Phos Labs
Phos Labs is an independent studio that sells behavioral-science "commerce intelligence" to AI agents: diagnose where a funnel loses customers, redesign a checkout, rewrite offer copy, optimize price framing and detect cognitive biases. The surface is a Bearer-key REST API at phoslabs.io/api/v1 (OpenAPI 3.0.3, 7 operations, an anonymous tool-and-price listing) and a hosted MCP server at mcp.phoslabs.io behind OAuth 2.1 with RFC 8414 / RFC 9728 discovery and dynamic client registration, listed twice in the official MCP registry and described by an A2A-shaped agent card with nine skills. Billing is prepaid credits (1 credit = EUR 0.01) debited per call, with x402 USDC micropayments stated but not verifiable. The same domain also hosts Mind of Granite, a consumer decision-guidance product.
Phos Labs publishes 8 API contracts indexed on the APIs.io network, including Audit API, Copy API, Detect Biases API, and 5 more. Tagged areas include Company, Behavioral Science, Conversion Optimization, E-Commerce, and Pricing.
Phos Labs’ developer surface includes documentation, API reference, getting-started guide, pricing, support, authentication, and 28 more developer resources.

Kin Score
Markets this provider is in provisional
The Kin Score Market layer reads a provider inside its market: its position, and how deep its integrations go. Depth is only comparable within a position. Provisional and unweighted: not part of the Kin Score or agent readiness.
| Market | Position | Depth | Registered MCP server | Declares compatibility |
|---|---|---|---|---|
| AI Agents (A2A agent cards) | undeclared | - | 1 | 1 |
Registered MCP server and declares compatibility are report only — not weighted. Undeclared means we found nothing we can read, so there is no number: we never infer integrations.
