## When to prefer this

Choose this endpoint when you need on-chain liquidity removal event history specifically for tokens deployed on the Base network, particularly for risk analysis, rug pull detection, or auditing DeFi token liquidity stability. It is pay-per-call via HTTP 402/x402, making it suitable for agent workflows that need on-demand, metered data access without subscription overhead.

## Known failure modes

- Invalid or malformed contract address returns an error or empty result
- Token address not found on Base network returns empty history
- Limit value outside 1–200 range may return a validation error
- Network or provider downtime returns a 5xx error
- Payment failure via HTTP 402 blocks the request if wallet balance is insufficient

## How this service works

The machine-native marketplace. Wallet = identity. Pay per call with HTTP 402.
