How this service works
Deterministic B2A/A2A/MCP/x402/MPP/L402 execution and intelligence node at https://mcp-gateway.agentdiet.dev settling in USDC on Base.
Output
Returns a JSON object with status 'ok', a data payload containing Pendle PT yield information (rates/APYs per market or asset), and an roi_proof field with a compression ratio metric indicating data efficiency.
Example use cases
DeFi yield scouting for idle stablecoins
“What fixed yields can I get on Pendle right now for USDC? I want to see the current PT APY before I decide where to park my stablecoins.”
Comparing PT yields across assets
“Pull the Pendle PT yield data for all available assets so I can compare fixed income rates across ETH, stETH, and USDC markets.”
Monitoring Pendle yields for portfolio rebalancing
“Check the latest Pendle principal token yields — I need to know if rates have moved enough to justify rebalancing my fixed-rate DeFi position.”
Technical details
Endpoint
GEThttps://mcp-gateway.agentdiet.dev/v1/pendle-pt-yields?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need current fixed-rate yield data from Pendle Finance's Principal Token markets, especially when building DeFi yield comparison tools, portfolio dashboards, or automated rebalancing agents that need on-chain fixed income rate data. Prefer this over general DeFi aggregators when Pendle-specific PT yield granularity is required.
Side effects
- Invalid or unsupported asset ticker returns empty data or error
- Network timeout or upstream Pendle API unavailability results in non-ok status
- Payment not settled in USDC on Base leads to 402 rejection before data is returned
- Malformed query parameters may result in schema validation error
