SellerSprite prices its API as per-endpoint subscriptions from $99 to $3,999 a month. You buy by email, not through a checkout page. SellerSprite does not advertise a free API tier. The only trial is a $99 Competitor Research pass: 6,000 requests inside 7 days.
The MCP side matters more for most readers in 2026. SellerSprite runs a 44-tool MCP server that pipes its Amazon data into about a dozen AI clients.
- Price range: $99 (Product Category) to $3,999 (Category Insights) per endpoint, monthly.
- How you buy: email fiona@sellersprite.com; the English site has no API checkout.
- Trial: the $99 Competitor Research weekly pass, 6,000 requests, 7 days.
- MCP server: 44 tools, SSE streaming, secret-key auth, 10 Amazon marketplaces.
- Docs: open.sellersprite.com loads Chinese-first; the MCP still works in English clients.
How SellerSprite Sells API Access
SellerSprite sells its API by direct email, not through a checkout page. Each endpoint is a standalone monthly subscription, priced from $99 to $3,999. You request a quote from fiona@sellersprite.com, the address behind the Contact API Team button. The open platform at open.sellersprite.com hosts the docs and console.
I opened the API section expecting a normal checkout. Instead, SellerSprite, also searched as Seller Sprite, prints every price and quota publicly, then routes every purchase through one inbox. Even the open platform's own pricing page hides behind a login.
Here is the buying path:
- Shortlist endpoints from the menu below and estimate your monthly request volume.
- Send that list to the API team address; the Contact API Team button on the pricing page opens it.
- Ask about the $99 Competitor Research weekly trial if you want proof of data quality first.
- Log in at open.sellersprite.com for the docs and the developer console.
SellerSprite API Pricing: The Full Endpoint Menu
The menu below lists all 21 endpoint subscriptions plus the $99 weekly trial, priced in USD. Each quota is a monthly request cap. The spread is wide. ASIN Details costs about $3 per 1,000 requests. Category Insights runs about $100 per 1,000.
The API services menu on SellerSprite's pricing page: each endpoint is its own subscription from $99 to $3,999 a month, and purchases are handled by email.
Competitor and Product Data Endpoints
Seven rows cover competitor and product data. ASIN Details is the volume pick: $149 a month for 50,000 requests. Only Google Trends carries a deeper quota. Related Products Lookup is the priciest here at $1,199 a month. The $99 Competitor Research weekly trial sits in this group too.
Endpoint | Monthly price | Requests per month |
|---|---|---|
Competitor Research (Weekly Trial) | $99 for 7 days | 6,000 within 7 days |
Competitor Research | $499 | 20,000 |
Product Research | $599 | 20,000 |
ASIN Details | $149 | 50,000 |
ASIN Sales Estimator | $799 | 40,000 |
BSR Sales Estimator | $449 | 40,000 |

Keyword Data Endpoints
Keyword data spans six endpoints. Reverse ASIN is the flagship at $999 a month for 40,000 lookups. Keyword Mining follows at $899. The two $499 rows split monthly keyword research from weekly ABA opportunity data. Google Trends is the budget row: $199 a month buys 100,000 requests, the largest quota SellerSprite sells.
Endpoint | Monthly price | Requests per month |
|---|---|---|
Keyword Mining | $899 | 40,000 |
Reverse ASIN | $999 | 40,000 |
Keyword Research (Monthly Data) | $499 | 40,000 |

Keyword Distribution | $699 | 40,000 |
Google Trends | $199 | 100,000 |
Category and Market Data Endpoints
Nine rows span category reports and market statistics. The range inside this group is extreme. Product Category costs $99 a month. Category Insights costs $3,999 for the same 40,000-request quota, about 40 times more. Five market endpoints price identically at $499.
Endpoint | Monthly price | Requests per month |
|---|---|---|
Product Category | $99 | 40,000 |
Category Insights | $3,999 | 40,000 |

