Three of the five repricers this site covers most often publish an Amazon repricer API you can read without talking to sales: Repricer.com, Informed and Aura. Seller Snap lists “API” as a plan feature but keeps its documentation behind a password. BQool publishes no developer documentation we could find. The three that do publish are not equivalent — one is a file-transfer API, one is a feed-and-report API, and one is a conventional REST API that writes individual listing fields. All findings below were checked on 2026-08-21 against each vendor’s own developer or pricing pages.
Which Amazon repricers publish a public API?
Checked 2026-08-21. “Public docs” means documentation readable without an account, a password or a sales call.
| Repricer | Public docs | Auth | What you can read | What you can write | Plan needed |
|---|---|---|---|---|---|
| Repricer.com | Yes — developers.repricer.com | HTTP Basic (api.repricer.com/v1) | Inventory and report files (CSV) | Min/max prices, repricing rules, costs — by uploading a file | Premium or Custom |
| Informed | Yes — developer.informedrepricer.com | x-api-key header | Reports and upload templates | Listing data, by submitting a feed | Any paid plan (no feature gates) |
| Aura | Yes — docs.goaura.com | API key via HTTP Basic or Bearer (api.goaura.com) | Listings, channels, repricing strategies | Per-listing cost, min, max, manual price, strategy, repricing on/off | Not stated on the pricing page |
| Seller Snap | No — docs.sellersnap.io is password-gated | Not published | Not published | Not published | Listed as included on all four plans |
| BQool | None found | — | — | — | — |
Two things stand out. First, “has an API” hides a large capability gap: Aura can flip repricing off for a single SKU with one request, while Repricer.com asks you to build and upload an Amazon-format file. Second, only one vendor of the five gates the API behind its top plans. If interface access is the reason you are switching tools, that gating is the number that matters, not the headline monthly price — the same logic behind the cost breakdowns in our Amazon repricing tools hub .
Repricer.com: a file-transfer API, gated to Premium
Repricer.com’s developer site documents two things: moving repricer files in and out of your account, and driving its report engine.
The file side is deliberately narrow. Its import guide states that imports are “a great method of quickly reviewing and updating your product information,” most commonly to “update Min Max prices and Repricing Rules,” and that they can also “set costs and read other data such as ASIN, Quantity, and Fulfillment Type.” The same page carries two limits worth designing around: “At the moment, only Amazon format files are available via the API,” and “It’s not recommended that files are uploaded more often than every 30 minutes.” The GET /repricers endpoint that returns an all-fields Amazon template also warns it “is not suitable when you have more than 25,000 SKUs,” pointing large catalogues at the reports flow instead.
The OpenAPI definition published on that page gives the mechanics: base URL https://api.repricer.com/v1, HTTP Basic authentication, CSV file responses. The reports side adds Submit Request, List Reports, Schedule Report and List report requests, and the parameter list enumerates roughly thirty report types by API value — PRICING_LITE, BUY_BOX_OWNERSHIP, NOT_BUY_BOX_OWNER, TOP_25_PRODUCTS_LOW_STOCK, PRODUCT_PROFITABILITY_ANALYSIS_30_DAYS and so on.
Access is tier-gated. On repricer.com/pricing (checked 2026-08-21), the “API integrations” row is marked not included for Core and Scale, and included for Premium and Custom. The same page’s FAQ says Premium “is for catalogues over 50,000 SKUs and businesses needing API access or net-margin repricing.” Repricer.com does not publish dollar prices on that page, so the real cost of API access there requires a quote — a pattern we cover in Repricer.com alternatives .
Informed: x-api-key, feeds in, reports out
Informed Repricer documents its API as two REST groups at developer.informedrepricer.com. Its own overview describes the API as “organized around REST” with “predictable, resource-oriented URLs,” returning JSON on all responses including errors.
Authentication is a single header. The docs state: “The x-api-key header is required on all authenticated API calls. To obtain your key, please visit the integrations page of your Informed Repricer account.” Rejected keys return a 401 carrying “Access denied, could not validate credentials: Unknown API Key,” and a lapsed account returns 401 with “Invalid account status” — useful because those two failure modes need different fixes on your side.
