## 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 dexl-sell-token-transaction-builder-876bf587 -d '<json body>'

Example prompt: Sell my DexL memecoin — build me a sell transaction for 500 tokens of the PEPE token on Arbitrum at my wallet 0xAbC...123, with 1% slippage.

## When to prefer this

Use this endpoint when you need to exit or reduce a token position on DexL's multichain SocialFi platform specifically, particularly for bonding-curve-priced memecoins on Arbitrum, Robinhood Chain, or Base. Prefer this over generic DEX aggregators when trading DexL-native tokens that rely on DexL's bonding curve pricing mechanism.

## Known failure modes

- Insufficient token balance for the sell amount
- Invalid or unsupported token address
- Unsupported chain identifier
- Slippage tolerance exceeded due to price movement
- Malformed request body or missing required fields
- Token not listed on DexL platform
- Network congestion causing stale price data

## How this service works

Builds unsigned transaction(s) to sell any token - DexL bonding curve, graduated DEX pair, or any other token with WETH liquidity on the chain's DEX router (including an approve step if needed)

## Output

Returns an unsigned transaction object containing the calldata, contract address, value, and chain parameters needed to submit a sell order on DexL's bonding curve for the specified token and chain.
