f1owUTC Anchor
The current UTC instant, so your agent can fix what “now” means and judge for itself how stale a read is.
What it does
Returns the current UTC time in ISO 8601 format. Use it to anchor 'now' — e.g. to judge how stale a generatedAt timestamp or news date is.
Parameters
None — call it with empty arguments.
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/time" \
-H "Authorization: Bearer $F1OW_API_KEY"{
"jsonrpc": "2.0",
"id": 1,
"method": "tools/call",
"params": {
"name": "utc_time",
"arguments": {}
}
}const res = await fetch("https://mcp.f1ow.com/v1/time", {
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/time",
headers={"Authorization": f"Bearer {os.environ['F1OW_API_KEY']}"},
)
data = res.json() # the tool's result as JSON, typed in the OpenAPI spec
print(data)// wss://mcp.f1ow.com/v1/ws — subprotocol "jsonrpc-2.0", Authorization: Bearer <key>
{
"jsonrpc": "2.0",
"id": 1,

}Sample response
A real response captured 2026-11-13. JSON is what REST and WebSocket return, and the structuredContent of an MCP call (trimmed for length), with generatedAt for freshness. Text is the report an MCP client hands to a model.
