Changelog and migration policy
v1.0 — July 28, 2026: stable public IDs, strict filters, pagination, conditional caching, rate-limit headers and snapshot exports.
The earlier multiprotocol preview remains temporarily available on its old specialist routes and with ?legacy=1 for list routes. New integrations should use the documented dataset response; legacy compatibility may be retired only after a published migration window.
Breaking changes require a new versioned path. Additive fields may appear in v1; integrations should ignore unknown fields. A deprecated major version will be documented before removal.
Acceptable use: cache results, avoid scraping HTML, do not use the service to conceal abuse, and report unwanted or incorrect endpoint listings through contact/takedown.
