Amazon influencer API: the influencers behind an ASIN, with proof.

Q: Is this Amazon's Creators API?

No. Amazon's Creators API serves Amazon's product catalog to Amazon Associates. Spreesy's API answers a different question: which influencers' videos, photos and idea lists feature a product, from Spreesy's own index of public storefronts.

Q: Which Amazon marketplaces does the API cover?

Amazon US (amazon.com). A request for another marketplace answers unsupported_marketplace; the API never switches marketplace on its own.

Q: Does a match mean the influencer was paid, or is on the product page?

No. A match means the influencer's content carries the exact ASIN. It does not show a paid partnership, a sale, the tone of a review or a place in the video row on Amazon's product page.

Q: Can I try the API before paying?

Only with the reference's examples, which are free and fictional. Live answers need the plan, and your first API charge is refunded in full if you ask within 30 days.

Q: What happens when my results run out?

Requests stop with quota_exceeded and your remaining balance. Buy 10,000 more for $39 on your API page and carry on at once, or wait for the next billing month. Nothing is charged automatically.

Q: Can I call the API from a browser?

No. Keep your key on your server. A key in a browser, an app or a URL can be copied by anyone who sees it.

Q: Do I need the seller plan as well?

No. The API is its own plan on your Spreesy account. The seller plan and Influencer Studio are separate, and neither includes the API.

Send an ASIN and get every indexed influencer whose videos, shoppable photos or idea lists feature that exact product, with the evidence for each match and the date it was observed.

For software that serves Amazon sellers, and for agencies that run influencer work for brands.

How it works

From signup to your first page of influencers.

Create your account
Then subscribe on your account's API page. No call or approval sits in between.
Create a key
It is shown once. Keep it on your server, never in a browser or an app.
Send an ASIN
Request its influencers with your key, and a new Idempotency-Key for each page you ask for.
Page through
Each page holds up to 50 influencers, 20 unless you ask for more. Follow next_cursor until it is null.

Each result

One influencer per result, with the evidence behind it.

A storefront appears once per ASIN, however many of its videos, photos and idea lists carry the product.

Field	What it gives you
`influencer`	The storefront: its ID, handle, name, photo, storefront link and the social links its Amazon page publishes.
`matching_content_counts`	How many indexed videos, photos and idea lists carry the exact ASIN.
`evidence`	Up to 5 of those items with their titles, links and thumbnails where Amazon has them, the newest of each kind first.
`coverage`	Whether Spreesy has read all, part or none of each kind of content on that storefront.

Only exact matches: never a variation or a similar product.

A match shows that an influencer's content carries the product. It does not show a paid partnership, a sale or a place on Amazon's product page, so the evidence and its dates travel with every result.

Dates and freshness

Answers come from the index, with the dates to judge them.

Answers are read from Spreesy's index of public Amazon storefronts, updated monthly, never from a live Amazon check, and every result says when it was observed.

Date	What it means
`relationship_observed_at`	When Spreesy saw this video, photo or idea list carrying the ASIN.
`coverage.checked_at`	When Spreesy last read that kind of content on the storefront.
`profile_checked_at`	When the storefront's name, photo and links were last read.
`meta.generated_at`	When this answer was built, not when anything was observed.

An ASIN no indexed influencer carries answers with no results and no_indexed_matches, free. That means none in the index, not none on Amazon. A temporary failure is an error you retry, never an empty answer.

Pricing

Renews monthly. Cancel anytime from your account.
Taxes added at checkout where applicable.

30-day money-back guaranteeAsk within 30 days for a full refund of your first API charge.

One result is one influencer returned, with all of its evidence.
Empty pages are free, and so is a retry with the same Idempotency-Key.
Asking about the same ASIN again is a new lookup, charged again.
Included results reset each billing month and do not carry over.
When your results run out, requests stop with your balance. Nothing is charged automatically.

Extra results when you need them

$39 for 10,000 results, bought on your API page at any time. They last 12 months and are used after your included results, while your plan is active. Unused ones can be refunded within 30 days of buying them.

Say your product shows 20 influencers for each ASIN a customer checks: the included results cover 1,250 of those checks a month.

In your product

Show the results to your own customers.

In your software and client work

Show results inside your own product and in reports and exports for your clients. No Spreesy branding is required.

Kept for up to 30 days

Store results for up to 30 days while you are subscribed, then ask again. Delete stored results when your access ends.

Removed when we ask

When an influencer's information has to be removed, we tell you and you remove it within 30 days. Reselling results as a dataset is not allowed.

The full rules are in the API terms.
