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: chain-level TVL in USD, rank, share of total DeFi, 1d/7d/30d percentage changes, flow direction (flat/up/down), an overall DeFi market summary (total TVL, counts, period changes), a directional signal (NEUTRAL/BULLISH/BEARISH), human-readable reasons, a top-chains leaderboard array, source attribution, timestamp, and suggested next endpoints.
Example use cases
Pre-trade DeFi health check
“Before I deploy liquidity on Base, can you pull the current TVL, 7-day change, and DeFi signal for Base so I know if it's a good environment to enter?”
Protocol TVL due diligence
“I'm evaluating Aave — can you get me the current TVL data and DeFi market signal for that protocol so I can assess its activity level?”
Top chains TVL leaderboard
“Give me a ranked list of the top 15 chains by DeFi TVL with their share percentages and 7-day changes, so I can see where liquidity is concentrated right now.”
Technical details
Endpoint
GEThttps://kr-x402-mvp.kgy5612.workers.dev/v1/crypto/protocol?utm_source=zero.xyzWhen to prefer
Choose this endpoint when your agent needs structured, signal-ready DeFi TVL data for on-chain decision-making — particularly for Base ecosystem analysis. Prefer it over raw DefiLlama API calls when you want a pre-digested directional signal, don't want to manage API keys, and are comfortable with x402 USDC micropayments. Best for trading agents, liquidity deployment logic, and protocol research workflows.
Side effects
- Unknown chain name returns empty or error response
- Invalid protocol slug returns no protocol data
- x402 payment failure blocks the response (402 Not Authorized)
- Data may lag by minutes to hours depending on DefiLlama refresh cadence
- limit parameter out of range (must be 1–50) returns validation error
