EXACT CONTRACTS · NO ACCOUNT · PAY PER ANSWER

Connect once.
Choose by decision.

The fastest path is MCP: add one remote endpoint, call recommend_tool for free, then let the agent choose among eight paid decision tools. Direct HTTP is available when you need an explicit route and request contract.

WORKS WHERE AGENTS WORK

Add one remote server.

Connection and free tool discovery require no account. Paid calls require an x402-capable wallet or client; the agent sees the exact USDC price before it decides whether to sign.

CODEX

Settings → MCP servers

Add a Streamable HTTP server named Anyway Possible, paste the endpoint below, save, and restart.

[mcp_servers.anyway-possible]
url = "https://anywaypossible.com/api/mcp"
CLAUDE CODE

One command

Add the remote HTTP server at user scope, then run claude mcp list to confirm it is connected.

claude mcp add --transport http --scope user anyway-possible https://anywaypossible.com/api/mcp
CURSOR

Settings → Tools & MCP

Add a custom MCP server or paste this entry into your MCP configuration.

{
  "mcpServers": {
    "anyway-possible": {
      "url": "https://anywaypossible.com/api/mcp"
    }
  }
}
ANY MCP CLIENT

Streamable HTTP

Use the public endpoint directly. Initialize the server, list tools, and call recommend_tool free before a paid tool.

https://anywaypossible.com/api/mcp

Important: Connecting exposes the tools, but it does not give the agent spending authority. Paid execution only works when its client can answer an x402 payment challenge with a funded Base USDC wallet.

Start free. Pay only for evidence.

Describe the decision to recommend_tool. It returns the best tool, exact price, required inputs, alternatives, and next step without triggering payment. Every paid request below is generated from the same product catalog as the machine-readable OpenAPI and JSON catalog.

Payment stays under agent control.

The first HTTP request returns the exact price, network, asset, recipient, and timeout. The agent signs only when those terms match its policy. Payment Guard can perform the final validation immediately before signing another x402 purchase.
