TokenLedger

AI cost and behavior snapshots for .NET apps that use IChatClient.

Record the model's responses once and replay them in CI for free; measure calls, tokens and tool calls per test scenario; compare them with a baseline committed to the repository and fail on regressions or budgets. Prices are yours to configure. Works with any Microsoft.Extensions.AI provider, streaming included.

// The chat client: TokenLedger last, closest to the provider. Outside a test scenario it does nothing.
services.AddChatClient(inner).UseFunctionInvocation().UseTokenLedger();

// A test, in any framework:
await using var ledger = Ledger.Scenario("support-chat/order-status");
var answer = await chat.GetResponseAsync("Where is my order 42?");
ledger.Budget(maxCalls: 3, maxTokens: 4_000);
// Disposing the scenario compares the calls with tokenledger/baselines/support-chat/order-status.json.

TOKENLEDGER_MODE = auto (default on your machine), replay (default in CI), record or live. TOKENLEDGER_UPDATE=1 accepts the current measurements.

TokenLedger.AspNetCore

TokenLedger for ASP.NET Core integration tests: attributes each model call to the HTTP endpoint that made it (POST api/support/chat makes 3 calls), so baselines and pull request reports show the cost per endpoint, and connects the requests of a test to its scenario with WebApplicationFactory, TestServer or a real host.
