# Graph Advocate — Uniswap Pre-Trade Analysis

> Graph Advocate — Uniswap Pre-Trade Analysis is a paid API for AI agents from graphadvocate.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-13).

Runs an onchain pre-trade intelligence query against Uniswap subgraph data, returning token price, liquidity, buy/sell flow, honeypot risk, and a tradeable verdict for a given token or pair.

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 graph-advocate-uniswap-pre-trade-analysis-fcfa319f -d '<json body>'
```

Example prompt: Before I swap into WETH, run a Uniswap pre-trade check on it — I need the current price, buy/sell flow, honeypot risk, and the best liquidity pool to use.

## When to prefer this

Use this endpoint when you need a fast, structured pre-trade intelligence report for a Uniswap token without writing GraphQL yourself. It covers honeypot risk, liquidity quality, directional trend, and venue selection in a single paid call ($0.02 USDC). Prefer it over raw subgraph queries when you need a synthesized verdict rather than raw rows, or when you want Claude to handle subgraph routing across 15,500+ indexed datasets automatically.

## Known failure modes

- Token not indexed in any subgraph — returns no matching subgraph error
- Ambiguous token symbol resolves to wrong contract — returns incorrect data
- Chain not supported — returns unsupported chain error
- Payment of $0.02 USDC not completed — query not executed, free-tier response returns subgraph and GraphQL only
- Subgraph data stale — liquidity or price may lag real-time CEX prices
- Low liquidity token — TVL and flow data may be sparse or zero

## How this service works

Uniswap pre-trade due-diligence. POST {token, chain?, version?}. Returns real_liquidity + deepest venue (ranked by volumeUSD, NEVER TVL — Uniswap subgraph TVL is inflated by spam pools), alternate fee-tier venues, a two-way-flow honeypot check over recent swaps, daily volume trend, and a composed verdict {tradeable, risk, reasons}. Covers Uniswap V2/V3/V4 on Ethereum, Arbitrum, Base, Polygon, Optimism, BSC. For agents sizing or vetting a spot position before they touch a token.

## Output

Returns a JSON object with: token symbol and price in USD; buy/sell flow counts and two-way flag; honeypot risk level (low/medium/high); trend direction and percent change versus 3-day average; best venue pair with TVL in USD, fee tier, and real liquidity flag; and an overall risk/tradeable verdict.
