Obol runs on your own machine — the client starts it, so there is no endpoint to ping. 30 installs a week from npm. Last commit 1 Aug 2026.
Find, pay for & call APIs in USDC from AI agents - gasless, sub-cent, 0% commission.
Today is the operative word: we check Obol every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.

This one needs environment variables set before it will start:
OBOL_API_KEY (Your Obol API key (obl_sk_live_...) from obol-arc.web.app/settings — identifies your account for listing services and metered calls.), OBOL_AGENT_KEY (32-byte hex Arc wallet private key that signs gasless x402/EIP-3009 payment authorizations. Needed only for paying (pay_and_call); discovery and listing work without it.).
The author declared them in the registry entry; get the values from the project itself.
