How this service works
Pay-per-call crypto microdata for trading/onchain AI agents via x402 (USDC on Base): Base gas, token risk, balances, multi-venue prices, Hyperliquid book/funding, kimchi premium. No API keys.
Output
Returns a JSON object with: global DeFi TVL and 1d/7d/30d percentage changes, a flow label (flat/inflow/outflow), a directional signal (e.g. NEUTRAL), per-chain data for the requested chain (TVL, rank, chain ID, date), a ranked list of top chains, human-readable reasons array, data source URL, timestamp, and suggested next endpoint paths.
Example use cases
DeFi market health check for trading bot
“Before executing my DeFi trade, pull the current total DeFi TVL, the 7-day flow trend, and the overall market signal so I know if conditions are favorable.”
Base chain TVL monitoring
“What is Base's current TVL in USD, its rank among all chains, and how has it changed over the past 7 and 30 days?”
Top chains leaderboard for portfolio dashboard
“Show me the top 20 DeFi chains ranked by TVL with their share percentages and 7-day changes — I want to see where liquidity is concentrated right now.”
Technical details
Endpoint
GEThttps://kr-x402-mvp.kgy5612.workers.dev/v1/defi-overview?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs a broad DeFi market snapshot — total TVL, chain rankings, and flow signals — in a single no-API-key call paid by USDC micropayment. Prefer it over full DefiLlama API integration when you want ultra-low-cost pay-per-use access without account setup, or when the agent needs a pre-digested signal (NEUTRAL/BULLISH/BEARISH) rather than raw data. Best for onchain trading agents, portfolio dashboards, and market-condition checks before executing DeFi transactions.
Side effects
- Unknown chain name returns empty or null chain object
- Invalid protocol slug returns no protocol-specific data
- Limit out of range (>50 or <1) returns validation error
- Payment failure via x402 returns 402 with payment details
- Stale data if DefiLlama upstream is delayed
- Workers.dev cold start may add latency on first call
