Every number is the ledger, aggregated the one way the books define it, never a guess; it is the grounded read the unified /v1/ask advisor replays. ## Request 3 fields. | Field | In | Type | Required | Description | | --------- | ----- | ------ | -------- | ----------------------------------------------------------------- | | `sandbox` | query | string | — | Sandbox reads the org's SANDBOX ledger when it is exactly "true". | | `from` | query | string | — | From is the RFC3339 start of the window, exclusive. | | `to` | query | string | — | To is the RFC3339 end of the window, inclusive. | ## Response | Status | Body | Meaning | | --------- | --------------------- | ------- | | `200` | books.MetricsResponse | ok | | `default` | problem-details | refused | `200` body — 20 fields. | Field | In | Type | Always | Description | | ------------------ | ---- | --------------- | ------ | ------------------------------------------------------------------------------------------------------------ | | `arr` | body | integer (int64) | — | ARR is annualized recurring revenue in cents (MRR × 12). | | `burn` | body | integer (int64) | — | Burn is total expense in cents over the period. | | `cash` | body | integer (int64) | — | Cash is the bank + processor-clearing balance in cents as of To. | | `cogs` | body | integer (int64) | — | COGS is cost of goods sold in cents over the period. | | `deferredRevenue` | body | integer (int64) | — | DeferredRevenue is the customer-wallet liability in cents as of To. | | `figures` | body | books.Figure\[] | — | Figures is the same snapshot rendered through books' one money formatter. | | `figures[].label` | body | string | — | Label names the metric, e.g. "MRR" or "Runway". | | `figures[].period` | body | string | — | Period is the window the figure covers, e.g. "2026-07" or "all-time". | | `figures[].value` | body | string | — | Value is the figure already formatted through books' own money formatter, so a consumer never re-derives it. | | `from` | body | string | — | From is the RFC3339 start of the reporting window, exclusive; absent for all time. | | `grossMarginBps` | body | integer (int64) | — | GrossMarginBps is GrossProfit / Revenue in basis points (7000 = 70%). | | `grossProfit` | body | integer (int64) | — | GrossProfit is Revenue − COGS, in cents. | | `monthlyBurn` | body | integer (int64) | — | MonthlyBurn is net cash burned per month in cents; 0 when not losing cash. | | `months` | body | integer (int64) | — | Months is the window length in whole months used to normalize MRR and burn. | | `mrr` | body | integer (int64) | — | MRR is monthly recurring revenue in cents. | | `netIncome` | body | integer (int64) | — | NetIncome is Revenue − Burn, in cents. | | `period` | body | string | — | Period is the human window label, e.g. "2026-07" or "all-time". | | `revenue` | body | integer (int64) | — | Revenue is recognized revenue in cents over the period. | | `runwayMonths` | body | integer (int64) | — | RunwayMonths is Cash / MonthlyBurn; -1 means infinite (the org is not burning). | | `to` | body | string | — | To is the RFC3339 end of the reporting window, inclusive; absent for up to now. | Failure carries the platform error shape — see [Errors](https://docs.hanzo.ai/docs/errors). ## Examples **CLI** ```bash hanzo books metrics ``` **SDK** **.ts** ```ts import { Configuration, BooksApi } from 'hanzoai'; const api = new BooksApi(new Configuration({ accessToken: process.env.HANZO_API_KEY })); const { data } = await api.getBooksMetrics(); ``` **.py** ```python from hanzoai.cloud import ApiClient, Configuration from hanzoai.cloud.api import BooksApi client = ApiClient(Configuration(access_token=os.environ["HANZO_API_KEY"])) result = BooksApi(client).get_books_metrics() ``` **.go** ```go cfg := hanzoai.NewConfiguration() cfg.AddDefaultHeader("Authorization", "Bearer "+os.Getenv("HANZO_API_KEY")) client := hanzoai.NewAPIClient(cfg) resp, _, err := client.BooksAPI.GetBooksMetrics(context.Background()).Execute() if err != nil { return err } ``` **.rs** ```rust use hanzo_client::apis::{configuration::Configuration, books_api}; let mut cfg = Configuration::new(); cfg.bearer_access_token = std::env::var("HANZO_API_KEY").ok(); let result = books_api::get_books_metrics(&cfg, Default::default()).await?; ``` **.java** ```java import ai.hanzo.cloud.ApiClient; import ai.hanzo.cloud.api.BooksApi; ApiClient client = new ApiClient(); client.setBearerToken(System.getenv("HANZO_API_KEY")); var result = new BooksApi(client).getBooksMetrics(); ``` **HTTP** ```bash curl https://api.hanzo.ai/v1/books/metrics \ -H "Authorization: Bearer $HANZO_API_KEY" ``` **MCP** MCP reaches **books** through the `books` tool, which names its 20 operations with its own verbs — this one among them, under a name only MCP declares. `describe` explains any of them: ```bash curl -X POST https://api.hanzo.ai/v1/mcp \ -H "Content-Type: application/json" \ -d '{ "jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": { "name": "describe", "arguments": { "op": "list_book_accounts" } } }' ``` --- [Books API](https://docs.hanzo.ai/docs/openapi/books) · [All Hanzo APIs](https://docs.hanzo.ai/docs/openapi) · [Interactive reference](https://docs.hanzo.ai/docs/openapi/reference)
