Verified student-loan math, in your product or your AI agent

Finology Software exposes its parity-verified federal calculation engine two ways: a REST API for your product, and an MCP server for AI agents. Both are calculation-only, provenance-stamped, and kept current as the federal rules change.

Apply for access

MCP server Available now

For AI agents and assistants

Connect any MCP client over Streamable HTTP and call the same engine advisors use. Your agent gets verified projections it can cite, instead of math it made up.

https://mcp.finology.tech/mcp
  • run_projection one verified projection under one plan
  • compare_scenarios compare 2–10 scenarios
  • get_eligible_plans eligible plans per loan
  • get_plan_types accepted plan-type strings

Auth: X-Api-Key header · Server card · auth.md

REST API Preview

For your product

Call the planning engine from your own backend and render the results in your own UI. Documented with OpenAPI, versioned under /v1.

https://api.finology.tech
  • POST /v1/projection one verified repayment projection
  • POST /v1/comparison compare scenarios
  • POST /v1/plan-eligibility eligible plans per loan
  • GET /v1/me your account and tier

In preview: keys are issued case by case while we finalize general availability. OpenAPI docs · auth.md

One credential covers both surfaces: the same key authenticates against the REST API and the MCP server, with a shared usage quota. Tell us which you want to start with in the application below.

How access works
STEP 1

Apply

Fill out the short application below: who you are, what you want to build, and which surface you need.

STEP 2

We review and issue a key

We review every application by hand and reply by email, usually within two business days, with a key and a usage tier that fits your volume.

STEP 3

Authenticate and build

Send your key in the X-Api-Key header on every request. Verify it any time with GET /v1/me.

The engine is calculation-only by design. No client personal data is read or accepted: every loan and scenario number travels in the request, and every result is stamped with its provenance and rule version.

Tell us what you want to build. We read every application and reply by email.

Looking for the embeddable calculators instead? Those are included with an advisor Pro seat and take one line of code: see the calculators page. Running a firm that wants the whole platform under its own brand? See Powered by Finology Software.

The REST API is in preview and not yet generally available. Calculations are estimates for planning, not financial advice. Powered by Finology Software.
