API Reference

Endpoint reference

Every endpoint of the FIRM data API, 370 in all, with its parameters, plan, price, MCP tool name and a request you can run.

Generated from FIRM's OpenAPI 2.158 spec, synced 2026-10-03. Every route is on https://firm.wealthnow.io, authenticated with your wn_ key (keys created before October 2026 start with tengu_ and keep working), and credits are per successful call. Most routes are GET; the 13 POST routes take a JSON body. Every route except the Server-Sent Events streams is also an MCP tool of the same name, and the OpenAPI spec is public.