What the SellerSprite API Data Covers
The endpoints map to SellerSprite's core research datasets: sales estimates, keyword traffic, and category analytics. The web app covers 9 Amazon marketplaces (US, UK, DE, FR, IT, ES, JP, IN, CA). The MCP server page lists 10. SellerSprite says it serves 1.7M+ registered sellers.
API rows are abstract until you see the screens behind them. My hands-on SellerSprite review walks those screens tool by tool. The platform holds a 4.1 in my full review.
- Sales estimates: ASIN Sales Estimator models unit sales per product; BSR Sales Estimator models them from rank alone.
- Keyword traffic: Reverse ASIN returns the search terms behind any listing; Keyword Mining expands seed terms into long-tail lists.
- ABA data: the ABA Opportunity Finder endpoint builds on Amazon Brand Analytics weekly search data.
- Market structure: concentration, seller type and location, shelf trends, and ratings feed category-level market reports.
SellerSprite says its product research database holds 20M+ records. Treat every estimate as directional and sanity-check a few ASINs you know before scaling up.
The SellerSprite MCP Server
SellerSprite runs an MCP server at open.sellersprite.com/mcp with 44 tools; the hero banner rounds down to 40+. It streams over SSE, authenticates with a secret key, and covers 10 Amazon marketplaces. SellerSprite pitches setup as 5 minutes to connect with 0 lines of code.
MCP (Model Context Protocol) is the standard AI assistants use to call outside data tools. Once connected, your assistant queries live Amazon numbers mid-conversation. SellerSprite publishes client setup guides for Claude Desktop, Codex, ChatGPT on the web, Chatbox, CherryStudio, and Coze. Roughly six more clients get their own guides.
The MCP page lists 44 tools and SSE setup guides; the open-platform docs load Chinese-first, but the server runs in English clients like Claude Desktop.
The tool list reads like the web app split into atoms:
- Product and competitor tools: asin_detail, asin_sales_trend, asin_prediction, bsr_prediction, product_research, and competitor_lookup.
- Keyword tools: keyword_miner, keyword_research, keyword_research_trends, plus traffic_keyword, which pulls a competitor's traffic words from its top three pages over the last 30 days. traffic_extend runs the same pull across multiple ASINs.
- History and ABA tools: keepa_info covers price, BSR, and review history; aba_research_weekly, aba_research_monthly, and aba_research_trend cover Amazon Brand Analytics terms.
- Market tools: market_research, market_brand_concentration, traffic_source, traffic_listing_stat, and review.
One caution before you plan around it: the MCP is tied to SellerSprite's API side rather than the $39 a month seller plans. Budget for the API path, not the web app path.
What a Prompt-Driven Session Looks Like
A connected client turns endpoint calls into plain questions. You type a request in Claude Desktop and the assistant picks one of the 44 tools. SellerSprite streams the answer back over SSE. asin_detail reads listing stats, keyword_miner expands seed terms, and keepa_info returns price and BSR history.
Operator scenario: Say you manage 40 ASINs and want a Monday briefing. You ask Claude to run asin_sales_trend on your top 10 and keepa_info on 5 rivals. Then aba_research_weekly checks 3 seed terms. One prompt chain replaces about an hour of tab-hopping. Every number lands in one chat thread.
How SellerSprite's API Model Compares
SellerSprite is the only tool of the four below that prices data per endpoint. Keepa sells tokens on a subscription from €29 a month. Helium 10 gates its MCP behind the $279 a month Diamond plan, billed yearly. Jungle Scout ships its MCP on its enterprise side.
Provider | Where API or MCP access lives | Entry point |
|---|---|---|
SellerSprite | Per-endpoint API subscriptions plus MCP | $99 a month endpoint |
Keepa | Token subscription, one bucket for all calls | €29 a month |
Helium 10 | MCP bundled into Diamond and up | $279 a month billed yearly |
Jungle Scout | MCP on its enterprise side | Enterprise plans only |
The Keepa question comes up most. Keepa's specialty is price and BSR history; SellerSprite's menu leans on sales estimates, keywords, and ABA terms. If history charts are the whole job, tokens cost far less than any endpoint here. I ran that math in the Keepa API pricing guide.
The MCP angle flips for existing Helium 10 customers. Diamond subscribers already get an MCP inside their $279 a month bill. Everyone else faces a platform upgrade just to reach it. SellerSprite lets you skip the platform entirely and pay for the data alone.
Who Should Buy SellerSprite API Access
The API targets teams that consume Amazon data programmatically: aggregators, agencies, SaaS builders, and AI workflow tinkerers. One $499 endpoint costs more each month than the Basic annual plan costs per year ($390). Regular sellers should start with the web app and skip the API until volume demands it.
- Buy an endpoint if: you feed dashboards, repricers, or product pipelines that burn thousands of requests a month.
- Connect the MCP if: you research inside Claude or ChatGPT and want live Amazon numbers without integration code.
- Stay on the web app if: you sell and just need research screens. Plans run $39 to $189 a month, and the SellerSprite pricing breakdown compares all four tiers.
Unsure whether SellerSprite's numbers fit your niche at all? The SellerSprite free trial guide shows how to test the full web app for 3 days without a credit card. Prove the data first, then talk endpoints.
The Verdict on SellerSprite's API
SellerSprite's API is real, priced publicly, and reachable from $99 a month. That mix is rare in Amazon data. The email purchase path and Chinese-first docs add friction. The 44-tool MCP server is the standout. It feeds AI clients Amazon data without a $279 a month platform bill.
- Get it if: you need programmatic sales estimates, keyword data, or ABA terms and can commit to per-endpoint subscriptions.
- Skip it if: you cannot plan monthly request volume yet. Start with the $99 weekly trial or the web app instead.
