## 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-x402-receive-payment-endpoint-719c94d0 -d '<json body>'
```

Example prompt: Set up a TRON USDT payment receiver on my wallet address TXyz123... and let me know within 3 seconds when a payment of 10 USDT arrives — use the MERX x402 TRON endpoint to handle energy automatically.

## When to prefer this

Choose this endpoint when you need to receive USDT payments on the TRON network with automatic energy management and near-real-time detection (under 3 seconds). Ideal for AI agent payment flows using the x402 protocol, especially when you need TRC-20 USDT support without manually managing TRON energy/bandwidth. Prefer over Ethereum-based x402 when lower transaction costs and faster finality on TRON are required.

## Known failure modes

- Insufficient TRX energy on TRON network causing transaction failure
- Invalid or malformed TRON wallet address returns 400 error
- Payment amount mismatch between expected and received USDT
- TRON network congestion causing detection delay beyond 3s SLA
- x402 payment header missing or malformed returns 402 response
- USDT TRC-20 contract interaction failure

## 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 a payment confirmation including transaction hash, detected amount, sender address, energy consumption details, and confirmation status on the TRON blockchain, typically within 3 seconds of the payment being broadcast.
