Verid
Verid is a developer-first web change detection API for monitoring any webpage for changes through structured data, not screenshots. Instead of alerting when a page visually changes, Verid extracts the exact field you care about, such as price, version, stock status, API response value, or availability, then fires a webhook only when a predicate you define is true. It is built for state monitoring, not screenshot diffing, giving developers structured extraction, durable state, field-level diffing, and predicate-driven delivery in one loop. Every monitor runs on a schedule you set through a full REST API with an OpenAPI 3.1 spec, so teams write the configuration while Verid runs the infrastructure. The pipeline follows five stages; fetch, extract, diff, predicate, and deliver. Verid starts with static fetch, automatically falls back to a headless browser when needed, and can escalate to a residential proxy when a site is harder to access.
