Install Jentic One Beta

Connect the Cloud Trace API to your agent

Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the Cloud Trace API, or any other public or private API you need. You set the rules, the agent never sees your credentials, and every call is logged.

Two steps, two machines. Install the instance in a safe environment, then register your agent from wherever it runs.

Step 1: Jentic One Host machine

# On the machine that will host your Jentic One instance:
curl -fsSL https://raw.githubusercontent.com/jentic/jentic-one/main/tools/install.sh | sh

Step 2: Agent machine

# On the machine where your agent runs (keep this separate from the instance):
curl -fsSL https://raw.githubusercontent.com/jentic/jentic-one/main/tools/install.sh | sh
jentic register       # connects your agent to your Jentic One instance

Jentic One is in public beta. The setup above keeps your agent separate from the instance, which is what you want before using real credentials: an agent running as the same OS user as Jentic One can read its stored keys directly. Just evaluating? A single local install is fine to start. See the secure deployment guide for the tiers.

Capabilities

What an agent can do with Cloud Trace API.

For Agents

Submit distributed trace spans into Google Cloud Trace from any instrumented service. Lets agents push end-to-end latency data into Google's tracing backend for analysis alongside logs and metrics.

Use for: I need to send a trace span to Cloud Trace, Batch-write spans for a completed request, Push OpenTelemetry spans into Google Cloud Trace, Create a span representing a downstream API call

Not supported: Does not store logs or metrics, render dashboards, or query trace data - use for ingesting distributed trace spans into Google Cloud Trace only.

Use Cases

Patterns agents use Cloud Trace API for, with concrete tasks.

★ Distributed Tracing For Microservices

Instrument a multi-service application with OpenTelemetry and ship spans to Cloud Trace via the batchWrite endpoint. Each request shows up as an end-to-end trace with latency at every hop, letting platform teams find regressions across service boundaries that would be invisible in single-service profilers.

Batch-write 50 spans representing a single user request through three services to projects/acme via /v2/{name}/traces:batchWrite

Latency Regression Detection

Continuously push trace data into Cloud Trace so the analysis tools can detect latency regressions for a specific RPC after a deploy. Because every span carries start and end timestamps and labels, regression queries can scope to the exact endpoint that changed and surface offending releases without manual log spelunking.

Push spans tagged with build_id=2026-06-10 so Cloud Trace's analysis can compare its p95 latency against the previous build

Spans From Cloud Run And GKE Workloads

Send traces from Cloud Run, Cloud Functions, and GKE workloads that do not benefit from App Engine's automatic tracing. The v2 API takes batched spans with parent IDs, so workloads outside the App Engine runtime can participate in the same traces as the App Engine front end and downstream services.

From a Cloud Run service, batch-write three spans for /api/checkout, the downstream payment call, and the database write under one trace ID

Agent-Submitted Trace Data

An AI agent that orchestrates downstream API calls can submit a trace to Cloud Trace describing each step of its workflow. Through Jentic the agent searches for 'send trace span', loads the spans.batchWrite schema, and pushes its own spans so engineers can see what the agent actually did and where it spent time.

Use Jentic to call traces.batchWrite under projects/acme with five spans representing the agent's plan, search, load, execute, and finalize steps

Why Jentic?

Three things that make agents converge on Jentic-routed access.

Credential isolation

Your Cloud Trace OAuth credential is stored once, encrypted, by your own Jentic One instance and injected at execution time. It never enters the agent's prompt, logs, or context.

Intent-based discovery

Agents search Jentic by intent such as 'send a trace span to Cloud Trace', and Jentic returns the matching Cloud Trace operation with its input schema so the agent calls the right endpoint without browsing the reference docs.

FAQs

Specific to using Cloud Trace API through Jentic.

What authentication does the Cloud Trace API use?

It uses Google OAuth 2.0 with the https://www.googleapis.com/auth/trace.append scope for ingestion and https://www.googleapis.com/auth/cloud-platform for the broader read paths. Through Jentic the OAuth credentials are stored encrypted in your Jentic One instance and never reach the agent runtime.

Can I push OpenTelemetry spans to Cloud Trace?

Yes. Use the official OpenTelemetry exporter for Cloud Trace, or send spans directly to /v2/{name}/traces:batchWrite. The endpoint accepts a list of spans with their parent IDs, start time, end time, and attributes.

What are the rate limits for the Cloud Trace API?

Span ingestion is limited per project per minute and individual spans are capped in size. Batch your spans into the batchWrite endpoint instead of calling spans.create individually to stay well under the per-minute quota.

How do I send a trace span through Jentic?

Search Jentic for 'send trace span', load the traces.batchWrite schema, and execute the call against /v2/{name}/traces:batchWrite with a list of spans. Jentic returns the schema so the agent does not need to read the Cloud Trace discovery doc.

Is the Cloud Trace API free?

Cloud Trace gives a generous monthly free tier of trace spans per billing account and charges a small fee per million spans beyond that. The API itself has no per-call surcharge.

Can I limit what my agent is allowed to do with the Cloud Trace API?

Yes. Because Cloud Trace carries the project resource name in the URL path (/v2/{+name}/traces:batchWrite), your self-hosted Jentic One instance lets you pin your agent to a single project so it can write trace spans there and nowhere else. You decide which operations are exposed, so you can allow only the batch span-write call and withhold the single-span create endpoint, or the reverse. The OAuth credential stays with the operator and is injected at execution time, so the agent can call exactly the span-ingestion operations your rules permit and nothing more.
