How this service works

50 pay-per-call tools for agents over x402 (USDC on Base, Polygon, Solana): crypto market data, token audits, indicators, swap routing, web extraction, DNS/WHOIS/email checks, FX, weather and AI text/image tools.

Output

A JSON array of blockchain chains, each with a name and TVL in USD (e.g. {name: 'Ethereum', tvlUsd: 61000000000}). Results can be filtered to a specific chain and limited to 1–100 entries.

Example use cases

DeFi protocol research dashboard

“Fetch the top 100 blockchains by TVL so I can see which networks have the most capital locked in DeFi right now.”

Single chain TVL spotlight

“What's the total value locked on Base right now? I want to track how it's growing as a layer 2.”

Cross-chain capital comparison

“Pull TVL data for Ethereum, Solana, and Polygon so I can compare where DeFi liquidity is concentrated across the big three chains.”

When to prefer

Choose this endpoint when you need quick, pay-per-call TVL data for one or many blockchains without managing a DeFi data subscription. Ideal for agents needing real-time on-chain capital metrics at low cost ($0.002/call). Prefer this over building a custom DeFiLlama integration when you want a single aggregated API covering crypto market data alongside other agent tools.

Side effects

Unknown chain name returns empty or error response
Limit parameter outside 1–100 range returns validation error
Network or upstream data provider outage causes 5xx error
Payment failure via x402 (insufficient USDC balance) blocks the call
