Jungle Scout API: Who Gets It, What It Costs, the Six Endpoints and the MCP Server

Yes, Jungle Scout has a public, documented API, and its price is published. It is open to Growth Accelerator and Brand Owner subscribers: the first 100 requests are free, then 1,000 requests a month cost $29, 4,000 cost $99 and 10,000 cost $199, with $0.05 for each request over the limit. Jungle Scout’s MCP server is a separate Cobalt product (all read 11 November 2026).

Search results blur three things that Jungle Scout sells separately: the self-serve API, the API that Cobalt customers get under contract, and the MCP server for AI assistants. This page takes them in turn. The sources are Jungle Scout’s help-center API articles, the readme and source code of its official Python client on GitHub, and its MCP guides, all read on 11 November 2026. The FAQ answers on its API page are quoted from the Internet Archive’s copy of 5 October 2026; the rest of that page was read on 11 November 2026.

Does Jungle Scout have an API?

Yes. Jungle Scout hosts its developer documentation at developer.junglescout.com, publishes an official Python client and a Postman collection, and keeps a set of API articles in its help center. Who can use it depends on the plan:

Under its sign-up button the API page says “API available with Jungle Scout account”, which reads as any account. Its own FAQ is narrower: “Growth Accelerator or Brand Owner plans only”. The help center’s API access article (edited 22 January 2025) agrees, and adds that subscribers on the older Suite and Professional plans qualify too.

So the cheapest way in is Growth Accelerator, at $49 a month billed annually or $79 monthly (checked 10 October 2026). You can’t buy the API on its own. Our Jungle Scout pricing guide covers what else that plan includes.

Jungle Scout’s site footer calls this product the “Jungle Scout SMB API”. Cobalt customers reach the same six endpoints with a different header value, on terms set by their contract.

How to get a Jungle Scout API key

The steps in the API access article:

1. Open the Developer page inside Jungle Scout.
2. Click Generate Key at the top right.
3. Enter a key name, using only letters, numbers and underscores, and click Generate Key.
4. Copy the key and store it somewhere safe. The article warns: “Once exiting the API Key window, you will not be able to copy this key again.”
5. To go past the free requests, open Subscriptions, click Purchase API and choose a tier. Jungle Scout says “usage will begin immediately”.

The Developer page shows a usage meter. On Cobalt the steps are the same, but the Cobalt help center (edited 27 March 2025) notes that “Only Admin users can generate API keys.”

Jungle Scout API pricing

The pricing table’s “Additional API requests” row only says “Learn more”, which is probably why many pages call the price unpublished. Jungle Scout publishes it in two places, the API access article (read 11 November 2026) and the FAQ on the API page, and they agree:

What the two sources say about how the tiers work:

• The period is a month. The help article lists the tiers without one; the API page FAQ words them as “1,000 requests/month for $29.00”, and the page offers “custom API options” to anyone who needs “more than 10,000 API requests a month”.
• Unused requests expire. “Exceeding the API request limit will result in an overage charge as requests do not roll over.”
• The API bills on its own cycle. You cancel it under Subscriptions and keep access “until the end of your API Subscription period”, and “This billing cycle may be different from your Jungle Scout membership.”
• The trial looks like a one-off. Jungle Scout calls it the “first 100 requests”; nothing we read says it renews.

What a request buys. The FAQ says “Each page of an API response equals one request”, and a page holds up to 100 results. Its examples: a Product Database query with 2,000 results takes 20 requests, a Keywords by ASIN query with 500 results takes 5, and a whole year of sales estimates for one ASIN takes 1. By that arithmetic the 100 free requests cover a year of daily estimates for 100 ASINs, or 10,000 Product Database rows.

Watch the overage. At $0.05, an extra request costs 1.7 to 2.5 times the tier rate. Going 1,400 requests over the 1,000 tier costs $70, the same as the step up to the 4,000 tier (our arithmetic).

What data the API returns: six endpoints

The paths are from the source code of Jungle Scout’s Python client, and the limits from the help center’s endpoint descriptions (edited 18 July 2025):

Three details from the endpoint guides:

• Historical Search Volume has two stated limits. The overview’s table and the endpoint’s own guide give one year per call (“Maximum date range: 366 days”), while the overview’s detail section says “up to 2 years”.
• Sales estimates are per parent ASIN. For a variant, the endpoint “returns sales estimates for the parent ASIN as an aggregate of all variants”.
• Share of Voice isn’t in the self-serve app. Jungle Scout’s platform guide (edited 25 June 2026) marks Share of Voice “Not available” in Catalyst, the self-serve web app, so the endpoint appears to give self-serve subscribers data the app itself lacks.

Marketplaces, authentication and rate limits

Marketplaces. The help center’s Postman guide (edited 12 February 2025) says “All the Jungle Scout APIs will require the marketplace parameter”, and the endpoint guides list ten country codes: us, uk, de, in, ca, fr, it, es, mx and jp. A key may not cover all ten: the Cobalt help center’s API FAQs say “all API Keys attached to your account are also linked to a sub-set of supported country codes”. These are the same ten stores as Jungle Scout’s research tools; our Jungle Scout marketplaces guide shows what the other stores get.

