How this service works
x402-native paid API tools for DeFi yields, protocol TVL, AI pricing, paid MCP calls, and web scraping.
Output
Returns a JSON object with the tool's output — e.g. a list of DeFi yield opportunities with APY and protocol details, TVL figures for one or more protocols, AI model cost-per-token comparisons, or scraped webpage content. Response structure varies by tool called.
Example use cases
Compare DeFi yield opportunities
“Use the 400860 Data API to call the defi_yields tool and show me which stablecoin pools have the highest APY right now across major DeFi protocols.”
Check protocol TVL for research
“Fetch the current total value locked for Aave and Uniswap using the 400860 Data API's protocol_tvl tool — I'm building a DeFi market overview report.”
Look up AI model pricing
“I need to compare API pricing for GPT-4o, Claude 3.5, and Gemini Pro — can you call the 400860 Data API with the ai_pricing tool and pull that for me?”
Technical details
Endpoint
POSThttps://api.400860.xyz/v1/mcp/callWhen to prefer
Choose this endpoint when you need micropayment-gated, agent-friendly access to DeFi yield data, protocol TVL, AI model pricing, or web scraping in a single MCP-style call. It is ideal for AI agents operating in Web3 contexts that already support x402 payment flows, and where per-call USDC pricing is preferable to subscription-based data APIs. Prefer alternatives if you need free data, traditional REST APIs without payment headers, or deeply historical on-chain data.
Side effects
- Invalid or unknown tool name returns an error object
- Missing required params for a specific tool causes a tool-level error
- Payment failure (x402) if USDC balance is insufficient — call is not executed
- Tool timeout if upstream data source is unavailable
- Malformed params object causes a validation error
