## 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 merx-tron-watch-wallet-transaction-monitor-a27e981d -d '<json body>'
```

Example prompt: Watch TRON wallet TUxxxxxx...xxxxxx for any incoming USDT payments and let me know within seconds when something arrives.

## When to prefer this

Use this endpoint when an AI agent needs to confirm receipt of a TRON USDT payment in near real-time (under 3 seconds), particularly in x402-style payment flows where an agent is waiting to verify that a counterparty has paid before proceeding. Prefer over generic blockchain explorers when low-latency detection and AI-agent-native design (x402 protocol) are required.

## Known failure modes

- Invalid or malformed TRON wallet address returns validation error
- Network congestion on TRON blockchain may delay detection beyond 3s SLA
- No activity detected returns empty or polling timeout response
- Payment of $0.01 USDC not included causes 402 Payment Required rejection
- Callback URL unreachable causes missed notification delivery

## How this service works

TRON payment infrastructure for AI agents. Send and receive USDT with automatic energy, monitor wallets with less than 3s detection, access real-time blockchain data. TRON x402 facilitator (first in coinbase/x402 ecosystem registry).

## Output

Returns transaction event data including USDT transfer amount, sender address, transaction hash, block number, and timestamp when a new incoming transaction is detected on the monitored TRON wallet, with detection latency under 3 seconds.