Authentication. It works by API key, not OAuth. The Postman guide has each request carry four headers, sent to the base address https://developer.junglescout.com:

Authorization: KEY_NAME:API_KEY
X-API-Type: junglescout
Accept: application/vnd.junglescout.v1+json
Content-Type: application/vnd.api+json

The Python client’s source defines two API types, junglescout for the Jungle Scout API and cobalt for the Cobalt API. The Accept header carries the version, v1.

Rate limits. The Python client’s documentation says: “The Jungle Scout API enforces rate limits as following: 300 requests per minute or 15 requests per second. If you exceed the rate limit, you will receive a 429 status code”. The help center’s endpoint guides (edited 18 July 2025) repeat “300 requests/minute, 15/second”.

Jungle Scout’s own pages disagree here. The Cobalt help center’s API FAQs (edited 24 January 2024) say “Users can make up to 150 requests per minute”. The Python client’s rate-limit note (added in October 2024) and the 2025 endpoint guides are newer and both say 300, so 150 looks like the stale figure.

Tooling. Besides the Python client (pip install junglescout-client), the help center’s API resources article lists a Postman collection and Google Apps Scripts, and the API page links a Zapier integration.

Jungle Scout MCP: a Cobalt product, not part of the API plans

MCP (Model Context Protocol) lets an AI assistant query a data source directly. Jungle Scout has an MCP server, but it sits on the enterprise side of the company:

• What it is. The platform guide says “Jungle Scout MCP connects Cobalt’s Amazon marketplace intelligence to the AI tools your team already uses”.
• Which assistants. The guide names “Claude, ChatGPT, Gemini, Copilot, and approved custom or internal AI environments”. Jungle Scout’s getting-started guide has connection sections for Claude, ChatGPT, Gemini Enterprise Plus, Copilot Studio and Snowflake.
• How it connects. Jungle Scout’s ai-skills repository on GitHub ships “An MCP server configuration for Claude pointing to https://ai.junglescout.com/mcp”, and its setup steps include “Authenticate with Jungle Scout Cobalt credentials.” The same repository holds a Claude plugin named jungle-scout-cobalt and a skills file for ChatGPT.
• Who can have it. “MCP is powered by Cobalt’s Amazon intelligence, so access to Cobalt data is required.” The guide also calls it “available as a standalone offering powered by Cobalt’s data”, and in both cases the route is a demo or your customer success manager.
• What it costs. Jungle Scout publishes no price, and the self-serve pricing table has no MCP row.

That leaves a Growth Accelerator or Brand Owner subscriber with the API and no official connector. Unofficial ones exist: the npm package junglescout-mcp, published in June 2026, wraps the API for AI tools, and its readme calls it “Unofficial”. Our Jungle Scout Cobalt guide explains the enterprise platform, and our roundup of AI tools for Amazon sellers compares the connectors.

What the Jungle Scout API doesn’t provide

• Your own account data. The six endpoints return market data. None covers the sales, advertising or inventory analytics of a connected seller account, the Supplier Database, Rank Tracker or Review Automation.
• Anything outside Amazon, or outside ten stores. Australia, the UAE and the Netherlands, for example, aren’t among the country codes.
• Live data. The endpoint descriptions call most values “Current/last known”, and Share of Voice is “a point-in-time snapshot of search results based on the last scrape”. The Cobalt API FAQs say keyword data is “updated at least once a week” and sales estimates “bi-weekly”.
• Exact sales. The Sales Estimates guide says figures “should be used for directional insights rather than precise accounting purposes”. Our Jungle Scout Sales Estimator guide looks at how far to trust them.
• A free tier. The 100 requests come with a paid plan, and Starter gets none.

Jungle Scout API vs Helium 10, Keepa and Data Dive

The models differ as much as the prices:

• Helium 10 documents no general API: a search of its help center for “API” on 11 November 2026 returned 20 articles, none describing one. Its MCP guide (edited 4 November 2026, read 11 November 2026) says the connector needs the Diamond plan or higher, with 1,000 calls a month included and top-up packs of 500 more for $50. Our Helium 10 API page has the detail.
• Keepa limits speed, not volume: its API page (read 11 November 2026) prices plans by tokens a minute and says every plan includes every endpoint, all 11 marketplaces and the AI connector. Our Keepa pricing guide lists the tiers.
• Data Dive puts both on Standard and Enterprise: its help center (edited 22 October 2026) says “Starter plans do not include either feature”. Our Data Dive review covers what the API carries.

Jungle Scout is the only one of the four whose AI connector needs an enterprise contract. For a self-serve subscriber, its strength is the documented API.

Bottom line

• You want Jungle Scout data in a spreadsheet, dashboard or script: subscribe to Growth Accelerator, spend the 100 free requests on a test, then pick the tier that covers your monthly volume. Move up a tier before you run into overage.
• You want to ask an AI assistant questions about Jungle Scout data: the official MCP means a Cobalt demo. On a self-serve plan, the API and your own code are the only supported route.
• You need more than 10,000 requests a month: Jungle Scout sends you to sales.
• You are on Starter: there is no API access; our Jungle Scout review covers what that plan does include.
