API questions

Is there an API for auditing Amazon listings?

Yes. POST an ASIN and marketplace to /api/v1/audit with your API key and you get the audit back as JSON: the score, category scores, ranked recommendations and anything that couldn't be verified. It's on the Agency plan.

Can I use it with Claude?

Yes. Add the Amazon SEO Ranking connector in Claude, sign in, and Claude can audit listings, check copy against Amazon's limits, look up keyword volume and ideas, and run a keyword gap. It's on Pro and Agency.

Does the API return rewritten copy?

No. The API and the connector return audits and keyword data. Rewrites are on the site and in Bulk Optimization.

What are the rate limits?

20 requests a minute and 300 an hour, per account. Each new audit uses one from your monthly allowance; listing your past audits doesn't.

How many API keys can I create?

Up to 10 per account, each one revocable.
