# AgentDiet DEX Screener Proxy

> AgentDiet DEX Screener Proxy is a paid API for AI agents from mcp-gateway.agentdiet.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-22).

Fetches DEX token pair data from DexScreener via a metered x402-payment gateway, returning market data for a given token.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 agentdiet-dex-screener-proxy-20b37291
```

Example prompt: Pull the DEX Screener data for the token at address 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 — I want to see its current price, liquidity, and active trading pairs.

## When to prefer this

Use this endpoint when you need on-chain DEX market data (prices, liquidity, trading pairs) for a specific token address and are operating in an x402/USDC micropayment environment. Prefer this over direct DexScreener API calls when you need metered, agent-friendly pay-per-call access settled on Base without managing API keys.

## Known failure modes

- Invalid or missing token parameter returns empty or error data
- Token not found on any DEX returns empty data object
- Payment failure (insufficient USDC) results in HTTP 402 response
- Gateway or DexScreener upstream outage returns error status
- Malformed query parameters cause request rejection

## How this service works

Deterministic B2A/A2A/MCP/x402/MPP/L402 execution and intelligence node at https://mcp-gateway.agentdiet.dev settling in USDC on Base.

## Output

Returns a JSON object with status 'ok' and a data field containing DEX pair information for the queried token (price, liquidity, volume, trading pairs, etc.), sourced from DexScreener and compressed through the gateway.
