botpay-facilitator.alexwlex143.workers.dev is a Cloudflare Workers–hosted facilitator that lets developers replenish API key quotas via on‑chain USDC payments on the Base network. It exposes a single endpoint (/api/api-keys/add-quota) to perform micropayment quota top-ups, making it suitable for automated billing, pay-per-use flows, and low-cost developer credit systems.
