AI Fin Hub for Agents

Route money questions to the right tool without guessing inputs. 90+ deterministic finance calculators across 11 categories — Savings & Investing, Debt & Credit, Housing, Tax, Insurance, Budgeting, Retirement, FIRE & Independence, Freelancer & Gig, Expat & Global, and Life Transitions.

CORS enabled — call from anywhere
Deterministic results cached 1 hour
Input parameter names use snake_case

How agents should use this hub

Preferred: Call /api/{slug}/?params and read the JSON result directly.

For discovery, start with agent-tools.json, then map the user goal to the exact tool slug.

Each tool's contract URL has the input schema and a sample payload. Use snake_case query params matching the contract fields.

Do not scrape labels or flip modes to learn inputs — read the contract JSON instead.

Human + agent routing

People should start at homepage use cases, the Decision Engine, or All Tools. Agents should start from discovery manifests and move straight to contracts.
