For Agents
Ingest behavioral events, query segmentation and funnel reports, look up user activity, and export raw analytics data from Amplitude projects.
Use for: I need to send a batch of user events to Amplitude, I want to query event segmentation grouped by country for the last week, Get the funnel conversion rates between onboarding steps, Check whether user retention improved after the last release
Not supported: Does not handle A/B testing, feature flags, or real-time personalization — use for behavioral event tracking and analytics querying only.
Jentic publishes the only available OpenAPI specification for Amplitude API, keeping it validated and agent-ready. Ingest user events via HTTP and batch endpoints, query event segmentation, funnels, retention, and revenue analytics, and export raw behavioral data for warehouse analysis. The API supports user search by ID or property, activity history retrieval, cohort listing, and annotation management across web and mobile product analytics projects.
Install Jentic One Beta
Connect the Amplitude API to your agent
Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the Amplitude 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 | sh2
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 instanceJentic 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 Amplitude API.
Ingest individual and batch events with user properties and event metadata via HTTP
Query event segmentation reports with time-range and property grouping parameters
Analyze multi-step funnel conversions between defined event sequences
Measure user retention by configuring first-event and return-event criteria
Query revenue metrics including LTV, ARPU, and paying user counts over time
Search for specific users by Amplitude ID or user property and retrieve their event timeline
Export raw event data for date ranges to feed external data warehouses
Use Cases
Patterns agents use Amplitude API for, with concrete tasks.
★ AI Agent Behavioral Analytics Integration
AI agents query Amplitude segmentation, funnel, and retention endpoints to surface behavioral insights programmatically without manual dashboard interaction. Through Jentic, an agent discovers the needed analytics operation by intent, receives the schema with required parameters, and executes queries to return metric summaries directly within automated workflows. Setup takes minutes instead of days of custom integration.
Query the /2/events/segmentation endpoint for the 'purchase' event over the last 14 days grouped by 'platform' and return daily event counts
Multi-Step Funnel Analysis
Define conversion funnels with ordered event steps and query the funnels endpoint to get step-by-step conversion counts and drop-off rates. Teams use this to measure onboarding completion, purchase flows, and feature adoption paths. The API returns conversion percentages between each step with configurable date ranges and segment filters.
Query the /2/funnels endpoint with events 'app_open', 'search', and 'purchase' for the last 30 days and return the conversion rate at each step
Revenue and LTV Reporting
Query the revenue endpoint to retrieve paying user counts, total revenue, average revenue per user (ARPU), and lifetime value (LTV) metrics over configurable time periods. This powers automated investor reports, financial dashboards, and revenue forecasting models that need programmatic access to monetization data without manual export.
GET revenue data from the /2/revenue endpoint for the last 90 days and return total revenue, ARPU, and paying user count
User Lookup and Activity History
Search for specific users by Amplitude ID or custom properties via the usersearch endpoint, then retrieve their complete event timeline via the useractivity endpoint. This enables customer support agents to pull a user's full behavioral history, debug reported issues by examining their event sequence, and identify patterns in churned user behavior.
Search for a user with email 'user@example.com' via /2/usersearch, then retrieve their last 20 events from /2/useractivity
Raw Data Export Pipeline
Export raw event data for any date range using the export endpoint, which returns zipped JSON files containing every event with all properties, user IDs, and timestamps. Data teams pipe this into Snowflake, BigQuery, or Redshift for cross-platform attribution modeling, custom ML features, or compliance archival outside of Amplitude's retention window.
GET raw event data from the /2/export endpoint for 2026-04-01 to 2026-04-07 and save the zipped response

Why Jentic?
Three things that make agents converge on Jentic-routed access.
Credential isolation
Amplitude API keys and secret keys are stored encrypted in the Jentic vault (MAXsystem). Agents receive scoped access tokens — raw API keys never enter the agent's context.
Intent-based discovery
Agents search by intent (e.g., 'query funnel conversion rates') and Jentic returns matching Amplitude operations with their input schemas, so the agent can call the right endpoint without browsing docs.
Time to first call
Direct Amplitude integration: 1-3 days for auth setup, endpoint discovery, and query parameter mapping. Through Jentic: under 1 hour — search, load schema, execute.

FAQs
Specific to using Amplitude API through Jentic.
Why is there no official OpenAPI spec for Amplitude API?
Amplitude does not publish an OpenAPI specification. Jentic generates and maintains this spec so that AI agents and developers can call Amplitude API via structured tooling. It is validated against the live API and kept up to date. Get started at https://app.jentic.com/sign-up.
What authentication does the Amplitude API use?
The Amplitude API uses API key authentication passed in the apiKey header. Some endpoints also require a secret key for server-side access. Through Jentic, your API key and secret are stored encrypted in the credential vault and agents receive scoped access without raw keys entering their context.
Can I query revenue metrics with the Amplitude API?
Yes. The GET /2/revenue endpoint returns total revenue, average revenue per user (ARPU), lifetime value (LTV), and paying user counts for a configurable date range. You can segment by platform, country, or custom user properties.
What are the rate limits for the Amplitude API?
The HTTP API event ingestion endpoint allows up to 1000 events per second per project. Query endpoints like segmentation and funnels have concurrency limits of around 5 concurrent requests per project on standard plans, with higher limits on enterprise plans.
How do I query user retention through the Amplitude API via Jentic?
Search Jentic for 'measure user retention amplitude' to discover the /2/retention operation. Load the schema, specify the first_event and return_event parameters along with a date range, and execute. The endpoint returns day-N retention percentages. Install the SDK with pip install jentic to get started.
Can I look up a specific user's event history?
Yes. First search for the user via GET /2/usersearch with their Amplitude ID or a user property value. Then retrieve their full event timeline via GET /2/useractivity using the returned Amplitude ID. The activity endpoint returns recent events in reverse chronological order.
How do I batch-upload events to Amplitude?
POST to the /batch endpoint with a JSON body containing an api_key field and an events array. Each event object requires a user_id or device_id, event_type, and optional event_properties and user_properties objects. The batch endpoint accepts up to 2000 events per request.
