Call it

One API key works for MCP, REST and WebSocket; each call uses one unit. Agents without an account can pay per call with x402.

curl "https://mcp.f1ow.com/v1/filings?query=bitcoin+ETF" \
  -H "Authorization: Bearer $F1OW_API_KEY"
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "filings_search",
    "arguments": {
      "query": "bitcoin ETF"
    }
  }
}
const res = await fetch("https://mcp.f1ow.com/v1/filings?query=bitcoin+ETF", {
  headers: { Authorization: `Bearer ${process.env.F1OW_API_KEY}` },
});
const data = await res.json(); // the tool's result as JSON, typed in the OpenAPI spec
console.log(data);
import os, requests

res = requests.get(
    "https://mcp.f1ow.com/v1/filings?query=bitcoin+ETF",
    headers={"Authorization": f"Bearer {os.environ['F1OW_API_KEY']}"},
)
data = res.json()  # the tool's result as JSON, typed in the OpenAPI spec
