MethodGET
Operationget_event_tag.js
AuthAuthorization: Bearer $HANZO_API_KEY

Serves the browser tag that autocaptures pageviews (initial and SPA) and uncaught errors onto the canonical wire at POST /v1/event.

Install is one line, and it is the same line for a Hanzo property and for a customer's own page:

<script defer src="https://api.hanzo.ai/v1/event/tag.js" data-key="pk-…"></script>

data-key is the publishable key the project mints; data-product optionally names the emitting surface. The key may also ride the src as ?key= for a host that strips data attributes.

WITHOUT A KEY THE TAG SENDS NOTHING. A keyless beacon is accepted 200 into $public, a reserved tenant the owning org cannot read — so silence is the honest failure, and the tag picks it rather than reporting success into a tenant nobody reads.

Request

GET /v1/event/tag.js takes no parameters and no body — the credential is the whole request.

Examples

hanzo event tag.js
import { Configuration, EventApi } from 'hanzoai';

const api = new EventApi(new Configuration({ accessToken: process.env.HANZO_API_KEY }));
const { data } = await api.getEventTagJs();
from hanzoai.cloud import ApiClient, Configuration
from hanzoai.cloud.api import EventApi

client = ApiClient(Configuration(access_token=os.environ["HANZO_API_KEY"]))
result = EventApi(client).get_event_tag_js()
cfg := hanzoai.NewConfiguration()
cfg.AddDefaultHeader("Authorization", "Bearer "+os.Getenv("HANZO_API_KEY"))
client := hanzoai.NewAPIClient(cfg)

resp, _, err := client.EventAPI.GetEventTagJs(context.Background()).Execute()
if err != nil {
	return err
}
use hanzo_client::apis::{configuration::Configuration, event_api};

let mut cfg = Configuration::new();
cfg.bearer_access_token = std::env::var("HANZO_API_KEY").ok();

let result = event_api::get_event_tag_js(&cfg, Default::default()).await?;
import ai.hanzo.cloud.ApiClient;
import ai.hanzo.cloud.api.EventApi;

ApiClient client = new ApiClient();
client.setBearerToken(System.getenv("HANZO_API_KEY"));

var result = new EventApi(client).getEventTagJs();
curl https://api.hanzo.ai/v1/event/tag.js \
  -H "Authorization: Bearer $HANZO_API_KEY"

MCP reaches event through the event tool, which names its 9 operations with its own verbs — this one among them, under a name only MCP declares. describe explains any of them:

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": "get_event_economic"
         }
       }
     }'
