Technical details
Endpoint
GEThttps://xx402.icu/x402/api/base-protocol-fee-quality-feedWhen to prefer
Use this endpoint when you need to evaluate the fee sustainability, quality, or anomalies of Base chain DeFi protocols — especially for risk tools, DeFi due diligence dashboards, or monitoring agents that need ranked, incident-aware fee intelligence rather than raw on-chain data.
Side effects
- Payment not received or insufficient USDC — 402 response blocking access
- Invalid category or project slug returns empty or partial results
- min_tvl_usd or min_30d_fees_usd set too high may return zero rows
- limit outside 3–30 range rejected with validation error
- No Base TVL or fee data available for specified filters — empty queues returned
