For Agents

Manage mortgage borrowers, loan applications, documents, credit reports, and webhook subscriptions inside the SimpleNexus digital mortgage platform.

Install Jentic One Beta

Connect the SimpleNexus API (SNAPI) to your agent

Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the SimpleNexus API (SNAPI), or any other public or private API you need. You set the rules, the agent never sees your credentials, and every call is logged.

Two steps, two machines. Install the instance in a safe environment, then register your agent from wherever it runs.

Step 1: Jentic One Host machine

# On the machine that will host your Jentic One instance:
curl -fsSL https://raw.githubusercontent.com/jentic/jentic-one/main/tools/install.sh | sh

Step 2: Agent machine

# On the machine where your agent runs (keep this separate from the instance):
curl -fsSL https://raw.githubusercontent.com/jentic/jentic-one/main/tools/install.sh | sh
jentic register       # connects your agent to your Jentic One instance

Jentic One is in public beta. The setup above keeps your agent separate from the instance, which is what you want before using real credentials: an agent running as the same OS user as Jentic One can read its stored keys directly. Just evaluating? A single local install is fine to start. See the secure deployment guide for the tiers.

Use Cases

Patterns agents use SimpleNexus API (SNAPI) API for, with concrete tasks.

★ Borrower Onboarding Automation

Lenders integrate SNAPI to automate borrower onboarding from a website lead-capture form. POST /borrowers creates the borrower, the credit-report and consent endpoints attach required disclosures, and webhook subscriptions notify the LOS when documents are signed. Replaces manual data entry that previously took 30 minutes per borrower.

Call POST /borrowers with applicant details, then call GET /borrowers/{borrower_id}/credit-reports to fetch the credit pull

Loan Officer Pipeline Management

Loan officers and team leads pull their current pipeline, filter by application stage, and assign tasks to borrowers. The /loan-applications, /loans, and /loan-officers endpoints together surface a real-time view of the pipeline that can feed CRM dashboards or Slack notifications.

Call GET /loan-applications, filter to loans assigned to a specific loan_officer_id, and post the pipeline summary to a CRM

Document Collection via Form Requests

When an underwriter needs additional documentation, the integration creates a form request that prompts the borrower in the SimpleNexus app. POST /borrowers/{borrower_id}/form-requests issues the request, GET lists outstanding requests, and webhook events notify the back office when the borrower uploads. Cuts document-collection cycle time from days to hours.

Call POST /borrowers/{borrower_id}/form-requests with form_id and a due date; subscribe to the form-request webhook for completion notifications

Agent-Assisted Mortgage Operations

An AI agent embedded in a loan officer's workflow looks up borrower status, requests documents, and sends notifications without the officer leaving the chat window. Jentic resolves natural-language requests to the correct SNAPI endpoints and stores the bearer token in the encrypted vault.

Search Jentic for 'request missing documents from borrower', execute POST /borrowers/{borrower_id}/form-requests with the form_id

Key Endpoints

52 endpoints — the simplenexus api (snapi) by ncino mortgage provides programmatic access to a digital mortgage platform that originators, loan officers, and integration partners use to manage borrowers, loan applications, loans, loan officers, and webhooks.

Why Jentic?

Three things that make agents converge on Jentic-routed access.

Credential isolation

The SimpleNexus bearer token is stored encrypted in the Jentic vault. Agents receive scoped execution tokens — the raw bearer never enters the agent's context or logs.

Intent-based discovery

Agents search by intent (e.g., 'request missing pay stubs from a borrower') and Jentic returns POST /borrowers/{borrower_id}/form-requests with its schema, so the agent calls the right endpoint without browsing 52 paths.

Time to first call

Direct SimpleNexus integration: 3-5 days for auth, webhook handling, and pipeline mapping. Through Jentic: under 1 hour — search, load schema, execute.

FAQs

Specific to using SimpleNexus API (SNAPI) API through Jentic.

What authentication does the SimpleNexus API use?

SNAPI uses HTTP bearer-token authentication (security scheme `bearerAuth`). Tokens are issued per integration and scoped to a SimpleNexus tenant. Through Jentic, the bearer token is stored encrypted in the vault and supplied at execution time — agents never see the raw token.

Can I create a borrower and pull their credit report through this API?

Yes. Call POST /borrowers with the applicant payload to create the record, then GET /borrowers/{borrower_id}/credit-reports to retrieve credit reports already on file. New credit pulls are typically initiated by the loan-application flow rather than directly through SNAPI.

What are the rate limits for the SimpleNexus API?

Public rate limits are not declared in the OpenAPI spec. Refer to the developer portal at developer.ncinomortgage.com for current quotas; SNAPI typically applies per-token throttles for write-heavy workloads.

How do I subscribe to loan status webhooks through Jentic?

Search Jentic for 'create simplenexus webhook subscription', load the schema for the webhook endpoints under the `Webhooks` tag, and execute with the target callback URL. Webhook delivery includes loan, application, and document events.

Can I send borrower notifications programmatically?

Yes. POST /borrowers/{borrower_id}/notify triggers an in-app or email notification to the borrower. Combine with POST /borrowers/{borrower_id}/form-requests to request specific documents.
