Orthogonal
Orthogonal is a unified API and payment layer for AI agents, backed by Pantera Capital and Y Combinator. An agent describes what it needs in natural language and Orthogonal returns the right service from a catalog of 40+ third-party APIs (web search, data enrichment, scraping, email finding/verification, identity), then proxies the call and meters a per-call price. Access is available through a REST API (api.orthogonal.com), a TypeScript SDK (@orth/sdk), a Python SDK (orth), a CLI (@orth/cli), and an official hosted MCP server (mcp.orthogonal.com) for Claude, Cursor, and other agents. Billing is prepaid credits or pay-per-call stablecoin micropayments over x402 (USDC on Base) and MPP (USDC.e on Tempo). Orthogonal also publishes an open library of 88 installable Agent Skills.
Orthogonal publishes 61 API contracts indexed on the APIs.io network, including Account API, Discovery API, Run API, and 58 more. Tagged areas include Company, AI Agents, API Discovery, API Marketplace, and Agentic Payments.
The Orthogonal catalog on APIs.io includes 1 Spectral governance ruleset.
Orthogonal’s developer surface includes documentation, API reference, getting-started guide, pricing, signup flow, CLI, authentication, and 32 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) | standard | 58.1 | - | 3 |
| Agent Skills (SKILL.md packages) | standard | 58.1 | - | 3 |
| Stablecoins and Tokenization (stablecoin issuers, tokenized assets) | standard | 58.1 | - | 3 |
| x402 Micropayments & Agentic Pay-per-Call | standard | 58.1 | - | 3 |
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.
Standards implemented 6
Standards this provider implements or carries. De facto ones are profiled and measured by the API Commons; formal ones come from the standards directory and are linked by the provider's own tags. The evidence column says how each claim was established — not that it was made.
