Locus

Locus gives AI agents a single account, a single balance and a catalog of paid APIs and data sources, so a developer does not have to open a separate provider account and manage a separate API key for every tool an agent calls. An agent discovers tools by the outcome it needs, such as web search, data enrichment, transcription or financial data, and Locus meters and bills each call from one prepaid balance. It serves individual developers building agents, platform companies embedding agent capabilities in their own products, and enterprises running many agents at once. The catalog spans OpenAI, Groq, DeepSeek, Gemini, ElevenLabs, Mapbox, CoinGecko and more than 30 other providers. Every plan includes unlimited agent connections, API and SDK access, catalog access and spend controls, and the enterprise tiers add per user balances and billing integration. Authentication is browser based, with no provider keys to store. Two products are published. Locus Pro is a subscription: Free at $0 per month with no included allowance and pay per use tools, Plus at $20 per month with $30 of included monthly usage, Enterprise at $200 per month with $30 of included usage, Enterprise Plus at $1,000 per month with $1,100 of included usage, and Enterprise Custom at negotiated pricing for larger commitments. Pay With Locus is a wallet product at $0 per month with no subscription or minimum: users fund a USDC wallet on the Base blockchain and pay per tool use at each provider's published price. Locus is part of the Y Combinator fall 2025 batch. The wallet product's reliance on USDC means a finance team should confirm it can hold and reconcile a stablecoin balance before choosing that route over the subscription.
