There are 562 L402 services on satring.com but you have to pay 100 sats to see the list. We seeded the ones we could find publicly.

The article discusses L402, a Bitcoin Lightning-based authentication protocol for paid APIs, and highlights satring.com's directory of 562 services requiring a 100-sat payment for access.
