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 a status field ('ok'), a data object containing slippage estimates, and an roi_proof object including a compression_ratio_pct value (e.g. 91.4%), indicating how efficiently the route compresses or settles the transaction.

Example use cases

Pre-flight slippage check for token route

“I'm about to send a GET request through the x402 broker using token 'usdc-base-v1' — can you estimate the slippage first so I know if this route is efficient?”

ROI validation before MCP server call

“Before my agent calls that MCP server endpoint via POST, estimate the slippage and give me the ROI proof so I can decide if it's worth the $0.01 fee.”

Comparing route efficiency for agent workflow

“I need to compare slippage on a GET vs POST route through the x402 broker for my token — can you run the slippage estimator for the GET method and tell me the compression ratio?”

Endpoint

When to prefer

Use this endpoint when you need to estimate slippage or verify route efficiency before committing to an x402-brokered API or MCP server call, especially when optimizing cost or validating ROI on USDC-settled transactions on Base. Prefer this over generic fee estimators when working within the X402-Broker ecosystem with its 31,000+ MCP server routes.

Side effects

Missing required 'input' object returns validation error
Invalid method value (not GET or POST) returns schema error
Unknown or malformed token parameter may return empty data object
Network or gateway timeout if broker is under load
Payment failure if USDC balance is insufficient for the $0.01 fee
