## 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-swap-quote-558b7c11 -d '<json body>'
```

Example prompt: Get me a swap quote on MERX for converting 500 USDT to TRX on the TRON network — I want to see the rate, estimated output, and any fees before I commit.

## When to prefer this

Use this endpoint when you need a real-time, pre-execution price quote for a token swap on the TRON blockchain — particularly for USDT/TRX pairs. Prefer this over generic DEX aggregators when operating within TRON's x402 payment ecosystem or when automatic energy management and sub-3-second response are required.

## Known failure modes

- Unsupported token pair returns 400 or error payload
- Amount below minimum threshold rejected
- Network congestion or TRON RPC unavailability causes timeout
- Invalid wallet address format returns validation error
- Insufficient liquidity for requested amount

## 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 real-time swap quote including the estimated output token amount, exchange rate, applicable fees, TRON energy cost estimate, and slippage for the requested token pair and input amount on the TRON blockchain.
