SecureLend SDK for Python

The official Python SDK for SecureLend - Financial services infrastructure for AI assistants.

Lender outcomes

Comparison stays on https://mcp.securelend.ai/mcp. Outcomes, credit box, feedback, and webhooks use https://securelend.ai.

client = SecureLend(api_key=os.environ.get("SECURELEND_API_KEY"))
await client.record_outcome(lead_id, {
    "state": "declined",
    "reasonCode": "dscr",
})
header = client.sign_outcome_payload(raw_body, secret)

A decline without reasonCode, and a funded outcome without an amount and date, raise ValidationError before the request. A flag that is off raises FeatureDisabledError.

Installation

pip install securelend

Quick Start

import asyncio
import os
from securelend import SecureLend

async def main():
    # The API server is public and does not require an API key.
    # A key can optionally be provided for usage tracking.
    async with SecureLend(api_key=os.environ.get("SECURELEND_API_KEY")) as securelend:
        response = await securelend.compare_business_loans({
            "loanAmount": 200000,
            "purpose": "equipment",
            "annualRevenue": 1200000,
        })

        print(f"Found {response.summary.total_offers} loan offers.")

        if response.offers:
            top_offer = response.offers[0]
            apr = top_offer.terms.interest_rate.apr * 100
            print(f"Top offer from {top_offer.lender.name} with {apr:.2f}% APR.")

            # Calculate payment details for the top offer
            payment_details = await securelend.calculate_loan_payment({
                "loanAmount": top_offer.terms.amount.amount,
                "interestRate": apr,
                "loanTermInMonths": top_offer.terms.term_months,
            })
            print(f"  - Estimated Monthly Payment: ${payment_details.monthly_payment:,.2f}")
