How this service works
Pay-per-call stock, macro, on-chain, and crypto data over the x402 protocol. USDC on Base or Solana, no API keys, no subscriptions.
Output
A JSON object containing the protocol's canonical name, slug, token symbol, current TVL in USD, market cap in USD, 1-day and 7-day TVL percentage changes, and a ranked list of top chains by TVL with individual chain TVL values. Data is timestamped with an as_of field.
Example use cases
DeFi protocol research for investment
“Can you pull up Aave's current TVL, market cap, and which chains are holding the most liquidity? I want to see if it's growing or shrinking over the past week.”
Cross-chain TVL distribution check
“Show me how Curve Finance's total value locked is distributed across Ethereum, Arbitrum, and other chains right now.”
DeFi dashboard monitoring
“Give me a snapshot of Uniswap's on-chain metrics — TVL, market cap, and the 1-day and 7-day TVL change — I'm tracking it for my portfolio.”
Technical details
Endpoint
GEThttps://x402-stock-indicators.vercel.app/defi-protocol/%7Bslug%7DWhen to prefer
Choose this endpoint when you need real-time DeFi protocol TVL and market cap data without setting up an API key or subscription — ideal for AI agents that can pay $0.01 USDC per call via the x402 protocol on Base or Solana. Prefer this over traditional data APIs when you want frictionless, pay-as-you-go access to on-chain DeFi metrics including multi-chain TVL breakdowns.
Side effects
- Unknown or misspelled slug returns 404 or empty result
- Protocol not indexed by the data provider returns no data
- x402 payment failure if wallet has insufficient USDC on Base or Solana
- Stale data if the underlying data provider hasn't refreshed recently
- Rate limiting or provider outage causing 5xx errors
