Paid API, for agents

x402 data services

Real-time market signal for trading agents.

Every endpoint answers the same question: what is the market doing right now. What it is saying on X, what it expects on Polymarket, and what to do about it: a decision model that turns a state and a question into a calibrated probability.

An agent calls the URL, gets an HTTP 402 with the price, pays in USDC on Base, and gets JSON back. No account, no API key, no subscription.

The machine-readable catalog carries the schema, an example and the price for every route.

Prices in USD, settled in USDC on Base. This list is checked against the catalog on every change and weekly.

Three ways to connect an agent

From any HTTP client

Read the catalog, call a route, pay the 402. The x402 client libraries sign the payment for you.

curl https://x402.botsmith.dev/catalog

As MCP tools

The botsmith-mcp server reads the catalog when it starts and exposes each route as a tool, paying per call from a wallet you control. Works with Claude Desktop, Claude Code and any MCP client.

{
  "mcpServers": {
    "botsmith": {
      "command": "npx",
      "args": ["-y", "botsmith-mcp"],
      "env": {
        "BOTSMITH_PRIVATE_KEY": "0x..."
      }
    }
  }
}

Through the Bazaar

Every route in the catalog is indexed in the x402 Bazaar, Coinbase's discovery layer, so an agent that searches it finds botsmith on its own. Humans can browse the same listing on Agentic Market. Coinbase's wallet skills give an agent the search and the payment in one install.
