Vendors will join this index through one free application and owner review. Sponsorship and affiliate links are optional additions to a listed record. Paying for a tier does not improve rank, scores or badges.
Three tiers
Listed vendors appear in the organic table under the same rules. Sponsorship, affiliate links and who built the site have no effect on ranking.
Listed (free). Your products come from your feed or a catalog URL you permit and appear as organic rows. Listing costs nothing and does not raise your position, scores or badges.
Sponsored (paid, under a signed contract). A placement module above the organic table, on the compound pages named in the contract and on your profile. It always carries this label: "Sponsored · Paid placement · does not affect ranking or scores." It does not change your organic rows, rank or scores.
Affiliate (optional, disclosed). You supply a link template and code. A disclosure sits next to each outbound button that uses them. Commission has zero ranking weight.
How to apply
One path. Nothing is approved automatically.
Application. You submit the form.
Owner review. The owner approves, declines with a reason, or asks for more information.
Verification. You verify your domain with a business email at that domain or a DNS TXT record.
Source registry. The owner records your source and decides whether it may be read.
Feed or catalog read. A feed or a catalog URL you permit is the normal path. Crawling is the exception.
Organic rows. Your listings appear under the same rules as other listed vendors.
Application fields
The form asks for company and contact details at your domain, testing and labs used, compounds sold, a feed or catalog URL, optional affiliate details, sponsorship interest (never approved automatically), an accuracy attestation and agreement to the listing terms.
Claiming an existing listing
Once claims open, you will be able to claim your company's listing: find it, verify by business-domain email or DNS TXT record, then manage your profile and feed. Claiming gives no control over rank, scores, badges, status or other parties' observations. After a claim you will see listing status, feed sync health, clicks and a corrections inbox.
How we read your data
We read only sources the owner clears in the source registry. We store the raw response as a snapshot before any parse, do not alter it, and keep it for 30 days; the prices read from it, with the snapshot's time and hash, are kept permanently. A value we cannot confirm is not shown, and never guessed.
Hard stops: a login wall, a CAPTCHA, a robots disallow, repeated 403 responses, or a cease-and-desist.
We never rotate IP addresses and never solve CAPTCHAs.
Evidence badges
Any evidence badge will be earned from documents, such as certificates of analysis. No tier, fee or commission will grant one.
Responses, disputes and corrections
You will be able to respond to your record and dispute any observation in it. You cannot edit or delete another party's observation. Disputes will be handled as cases, each recording the claim, evidence, status, decision and reason, and corrections will leave an audit trail. To report an error or dispute a record, use the contact address on the About page.
Scope
The index covers research-use-only materials and publishes no dosing, protocols or health claims.
