The prepaid balance your AI agent can spend.

One balance. All your API keys. Your agent discovers, calls, and pays — mid-conversation, with your keys vaulted once and governed in one place. When the balance runs out, the agent hands you a payment link and finishes the job after you top up.

Install

See it happen

Demo film incoming — an agent hits the paywall, presents the payment link, and finishes the job after top-up.

dataforseo and open-meteo are resold: no provider account or key from you — we are the customer; your agent calls apipay. Resold APIs are metered at the listed per-call price — the exact number in this table is what your balance is debited. Weather data by Open-Meteo.com (CC BY 4.0). Brave, ScrapingBee, OpenWeather (weather), and fal stay bring-your-own-key: your agent asks for a secure one-time vault link, you paste your existing provider key once, and from then on your agent uses it freely — your provider account pays the provider, apipay meters a flat 0.1 credits per call. Existing vaulted OpenWeather keys on weather are unchanged. 1 credit = $0.01 · packs: $5 → 500 credits, $20 → 2,000 credits · 500 free credits at signup. Want an API we don't route yet?
