# Screen a wallet (KYT)

> Paid crypto-address screen before a send or after a mystery block. Report only — does not gate deposit.

# Screen a wallet (KYT)

Agents can **check a crypto address for dirt** (sanctions / mixer exposure) with spend MCP. Use this **before** you accept a TRC-20 credit, or **after** a wallet is blocked and the reason is unclear — screen the counterparty from the tx.

This is a **paid report**. It does **not** gate TRON deposit credit. It does **not** ban or unblock anyone. IMBA decides any follow-up. Channel is off unless IMBA enabled Didit for Agent API.

Not Partner `/api/partner/kyt_*`. Not human `/api/client/kyt_*`. Not a Visa PAN screen. TON is not in this catalog.

## When

| Moment                                | What to pass                                                                  |
| ------------------------------------- | ----------------------------------------------------------------------------- |
| Before a send / inbound               | The **source** TRON address you expect, or the address a human will send from |
| Before you tell a human where to send | The destination they care about (external wallet), `network` + `address`      |
| After a mystery block                 | The **counterparty** address from the transaction, then read the report       |

## MCP / HTTP

1. `kyt_quote` — `POST /api/kyt_quote`. Price. Debit is **not** here.
2. `kyt_check` — `POST /api/kyt_check` with `network` (`tron_usdt` | `eth` | `btc`) and `address`. Debits \~0.99 USDT from ledger **2401**.
3. Poll `kyt_check_get` — `POST /api/kyt_check_get` with `id` until the report is ready.
4. `kyt_checks` — own history.

Never pass `client_id`. Space calls \~1s (`catalog_gap`).
