Woofun AI reports that Orthogonal has closed a $4.3 million seed funding round led by Pantera Capital, with participation from Y Combinator, Pioneer, Decasonic, Blast Club, and Outbound Capital. The startup positions itself as a unified gateway enabling AI agents to discover, invoke, and pay for APIs, explicitly aiming to replicate the dominance of Alipay within the artificial intelligence sector.

The platform's architecture relies on three distinct operational pillars designed to solve specific friction points for autonomous software. Its discovery engine functions as a searchable marketplace where agents articulate requirements in natural language, triggering an automatic matching process with relevant services. Orchestration capabilities then manage the complex sequencing and logic required when multiple API calls must execute in tandem to complete a task.

A critical innovation addresses the identity and credit gap inherent to non-human actors. Since AI agents lack traditional identities or credit cards, Orthogonal allows them to purchase platform credits to settle transactions with various API providers. This payment layer supports both traditional fiat currencies and emerging protocols such as x402, ensuring broad compatibility across different financial rails.

Woofun AI data shows the platform currently supports over 35 APIs, with a strategic roadmap to expand this inventory to thousands within the next 12 months. Early validation for the project comes from Y Combinator-affiliated companies including Precip, Riveter, and Andi, which have already integrated or supported the initiative. The founding team brings significant institutional experience, with Christian Pickett, former head of payments at Coinbase, and Bera Sogut, a former Google engineer, co-leading the venture.

Notably, Orthogonal has not yet issued any tokens, signaling a focus on utility and infrastructure before potential tokenization. This approach mirrors the early growth trajectories of major fintech platforms that prioritized transaction volume over speculative assets. The successful capital raise underscores a growing market demand for standardized financial interfaces capable of supporting the next generation of autonomous AI workflows.
