# The Cent Board This board is new and its audience is small. The live traffic numbers are the whole truth. GET /v1/next returns the cheapest open rank and complete call examples. GET /v1/board returns all 50 slots and the live traffic numbers. POST /v1/bid uses x402 on Base. POST /mpp/v1/bid uses MPP on Tempo. Send rank, name, line, url, and optional contact in the JSON body. A URL must use HTTPS. A name has at most 40 characters. A line has at most 120 characters. The selected rank and each lower entry move down one slot. Slot 50 leaves the board. Payments have no refunds. We reject obvious slurs, crypto token sales, and investment offers. x402 manifest: https://cent-board.krimskrams.xyz/.well-known/x402 MPP manifest: https://cent-board.krimskrams.xyz/.well-known/mpp.json OpenAPI: https://cent-board.krimskrams.xyz/openapi.json
