Payment (x402)

The API speaks the x402 payment standard. The flow is three steps and works from any HTTP client:

(exact USDC amount, receiver address, chain)

1. GET any paid endpoint → HTTP 402 with a self-describing challenge

1. Send that USDC amount on Base to the listed receiver
2. Retry the call with the payment header → 200 with your data

No keys. No accounts. Prices from $0.003 per call (the cheapest route is GET /api/v1/signal). Settled in USDC on Base (chain 8453).

MCP (Model Context Protocol)

The API is exposed as an MCP server for Claude Desktop, Cursor, Continue, LangChain and any MCP-compatible client:

(JSON-RPC 2.0 — initialize, tools/list, tools/call, ping)

• SSE transport: https://kristo-intelligence-api.onrender.com/mcp/sse
• Streamable HTTP transport: POST https://kristo-intelligence-api.onrender.com/mcp

MCP tools:

Each tool advertises its x402 price inline, so an agent can decide and pay without reading docs.
