Developer API · included in every plan
Every account, every metric and every action your team uses in SellerMate, available to the dashboards, reports, alerts and agents you build yourself. One key covers Amazon Ads, DSP, AMC, Seller Central and Vendor Central. No Amazon API approvals, no data plumbing.
Any workspace admin can create a key in under a minute. Read-only keys available.
Paste this into Claude, ChatGPT or Cursor
Read https://www.sellermate.ai/api-docs — it documents the SellerMate Public API (REST, API-key auth; every tool and its parameters are on that page). Help me build: [describe your tool — e.g. a weekly ACoS report per client, posted to Slack every Monday]. Call get_user_context first to list my Amazon accounts, then use the reporting tools. My key is in the SELLERMATE_API_KEY environment variable — send it as the X-API-Key header and never hard-code it.
Works because the docs page lists all 76 tools with their parameters in plain HTML, so your assistant reads it in one go. Prefer the raw spec? openapi.json.
What teams build
The hard part of an internal Amazon tool was never the UI. It was getting clean, current data for every account. That part is done.
A branded page per client with spend, sales, ACoS and what changed this week — no SellerMate login needed.
Ping the team the moment a campaign crosses an ACoS line or a hero product is about to run out.
Search terms, placements and SQP data landing daily in the sheet your team already lives in.
An assistant that reads live account data, proposes negatives and bid changes, and applies what your guardrails allow.
Budget, bid and state changes across every account in one run, policy-checked, up to 50 items a call.
Every account’s performance and orders into BigQuery or Snowflake for the BI you already run.
What’s in the API
The same engine behind the SellerMate app and its AI agent. Every tool is called the same way, POST /public/v1/tools/{name} with a JSON body, so your assistant only has to learn one pattern.
Find your workspaces, Amazon accounts, what SellerMate supports, and which report data has arrived.

R read tools cover analytics, reports and inventory. W write tools change campaigns, targets, negatives, automations and AMC audiences. A key can be limited to read only.
How it works
In SellerMate, open Profile → API Keys. Choose read-only or read-and-write, and optionally restrict it to specific Amazon accounts. The key is shown once, so store it as SELLERMATE_API_KEY.
Paste the prompt from the top of this page into Claude, ChatGPT, Cursor or whatever you build with, and describe the tool you want. The model reads /api-docs and writes the code.
Run it wherever you like: a Vercel app, a cron job, a Google Apps Script, a Zapier step. Every call is key-authenticated, permission-checked and logged.
The first call your assistant will make
1curl -s -X POST https://api.sellermate.ai/public/v1/tools/get_user_context \2 -H "X-API-Key: $SELLERMATE_API_KEY" -H "Content-Type: application/json" -d '{}'
It returns your workspace and every Amazon account the key can use. Everything else takes an amazon_account_id from that list.
Built for agencies
The API inherits the controls your admin already set in SellerMate, so handing it to a builder is not handing them the keys to every account.
Budget and bid limits, never-pause and never-archive lists, ACoS guards. A blocked write returns 422 and nothing reaches Amazon.
Limit a key to one client’s accounts, or to read only. Revoke it and it stops on the next call.
Every call is recorded against the key that made it, the same log your team sees for the app and the AI agent.
120 requests a minute per key, with a Retry-After header when you hit it. No per-call pricing to forecast.
No. SellerMate already holds the Amazon Ads, Seller Central and Vendor Central connections for every account in your workspace. You call SellerMate with one key and get all of them.
Nothing extra. It’s included in every SellerMate plan, with a default limit of 120 requests per minute per key.
Any workspace admin, from Profile → API Keys in the SellerMate app. Keys can be read-only, limited to specific Amazon accounts, and revoked at any time.
That’s who this is for. Copy the prompt at the top of this page into Claude, ChatGPT or Cursor and describe the tool you want. The documentation page is written so a model can read every tool and parameter in one fetch.
MCP connects your AI chat (Claude, ChatGPT) to your data for conversations. The API is for software you build and run yourself: dashboards, syncs, alerts, agents. Many teams use both.
Every write passes your workspace guardrails: budget and bid limits, never-pause and never-archive lists, ACoS guards. A write that clears them applies immediately; one that doesn’t returns 422 and nothing is sent to Amazon. Every call is audit-logged.
Yes. Sponsored Ads, Amazon DSP, Amazon Marketing Cloud audiences and reports, Seller Central retail and inventory data, and Vendor Central sales and inventory.
Create a key, paste the prompt, describe what you want. The API is included in every plan.