The split between the two groups is the practical part. The Reports API “can be used to request and download the reports available on the Reports page in the web app as well as the templates available on the Uploads page,” and Informed states it “supersedes the Export API and will eventually replace it fully.” The Listings Management API “can be used to submit feeds to update data in Informed Repricer,” and the two connect directly: “Files from the Reports API that contain user editable fields can be submitted as a feed using the Listings Management API.” All timestamps are UTC.
The reporting workflow is asynchronous by design: create a report request, get a request ID, poll for status, and download from the link the status response returns when the report completes. You can also list all report requests, which Informed notes covers reports requested through the web app too — a convenient audit trail if humans and scripts both touch the account.
On plan gating, Informed’s pricing page (checked 2026-08-21) leads with “Every repricing feature. One flat monthly price. No feature gates. No per-user fees,” and lists “Powerful API” among the key features rather than against a tier. That page showed Pro at $199/month and Launch at $99/month, with Launch described as pricing “until your business reaches $5,000 in monthly revenue.” Compare the rest of its feature set in Informed.co alternatives .
Aura: the only per-listing write API of the group
Aura’s documentation at docs.goaura.com is the most conventional developer experience here, and it is the one most often missed — general AI search answers in August 2026 still report being unable to find it.
Authentication: “All Aura API endpoints are authenticated using API keys,” managed at goaura.com/settings/developers, passed “via HTTP Basic Auth. Provide your API key as the basic auth username value. You do not need to provide a password.” Bearer authentication is offered as an alternative for cross-origin requests. All requests must be HTTPS. Rate limiting uses a sliding window with a documented default of 5 requests per second, which is the constraint that decides whether you sync a 50,000-SKU catalogue in minutes or hours.
The resources are listings, channels and repricing strategies, with list endpoints for each against api.goaura.com. The write path is Update a listing, and its parameters are the reason this API is different in kind from the other two: cost, minimum_price, maximum_price and manual_price (all integers in cents, with a required currency when any of them is sent), strategy (the ID of a repricing strategy to assign), and a boolean repricing — “the value true to enable repricing by Aura for this listing or the value false to disable repricing.”
That last flag is what most sellers actually want automation for: pausing repricing on a SKU when stock runs low, a promotion starts, or a supplier cost changes, without opening the dashboard. Aura documents manual_price as having no effect where repricing is off or a minimum price is unset, which is worth encoding in your own retry logic.
Aura’s pricing page (checked 2026-08-21) prices four annual tiers — Starter $37, Essential $77, Plus $157 and Pro $237 per month billed annually ($451, $931, $1,891 and $2,851 respectively) — gated by trailing monthly sales rather than features. The API does not appear as a row in that feature comparison at all; it is linked from the site footer under Product with a “New” badge. So the honest reading is: not documented as tier-gated, and not documented as included either. Confirm with Aura before buying a plan for API access. Where Aura’s tiers pinch on other dimensions is covered in Aura alternatives .
BQool and Seller Snap: what could not be verified
These two deserve a precise answer rather than an assumption in either direction.
BQool. No public developer documentation was found on 2026-08-21. The Repricing Central pricing page names integrations with InventoryLab and SellerAmp but does not mention an API or developer access. docs.bqool.com, developer.bqool.com and api.bqool.com returned no HTTP response at all from our client. BQool’s help centre is behind a bot challenge, but its indexed articles that mention “API” describe BQool calling Amazon’s API to fetch competitive pricing data — that is BQool consuming Amazon’s interface, not BQool exposing one to you. Absence of published docs is not proof that no API exists; it does mean you would be starting the conversation with support rather than reading a spec. BQool’s five plans run $25 to $300 per month, per marketplace (BQool alternatives
covers the rest).
Seller Snap. Its pricing page does list “API” as a feature row, and parsing the rendered comparison table on 2026-08-21 shows a check icon in all four plan columns — Starter, Accelerator, Standard and Unlimited. A documentation portal exists at docs.sellersnap.io, but it answers with “Enter the portal password to continue,” so nothing about scope, authentication or rate limits can be verified publicly. If the API is the reason you are considering it, ask for portal access before signing — the plan floor is $100/month billed annually, rising to $250 and $500 monthly at the middle tiers (Seller Snap review ).
