How this service works
Pay-per-request crypto market data API for AI agents. 16 endpoints on Base Mainnet via x402 protocol. No accounts, no API keys. USDC micropayments from $0.001. Works with Claude Desktop, ElizaOS, and any MCP client.
Output
Volatility metrics for the requested cryptocurrency asset, such as historical or implied volatility values, returned as a JSON response after a $0.001 USDC micropayment is processed via the x402 protocol on Base Mainnet.
Example use cases
Risk assessment for DeFi position sizing
“Before I deposit into this Solana pool, check how volatile SOL is right now. Use AgentData to get the volatility metrics — I'll pay the tiny USDC fee from my Base wallet.”
Multi-asset volatility comparison for portfolio
“Compare the current volatility across Bitcoin, Ethereum, and my favorite altcoin so I can decide which one to hedge. Hit AgentData for all three and show me the metrics.”
Real-time market risk monitoring for trades
“I'm about to execute a large trade on this token. Pull its latest volatility data from AgentData first so I know what risk I'm taking on — use my Base wallet to cover the lookup cost.”
