When an AI is asked about your product, where does the answer come from?
AI agents increasingly answer supplement questions from structured databases rather than your website. Suplementor serves agents a normalized, verified view of your formulations through a payable API. Claim your brand and make sure that view is accurate.

Agents query structured data. Make sure yours is accurate.
- Suplementor serves a normalized, verified view of supplement formulations through a pay-per-call API (x402 protocol, USDC on Base). Agents that query our API receive structured ingredient lists with canonical substance IDs, normalized quantities, and — for brand-verified products — a verified badge in the response.
- The catalog is discoverable via llms.txt and /.well-known/x402.json — standard surfaces that agents check when entering a domain. Any agent that follows those surfaces can query the supplement catalog without prior knowledge of the service.
- If your formulation data in the catalog is outdated, incomplete, or normalized incorrectly, that is what any agent querying our API will see. Claiming your brand gives you control over the authoritative version of your product data in this channel.
How brand verification in the agent API works.
Claim your brand listings
Create a brand account and claim your products in the Suplementor catalog. Your products appear in agent API responses with a verified brand badge once claimed and reviewed.
Correct normalized data
Review the normalized ingredient list for each SKU. Submit corrections for outdated formulations, misread units, or discontinued products. Corrections go through the moderation pipeline — verified, not merely accepted.
Agent API discoverability
The Suplementor agent API is discoverable via llms.txt and /.well-known/x402.json — standard surfaces that AI agents check when entering a domain. Agents that follow discovery find the catalog and query it.
Brand analytics
See how often your products appear in agent API responses — which queries surface them and in what context.
Frequently asked questions
Do AI assistants use Suplementor data to answer supplement questions?
AI agents can query the Suplementor catalog through our payable API — discoverable via llms.txt and /.well-known/x402.json. Agents that discover and query our API receive normalized, verified formulation data. We serve whoever calls the API; we do not have contracts with specific AI platforms and do not claim that any particular AI assistant uses our data by default. What we can say: the catalog is structured for machine consumption, discoverable through standard agent discovery surfaces, and designed to be cited.
Can I control what the Suplementor API says about my products?
Yes, through the moderation pipeline. Brand accounts can submit corrections to normalized product data — ingredient names, doses, forms, and other label values. Corrections are reviewed and verified by our moderation team before they appear in the catalog and API responses. You can flag outdated formulations, discontinued SKUs, and misread label data. You cannot write arbitrary copy to the catalog — corrections must be traceable to label evidence, which is the basis of the verified badge.
What is the verified brand badge in agent API responses?
The verified brand badge is a field in the API response that indicates the product has been claimed by its brand and its normalized data has been reviewed. Agents that receive this signal can distinguish between product data from the general normalization pipeline and data that has been explicitly confirmed by the brand. It is designed to be a trust signal in agent-to-agent and agent-to-user contexts.
What is llms.txt and how does it relate to my brand?
llms.txt is a file at the root of a website (following the proposed llms.txt standard) that describes a service in plain text for AI agents. Suplementor's llms.txt at /llms.txt describes the catalog, the API endpoints, payment model, and discovery surfaces. AI agents that check this file can find the supplement API without prior knowledge of the service. Brands that claim their listings benefit from this discoverability because their verified data is in the catalog that the file describes.
