Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

apideck-dotnet scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Apideck .NET SDK Skill

Overview

The Apideck Unified API provides a single integration layer to connect with 200+ third-party services across accounting, CRM, HRIS, file storage, ATS, e-commerce, and more. The official .NET SDK (ApideckUnifySdk) provides typed clients for all unified APIs.

Installation

dotnet add package ApideckUnifySdk

IMPORTANT RULES

  • ALWAYS use the ApideckUnifySdk NuGet package. DO NOT make raw HttpClient calls to the Apideck API.
  • ALWAYS pass apiKey, appId, and consumerId when initializing the client.
  • USE ServiceId to specify which downstream connector to use (e.g., "salesforce", "quickbooks").
  • USE async/await for all API calls — all operations return Task<T>.
  • ALWAYS handle errors with try/catch using BaseException as the base class.
  • DO NOT store API keys in source code. Use environment variables or a secrets manager.

Quick Start

using ApideckUnifySdk;
using ApideckUnifySdk.Models.Requests;

var sdk = new Apideck(
    consumerId: "your-consumer-id",
    appId: "your-app-id",
    apiKey: Environment.GetEnvironmentVariable("APIDECK_API_KEY") ?? ""
);

var res = await sdk.Crm.Contacts.ListAsync(new CrmContactsAllRequest {
    ServiceId = "salesforce",
    Limit = 20,
});

while (res != null)
{
    foreach (var contact in res.GetContactsResponse?.Data ?? [])
    {
        Console.WriteLine($"{contact.Name} - {contact.Emails?.FirstOrDefault()?.Email}");
    }
    res = await res.Next!();
}

SDK Patterns

Client Setup

using ApideckUnifySdk;

var sdk = new Apideck(
    consumerId: "your-consumer-id",
    appId: "your-app-id",
    apiKey: Environment.GetEnvironmentVariable("APIDECK_API_KEY") ?? ""
);

CRUD Operations

All resources follow the pattern: sdk.{Api}.{Resource}.{Operation}Async(request).

using ApideckUnifySdk;
using ApideckUnifySdk.Models.Requests;
using ApideckUnifySdk.Models.Components;

// LIST
var listRes = await sdk.Crm.Contacts.ListAsync(new CrmContactsAllRequest {
    ServiceId = "salesforce",
    Limit = 20,
    Filter = new ContactsFilter { Email = "[email protected]" },
    Sort = new ContactsSort {
        By = ContactsSortBy.UpdatedAt,
        Direction = SortDirection.Desc,
    },
});

// CREATE
var createRes = await sdk.Crm.Contacts.CreateAsync(new CrmContactsAddRequest {
    ServiceId = "salesforce",
    Contact = new ContactInput {
        FirstName = "John",
        LastName = "Doe",
        Emails = new List<Email> {
            new Email { EmailAddress = "[email protected]", Type = EmailType.Primary },
        },
        PhoneNumbers = new List<PhoneNumber> {
            new PhoneNumber { Number = "+1234567890", Type = PhoneNumberType.Mobile },
        },
    },
});
Console.WriteLine(createRes.CreateContactResponse?.Data?.Id);

// GET
var getRes = await sdk.Crm.Contacts.GetAsync(new CrmContactsOneRequest {
    Id = "contact_123",
    ServiceId = "salesforce",
});

// UPDATE
var updateRes = await sdk.Crm.Contacts.UpdateAsync(new CrmContactsUpdateRequest {
    Id = "contact_123",
    ServiceId = "salesforce",
    Contact = new ContactInput { FirstName = "Jane" },
});

// DELETE
await sdk.Crm.Contacts.DeleteAsync(new CrmContactsDeleteRequest {
    Id = "contact_123",
    ServiceId = "salesforce",
});

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
