For Agents
Read live eBay API quota usage - calls remaining, window length, and reset time - for any eBay REST or Trading API resource. Two endpoints.
Use for: Get my application's remaining call quota for the Browse API, Check whether the Sell Inventory API quota is about to reset, List all eBay API resources and their current call limits for my keyset, Retrieve user-level rate limits for the authenticated eBay seller
Not supported: Does not handle business analytics, sales reporting, or traffic metrics - use for reading API rate-limit and quota status only.
The eBay Developer Analytics API exposes the call-limit and quota state of every eBay REST API and the legacy Trading API for a given application or user. Two endpoints - /rate_limit and /user_rate_limit - return per-resource quotas, calls remaining, time until window reset, and the length of the rolling window itself. Applications use it to throttle their own request rate before eBay rejects calls, and to alert engineering when a quota is about to run out. /rate_limit reports application-level limits and accepts a Client_Credentials access token; /user_rate_limit reports per-user limits and requires a User token from the authorization-code grant.
Install Jentic One Beta
Connect the Developer Analytics API to your agent
Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the Developer Analytics 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.
1
Step 1: Jentic One Host machine
# On the machine that will host your Jentic One instance:
curl -fsSL "https://jentic.com/install.sh?src=apis&api=%2Fapis%2Febay.com%2Fdeveloper-analytics" | sh2
Step 2: Agent machine
# On the machine where your agent runs (keep this separate from the instance):
curl -fsSL "https://jentic.com/install.sh?src=apis&api=%2Fapis%2Febay.com%2Fdeveloper-analytics" | 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 Developer Analytics API.
Fetch application-level remaining-call counts for every eBay REST resource via /rate_limit
Fetch per-user remaining-call counts for user-context endpoints via /user_rate_limit
Read the rolling-window length and reset timestamp for any eBay API quota
Drive client-side throttling before hitting eBay's hard rate-limit wall
Trigger pager alerts when an application's daily quota for a resource drops below a threshold
Compare quota burn across multiple eBay APIs (Browse, Inventory, Fulfillment, etc.) from one endpoint
Use Cases
Patterns agents use Developer Analytics API for, with concrete tasks.
★ Pre-flight quota check before a bulk job
Before launching a bulk catalogue refresh against the Browse or Item Feed APIs, an integration calls /rate_limit and inspects the remaining quota for the relevant resource. If fewer calls remain than the job needs, the integration delays until the next reset window rather than failing partway through with HTTP 429 responses.
Call /rate_limit, find the entry where api='buy' and resource='browse', and abort the job if remaining < 10000
User-level quota dashboard for a multi-tenant app
Multi-tenant SaaS tools that act on behalf of many eBay sellers call /user_rate_limit per connected seller to render a per-tenant dashboard of remaining calls. This catches the case where one seller's heavy use exhausts their user-level quota even though the application-level quota is healthy.
For each connected seller, call /user_rate_limit with their User token and persist the rate-limit array to the tenant_usage table
Alerting on quota exhaustion
Operations teams pipe /rate_limit responses into their monitoring stack (Datadog, Prometheus) on a 5-minute schedule. Alerts fire when remaining drops below 10% of the window allowance, so engineers can pause non-essential workloads before customer-facing flows start hitting 429s.
Every 5 minutes call /rate_limit, emit a metric per (API, resource) pair, and alert when remaining/limit < 0.1
AI agent integration via Jentic
An AI agent that orchestrates several eBay APIs queries Jentic with 'check eBay API quota' and Jentic returns the /rate_limit operation. The agent loads its schema and executes the call before scheduling a long-running task - when remaining quota is low for a target resource, the agent re-plans or defers the task until after the window reset, avoiding mid-run failures.
Use Jentic to search 'check eBay API quota', load /rate_limit, and execute it; if remaining for buy.browse < 100, defer the planned bulk lookup
Key Endpoints
2 endpoints — the ebay developer analytics api exposes the call-limit and quota state of every ebay rest api and the legacy trading api for a given application or user.

What agents get from Jentic-routed access to this vendor.
Setup
Wiring the eBay Developer Analytics API by hand means implementing eBay's OAuth 2.0 flow, choosing between the application client-credentials token and the user authorization-code token for each call, and pointing requests at the api.ebay.com developer/analytics host. Through Jentic you install once, import the Developer Analytics API from the API Directory, store the eBay OAuth credentials once, and your agent calls it.
Permission scoping
This API exposes two flat read endpoints, /rate_limit and /user_rate_limit, with no resource id in the URL path, so scope it by operation: you limit the agent to the operations it needs, such as reading application-level or user-level rate-limit status. Both are read-only quota checks, so the agent reports usage and nothing more.
Credential isolation
Your eBay OAuth application and user credentials are stored once, encrypted, by your own Jentic One instance and injected at execution time. They never enter the agent's prompt, logs, or context.
Intent-based discovery
Agents search Jentic by intent such as 'check eBay API quota', and Jentic returns the matching /rate_limit or /user_rate_limit operation with its input schema so the agent picks the application-level or user-level endpoint without browsing the reference docs.

FAQs
Specific to using Developer Analytics API through Jentic.
What authentication does the Developer Analytics API use?
/rate_limit accepts an OAuth 2.0 Application access token issued via the Client_Credentials grant. /user_rate_limit requires a User access token issued via the Authorization Code grant - the user must complete an eBay OAuth consent flow first. Through Jentic, both credential types live in your Jentic One instance and the agent receives only the scoped access token it needs.
Can I see legacy Trading API call limits with the Developer Analytics API?
Yes. /rate_limit reports quotas for both the RESTful APIs (Browse, Inventory, Fulfillment, etc.) and the legacy Trading API in the same response - each entry carries an API and resource pair, so the Trading API appears alongside the REST ones.
What are the rate limits for the Developer Analytics API itself?
Developer Analytics calls themselves consume quota under the developer.analytics resource. The defaults are generous - the API is meant to be polled - but you can confirm your specific allotment by calling /rate_limit and inspecting the developer.analytics entry in its own response.
How do I check my remaining quota through Jentic?
Search Jentic for 'check eBay API quota', load the /rate_limit operation schema, and execute it. The response is an array of resource entries, each with limit, remaining, reset, and timeWindow. Install with pip install jentic. Get started with Jentic One, the self-hosted execution layer.
What is the difference between /rate_limit and /user_rate_limit?
/rate_limit reports application-keyset-level quotas - the cap eBay enforces across all calls made with your Client_ID. /user_rate_limit reports per-user quotas - the additional cap enforced when one specific eBay user's token is used to call user-context endpoints. A heavy single user can exhaust /user_rate_limit while /rate_limit remains healthy.
Can I limit what my agent is allowed to do with the eBay Analytics API?
Yes. Because you run Jentic One yourself, your own rules decide which of this API's two operations the agent may call and which stored eBay OAuth credentials it may use. This API exposes only two flat read endpoints, /rate_limit for application-level quota and /user_rate_limit for per-user quota, so you scope the agent by operation, granting just the rate-limit check it needs. Both operations are read-only quota lookups, so a scoped agent can report remaining calls and reset windows and nothing more.