Amazon’s own SP-API is not a repricer API
The search results for “amazon repricer api” are dominated by Amazon’s own Selling Partner API documentation, which answers a different question. Amazon’s Product Pricing API surfaces pricing and offer information — operations such as getPricing, getCompetitivePricing and getCompetitiveSummary return your listings’ prices and competing offers. Changing your own price is not part of that API; price writes go through the Listings Items API. (Amazon’s developer-docs pages returned a bot-protection challenge to our non-browser client on 2026-08-21, so this reflects Amazon’s published operation descriptions rather than a verbatim page read.)
The practical consequence: building directly on SP-API gives you data and the ability to set a price, but none of the repricing logic — no Buy Box strategy, no floor and ceiling enforcement, no rules engine, no competitor exclusion. That is the layer you pay a repricer for. A repricer’s own API is how you feed that layer: push costs from your accounting system, set floors from your purchasing data, pause SKUs from your inventory system. If you are still deciding what those rules should be, start with Amazon repricing strategies .
How to read “API” on a repricer pricing page
Four questions turn a feature-table checkmark into something you can scope.
Read or write? A reports-only API tells you what happened; it cannot change a price or a floor. Repricer.com and Informed both write, but through file and feed submission. Aura writes individual fields on individual listings. If your goal is “when my cost changes in the ERP, the floor changes in the repricer,” the difference is days of engineering.
What granularity? File-based writes mean the smallest unit of work is a file. Per-listing endpoints mean the smallest unit is one SKU. For a nightly full-catalogue sync, files are fine and often faster. For event-driven updates — a purchase order lands, one SKU’s cost moves — per-listing endpoints are the difference between a one-line call and a rebuild-and-upload job.
What frequency? Repricer.com advises against uploading more often than every 30 minutes. Aura documents 5 requests per second by default. Informed’s reporting is asynchronous, so your effective rate is bounded by report generation time, not by a request counter. Each implies a different architecture.
Which plan, and at what price? Only Repricer.com clearly gates the API by tier here, and it does not publish the price of the tier that unlocks it. Informed explicitly does not gate features. Aura and Seller Snap do not document the answer well enough to rely on — ask in writing before you buy.
Choosing by the job you want to automate
If you want to push costs and floors from another system on a schedule, all three documented APIs work. Informed is the least friction, since no plan upgrade is involved and the report-then-feed loop uses the same file shape both ways.
If you want event-driven, per-SKU control — pause this listing, change this floor, switch this strategy, right now — Aura is the only one of the five that documents endpoints at that granularity today.
If you are already on Repricer.com at Premium or Custom, the API is capable enough for scheduled operations, and the report catalogue is unusually broad. If you are on Core or Scale, budget for the upgrade, not just the integration.
If you are evaluating BQool or Seller Snap primarily for automation, get the documentation in hand before committing. Neither publishes enough for you to estimate the work.
FAQ
Does every Amazon repricer have an API? No. Of the five compared here on 2026-08-21, three publish developer documentation (Repricer.com, Informed, Aura), one lists an API on its pricing page without public documentation (Seller Snap), and one has no developer documentation we could find (BQool).
Can I change prices through a repricer’s API? Through all three documented APIs, yes, but by different routes. Repricer.com and Informed accept file or feed submissions that carry min/max prices and rules. Aura exposes a per-listing update endpoint that accepts minimum, maximum and manual prices directly.
Do I need a top-tier plan for API access? Only at Repricer.com among these five: its pricing page marks API integrations as included on Premium and Custom, not on Core or Scale. Informed states it has no feature gates. Aura and Seller Snap do not document tier requirements clearly.
Should I build on Amazon’s SP-API instead? Only if you intend to build the repricing logic yourself. SP-API gives you pricing and offer data plus the ability to set prices via the Listings Items API, but no strategies, floors or Buy Box logic — that is what a repricer supplies.
