Orbis API Marketplace runs on your own machine — the client starts it, so there is no endpoint to ping. 51 installs a week from npm. Last commit 11 Jun 2026.
8,000+ pay-per-call APIs via x402 USDC micropayments on Base. No API keys needed.
Today is the operative word: we check Orbis API Marketplace every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
