OpenRouter
OpenRouter is an API platform that provides unified access to multiple AI language models through a single interface. OpenRouter acts as a "router" or gateway that lets developers and applications access dozens of different AI models from various providers through one standardized API, rather than having to integrate with each provider separately.
OpenRouter publishes 7 API contracts indexed on the APIs.io network, including Completions API, Credits API, Generation API, and 4 more. Tagged areas include Artificial Intelligence, Gateways, LLM, and Router.
The OpenRouter catalog on APIs.io includes 1 JSON-LD context and 1 Spectral governance ruleset.
OpenRouter’s developer surface includes authentication, getting-started guide, FAQ, pricing, developer portal, documentation, support, and 40 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 Model Routing | coverage | 50.0 | - | 2 |
| Agent Skills (SKILL.md packages) | coverage | 50.0 | - | 2 |
| Stripe App Marketplace and Partner Ecosystem (builders on Stripe) | coverage | 50.0 | - | 2 |
| GitHub Marketplace (GitHub-native publisher layer) | coverage | 50.0 | - | 2 |
| Raycast Store Extensions (first-party publishers + community-wrapped products) | coverage | 50.0 | - | 2 |
| Obsidian Community Plugins (third-party APIs the Obsidian plugin ecosystem integrates) | coverage | 50.0 | - | 2 |
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.
