# Changelog

> A record of API and platform changes, additions, and deprecations.

All notable changes to the 9Squid API are documented here. The API follows semantic versioning. Breaking changes are always announced with a deprecation period before removal.

***

## v1.0 — April 2026

### Added

* **Platform API Gateway** — Unified entry point for all Originator and Investor workflows under a single base URL (`https://api.9squid.com/v1/api`) with a consistent response envelope.

* **Originator Loan Management** — Full loan tape submission lifecycle: initiate, upload, complete, and status tracking across `DRAFT` → `IN_REVIEW` → `QC_COMPLETED` → `APPROVED` / `REJECTED`.

* **Bulk Loan Upload** — Submit multiple loan tapes in a single job. Each deal gets its own pre-signed upload URL with independent status tracking.

* **Selection Criteria** — Trigger eligibility runs against underwriting rules. Results include per-loan pass/fail status and exception detail.

* **Deal Marketplace** — Investor-facing deal listing with tranche details, filtering, and sorting.

* **Investor Subscriptions** — IOI submission, subscription commitment, and allocation tracking.

* **Investor Portfolio Reports** — Holdings, trade history, tranche performance metrics, and pool analytics in a unified endpoint.

* **ALM Analytics** — Duration, convexity, NII sensitivity, EVE, VaR, and stress testing on any deal via the TCT Risk ALM engine.

* **Pool Analytics** — Aggregate pool statistics: weighted averages, delinquency breakdown, geographic distribution.

* **Deal Room Documents** — Document upload support for W9 forms and supporting deal materials.

* **Webhooks** — Real-time event delivery for deal status changes, loan approvals, trade settlements, SC completions, and document uploads. Includes signature verification and delivery replay.

* **Role-Based Access Control** — Originator and Investor roles enforced at the token level. Cross-role requests return `403 Forbidden`.

* **Secondary Market Trading** — Endpoints for listing, bidding on, and settling secondary market trades.
