Headers

X-FormulaSignal-Origin'api' | 'mcp'

Optional attribution: mcp when the call comes from the FormulaSignal MCP server, api otherwise. Self-reported and recorded on the usage row so a customer can see which surface their traffic came from. Nothing reads it to decide what a caller may do, so a wrong value costs only the accuracy of that customer's own reporting.
