> Token Pool Comparison and Snapshot Changes is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-28).

Compares up to ten Base or Solana DEX token pools using free DEX Screener data, optionally diffing against a user-supplied prior snapshot to surface price, liquidity, and availability changes.

## 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 token-pool-comparison-and-snapshot-changes-e3323ed7 -d '<json body>'
```

Example prompt: Can you pull the current DEX Screener pool data for Solana token So11111111111111111111111111111111111111112 and compare it against the snapshot I gave you earlier to show me what changed in price and liquidity?

## When to prefer this

Choose this endpoint when you need a cheap ($0.01 USDC), lightweight snapshot-and-diff of DEX pool data for a specific Base or Solana token, especially when you already hold a prior snapshot and want to surface changes in price range or liquidity. It is not a substitute for verified historical data, whale tracking, or safety/audit signals — use it for quick agent-side polling and change detection in automated DeFi workflows.

## Known failure modes

- Token address not found on DEX Screener — empty or null pool list returned
- Invalid or unsupported chain value — validation error
- Token address too short or too long — schema validation failure
- DEX Screener upstream unavailable — downstream fetch error
- Previous snapshot format mismatch — comparison may partially fail or return null diffs

## How this service works

Token Pool Comparison and Snapshot Changes: Compare up to ten reported Base or Solana token pools using free DEX Screener data. Optionally compare with a supplied previous snapshot. Includes timestamps, price range, liquidity and missing values. Prior data is customer supplied; no verified historical, whale or safety claim. 0.01 USDC includes one bounded crypto-data report.

## Output

Returns a bounded crypto-data report containing up to ten DEX pool entries for the specified token, including timestamps, price range, liquidity figures, and flags for missing pools. When a previous snapshot is supplied, the response includes a diff highlighting changes between the prior and current data. Costs 0.01 USDC per call.
