REQUIRED header, network xrpl:0; retry with PAYMENT-SIGNATURE, result wrapped as { data, x402 }).
