RentRollAPI.Client
Official .NET client for RentRollAPI — convert commercial real estate rent rolls (PDF, Excel, CSV, scans) into structured, verified data with one call.
Every extraction includes a deterministic verification report: totals recomputed from extracted units are reconciled against the totals stated on the document, unit counts are cross-checked, and any uncertain field is flagged with a confidence score — never silently guessed.
Install
dotnet add package RentRollAPI.Client
Quick start
using RentRollApi.Client;
using var client = new RentRollClient("rr_live_your_key");
var result = await client.ExtractAsync("rent-roll.pdf");
Console.WriteLine($"{result.PropertyName?.Value}: {result.Units.Count} units");
Console.WriteLine($"Confidence: {result.Verification.DocumentConfidence:P0}, all checks passed: {result.Verification.AllChecksPassed}");
foreach (var unit in result.Units)
Console.WriteLine($" {unit.UnitNumber?.Value,-8} {unit.TenantName?.Value,-24} {unit.MonthlyRent?.Value,10:C}");
foreach (var check in result.Verification.Checks)
Console.WriteLine($" [{check.Result}] {check.Name}: {check.Detail}");
Excel / CSV output
byte[] xlsx = await client.ExtractToXlsxAsync(fileStream, "rent-roll.pdf");
string csv = await client.ExtractToCsvAsync(fileStream, "rent-roll.pdf");
T12 / operating statements
var t12 = await client.ExtractOperatingStatementAsync("t12.pdf");
Console.WriteLine($"{t12.PropertyName?.Value} — {t12.Months.Count} months, {t12.LineItems.Count} line items");
foreach (var item in t12.LineItems)
Console.WriteLine($" [{item.Kind,-8}] {item.Label?.Value,-30} {item.Total?.Value,12:C} ({item.Category})");
Console.WriteLine($"All checks passed: {t12.Verification.AllChecksPassed}");
ExtractOperatingStatementToXlsxAsync / ExtractOperatingStatementToCsvAsync return file output, mirroring the rent-roll methods.
With IHttpClientFactory
services.AddHttpClient("rentroll", c => c.Timeout = TimeSpan.FromMinutes(5));
var client = new RentRollClient(httpClientFactory.CreateClient("rentroll"), apiKey);
Error handling
try
{
var result = await client.ExtractAsync("statement.pdf");
}
catch (RentRollApiException ex) when (ex.StatusCode == HttpStatusCode.UnprocessableEntity)
{
Console.WriteLine(ex.Message);
}
catch (RentRollApiException ex) when ((int)ex.StatusCode == 429)
{
}
MCP server (AI assistants)
RentRollAPI also runs a hosted Model Context Protocol server — no install required. Point any MCP-capable client (Claude, Cursor, VS Code Copilot, ...) at the streamable-HTTP endpoint and it gains an extract_rent_roll tool:
{
"mcpServers": {
"rentrollapi": {
"type": "http",
"url": "https://rentrollapi.com/mcp",
"headers": { "X-Api-Key": "rr_live_your_key" }
}
}
}
