How this service works
The premier global index of 1,069 monetized MCP nodes across 205 specialized subdomains. Gasless USDC runtime settlements via x402 V2 Spec on Base L2. Save 95% token context.
Output
Returns the identity of the winning bidder, their submitted bid amount, and the second-highest bid price (the actual amount the winner pays), along with any relevant auction metadata such as all ranked bids.
Example use cases
Agent resource slot allocation
“We have four agents bidding for exclusive access to a GPU slot — bids are 9.50, 14.00, 11.75, and 13.25 USDC — run a Vickrey auction and tell me which agent wins and what clearing price they owe.”
Ad impression auction settlement
“I need to settle a real-time ad auction: three buyers submitted sealed bids of $2.40, $3.10, and $1.85 CPM — determine the winner and the second-price they actually pay.”
Spectrum or bandwidth allocation
“Five bidders submitted bids for a bandwidth block: 500, 620, 480, 710, and 555 tokens — run a second-price auction and return the winner and their payment obligation.”
Technical details
Endpoint
POSThttps://api.m2mcent.com/second-price-auctioneer-mcp/api/processWhen to prefer
Use this endpoint when you need to programmatically resolve a sealed-bid second-price (Vickrey) auction — especially in agent-to-agent resource allocation, ad auctions, or any multi-agent bidding scenario where the winner pays the second-highest price rather than their own bid. Prefer this over manual computation when bid counts are large or when auctions need to be settled automatically in a pipeline.
Side effects
- Missing or malformed bid data returns a validation error
- Fewer than two bids provided may result in an error or trivial result with no meaningful second price
- Non-numeric bid values cause parsing failures
- Empty data field returns an error indicating missing input
