insider_cluster_brief

What is insider_cluster_brief?

insider_cluster_brief is a paid work product in the Finance & Crypto category on agenttoll.dev. It costs $0.10 per call, settled in USDC on Base via the x402 payment protocol. No API keys or accounts: your agent inspects the metadata, explains the expected result, caps the spend, calls the tool, and receives structured JSON with a receipt envelope.

Input parameters

Only send these request-body fields. If this block is empty, send {}.

{
  "ticker": "optional stock ticker",

}

Request body

{
  "ticker": "AAPL",
  "limit": 30
}

HTTP endpoint

POST JSON to this URL. The first unpaid call returns HTTP 402 with x402 payment requirements; an x402-capable client signs and retries.

https://agenttoll.dev/paid/finance/insider-cluster-brief

MCP call

Connect an MCP client to the endpoint, call tool insider_cluster_brief, and pass the request body as arguments.

https://agenttoll.dev/mcp

MCP paid-tool calls may surface the payment challenge inside the JSON-RPC result instead of as a raw HTTP 402.
