APIs.io is a federated, agent-friendly API discovery network. It indexes API providers from across the public internet — their APIs, specifications, schemas, and collections.
The catalog holds 38,134 security artifacts, of which 22,629 are domain-security probes — a live read of TLS, HSTS, DNSSEC, SPF, and DMARC across every host and registrable domain a provider publishes. That is 26,073 domains and 35,457 hosts actually fetched, not asserted. apis.io/2026/08/05/d...
