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
A JSON response with a 'data' object containing aggregated yield information, a 'status' field ('ok' on success), and an 'roi_proof' object including a compression_ratio_pct (e.g. 91.4%) demonstrating the efficiency of the yield data aggregation.
Example use cases
Stablecoin yield comparison
“What's the best yield available for USDC right now across DeFi protocols? Show me the ROI proof too.”
ETH staking yield lookup
“Can you look up the current yield aggregator results for ETH and tell me the compression ratio on the ROI proof?”
DeFi asset return research
“I'm researching yield opportunities for WBTC — can you fetch the latest aggregated yield data and ROI summary for that asset?”
Technical details
Endpoint
GEThttps://mcp-gateway.agentdiet.dev/v1/yield-aggregator?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need aggregated DeFi yield data with an on-chain ROI proof for a specific asset, paid per-call via x402/USDC on Base. Prefer it over manual protocol queries when you want a single normalized response across 30,000+ MCP-connected data sources without managing multiple API integrations.
Side effects
- Missing or invalid 'asset' query parameter returns incomplete data
- Payment not settled in USDC on Base results in 402 payment required error
- Unsupported asset ticker returns empty or null data object
- Gateway overload or upstream MCP routing failure returns non-ok status
- Malformed input object (missing 'type' or 'method') returns schema validation error
