# Buyary > Honest, evidence-based product verdicts: every product is scored across multiple independent lenses and backed by cited sources — the product "Evidence Layer", not a review blog or affiliate-driven opinion. Buyary evaluates products against multiple independent criteria, grounds each verdict in cited sources, and publishes transparent multi-lens scores — so shoppers, and the AI assistants they ask, get trustworthy, defensible recommendations. Every review page exposes its overall score, the lenses behind it, and the sources cited.

Corrections are reviewed within 30 days. - Founded by Christian Shelton (CEO), Piotr Jurczenko (CTO), Janelle Tiulentino (Design Engineering), and Taylor Zavattero (Content & Operations). ## How Buyary works - [Methodology](https://buyary.com/methodology): How products are scored across multiple independent lenses, with cited evidence. - [Editorial policy](https://buyary.com/editorial-policy): The independence and sourcing standards behind every verdict. - [About Buyary](https://buyary.com/about): What Buyary is and why the product Evidence Layer exists. ## For shoppers and partners - [For shoppers](https://buyary.com/shoppers): How to use Buyary's scores and cited sources to decide what to buy. - [For retailers](https://buyary.com/retailers): How Buyary works with retailers and brands. - [Contact](https://buyary.com/contact): Get in touch with the Buyary team. ## Developer platform The same evaluations published on buyary.com, served to agents and platforms over remote MCP or plain REST — same bearer keys, byte-identical responses. - [Introduction](https://buyary.com/docs/): What the Buyary Evidence Layer is and how it fits an agent stack. - [Quickstart](https://buyary.com/docs/quickstart/): Key to first call in under five minutes, over MCP or REST. - [Authentication & keys](https://buyary.com/docs/authentication/): The bearer model: one-time key reveal, revocation, and 401 semantics. - [MCP](https://buyary.com/docs/protocols/mcp/): The agent-native transport: server URL, per-client config, tool discovery. - [REST API](https://buyary.com/docs/protocols/rest/): The same service over plain HTTP: two endpoints, same keys. - [Data model](https://buyary.com/docs/data-model/): Field-by-field tables for every response object. - [Errors & limits](https://buyary.com/docs/errors/): Auth errors, the limited-coverage contract, and key lifecycle semantics. - [Playground](https://buyary.com/platform/playground/): Try both tools against a catalog snapshot, no key required. - [OpenAPI schema](https://buyary.com/openapi.json): OpenAPI 3.1 spec for the REST endpoints. - [Verticals](https://buyary.com/verticals/): Industry-by-industry coverage of the evidence layer — consumer electronics, automotive, pet care, and eight more. - [Request access](https://buyary.com/request-access/): Tell us what you'd build.
