Specification
Specification pending — no HIP in hanzoai/hips declares capability: function yet. What this capability serves is below, from the API document; what it is — the store it owns, how it meters, what it publishes — is written as a HIP under HIP-0139.
Four surfaces
| Surface | Reaches this capability as | Coverage |
|---|---|---|
| REST | function at its own prefix | 11 operations |
| CLI | hanzo function … | 11 of 11 |
| SDK | — | no published client declares one yet — regenerating the clients is what adds them |
| MCP | tool functions on https://api.hanzo.ai/v1/mcp | 10 operations, 1 under the document's own id — ask describe for the rest |
Quickstart
export HANZO_API_KEY=sk-... # console.hanzo.ai → API keysThen the first call — a read that needs nothing but the key. GET /v1/function, operation get_function:
hanzo function listimport { Configuration, FunctionApi } from 'hanzoai';
const api = new FunctionApi(new Configuration({ accessToken: process.env.HANZO_API_KEY }));
const { data } = await api.getFunction();from hanzoai.cloud import ApiClient, Configuration
from hanzoai.cloud.api import FunctionApi
client = ApiClient(Configuration(access_token=os.environ["HANZO_API_KEY"]))
result = FunctionApi(client).get_function()cfg := hanzoai.NewConfiguration()
cfg.AddDefaultHeader("Authorization", "Bearer "+os.Getenv("HANZO_API_KEY"))
client := hanzoai.NewAPIClient(cfg)
resp, _, err := client.FunctionAPI.GetFunction(context.Background()).Execute()
if err != nil {
return err
}use hanzo_client::apis::{configuration::Configuration, function_api};
let mut cfg = Configuration::new();
cfg.bearer_access_token = std::env::var("HANZO_API_KEY").ok();
let result = function_api::get_function(&cfg, Default::default()).await?;import ai.hanzo.cloud.ApiClient;
import ai.hanzo.cloud.api.FunctionApi;
ApiClient client = new ApiClient();
client.setBearerToken(System.getenv("HANZO_API_KEY"));
var result = new FunctionApi(client).getFunction();The method above is the one at the current release of the document. [email protected] (npm) was generated from an earlier release, where this operation carried a different id, so it spells the method differently — regenerating the clients is what makes the two agree.

Endpoints
| Endpoint | What it does |
|---|---|
GET /v1/function/{name}/invocations | Is one function's past runs, newest first — each with its status, HTTP code, method, time and duration. |
POST /v1/function/{name}/invoke | Runs a function and records a REAL invocation. |
GET /v1/function/{name}/logs | Is the output of a function's most recent run — its error text when that run failed, else what it printed. |
GET /v1/function/{name} | Is one function with everything a detail page needs in one round-trip: its definition, its 7-day rollup, its trigger, its twenty most recent… |
DELETE /v1/function/{name} | Removes one of the caller org's functions and answers 204. |
GET /v1/function/deployments | Is what is live right now — each function's current record IS its live deployment, so this is the deployment inventory. |
GET /v1/function/metrics | Is the org's serverless dashboard over a window: a per-function invocation costLine and how those invocations ended. |
GET /v1/function/secrets | Is the NAMES of the secrets the caller org's functions mount. |
GET /v1/function/triggers | Is what calls the caller org's functions — one row per function. |
GET /v1/function | Is every serverless function the caller's org has published, each with its real 7-day rollup. |
POST /v1/function | Publishes a serverless function under the caller's org and answers 201 with it. |
