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 auction outcome including the winning bidder, the winning bid amount, and the clearing price (i.e. the second-highest bid) that the winner must pay, based on Vickrey/second-price auction rules.
Example use cases
Automated ad slot auction settlement
“I have three advertisers bidding on a display ad slot — Advertiser X bid $4.20, Advertiser Y bid $3.80, and Advertiser Z bid $5.10. Run a second-price auction and tell me who wins the slot and how much they actually pay.”
NFT Vickrey auction result
“We held a sealed-bid auction for our NFT drop. The bids came in at 2.5 ETH, 3.1 ETH, 1.8 ETH, and 2.9 ETH. Process these as a second-price auction and return the winner and the clearing price.”
Procurement reverse auction evaluation
“We're running a reverse Vickrey auction for a supply contract — the lowest bidder wins but pays the second-lowest price. Bids are: Supplier A $12,000, Supplier B $9,500, Supplier C $11,200. Process this and tell me the winner and what price they'll receive.”
Technical details
Endpoint
POSThttps://api.m2mcent.com/second-price-auction-host-mcp/api/processWhen to prefer
Use this endpoint when you need to automate the settlement of a second-price (Vickrey) sealed-bid auction, particularly in multi-agent or programmatic bidding environments where fairness and incentive-compatibility of the pricing mechanism matter. Prefer over custom logic when you want a hosted, stateless auction evaluation service.
Side effects
- Malformed or missing bid data returns an error
- Fewer than two valid bids provided may cause undefined auction behavior
- Non-numeric bid values cause processing failure
- Tied bids may produce ambiguous winner determination
- Timeout if data payload is too large
