Verid

Verid is an API-first website change monitoring platform that fires a webhook only when a specific value on a page crosses a predicate you define — not just when the page changes.

What is Verid?

Verid monitors any webpage for changes via a REST API. You provide a URL, an extraction method (CSS, XPath, JSONPath, regex, full-page hash, or AI extraction), and a predicate rule (e.g., “price dropped 10%”). Verid fetches the page, extracts the field you care about, compares it against the last successful run, and triggers a delivery (webhook, Slack, Discord, or email) only when your predicate returns true. The platform is built by Verid (est. 2026) and offers a permanent free plan with no credit card required.

Key Features

• Six extraction methods — CSS selectors, XPath, JSONPath, regex, full-page hashing, and AI extraction (LLM); output is always typed fields, never raw HTML.
• Predicate-based alerting — 9 predicate types (e.g., field changes, percent decrease, regex match) plus AND/OR composites; fires only when the rule you define triggers.
• Three-layer fetching — Static fetch first, auto‑fallback to a headless browser for JS-heavy pages, then residential proxies for bot‑protected sites.
• HMAC‑signed webhooks — Every delivery includes an X-Verid-Signature header; up to 6 automatic retries with exponential backoff, plus a dead‑letter queue for failed payloads.
• Multi‑channel delivery — Webhooks, Slack, Discord, and email; each carries the before/after diff of the changed field.
• Field‑level diff history — Every run stores the old and new value per field; see exactly what changed and when.
• REST API + Node SDK — Full OpenAPI 3.1 spec; create monitors in seconds with a single POST /v1/monitors call.

Who is it for?

• Developers — Monitor API contracts (e.g., GitHub, npm, PyPI releases) and get notified via signed webhook before CI breaks.
• E‑commerce teams — Track competitor pricing and inventory restocks using CSS extraction and price‑drop predicates.
• SEO / marketing teams — Watch Google SERP positions, AI Overviews, and featured snippets for specific keywords.
• Compliance officers — Monitor regulatory filing portals and government websites for new document posts using full‑page hashing.

What can you do with Verid?

• Competitive pricing: Extract the price from a competitor’s product page, fire a webhook when the price drops 5% or more.
• Inventory restocks: Use CSS selectors to watch “In Stock” status; trigger an alert when out‑of‑stock becomes available.
• Dependency releases: Poll GitHub, npm, or PyPI APIs with JSONPath; get notified immediately when a new version is published.
• API contract drift: Check an upstream JSON endpoint every 5 minutes; catch breaking schema changes before production does.

How does Verid work?

You create a monitor via API or dashboard: provide a URL, an extraction config (method + field mapping), a schedule interval, a predicate rule, and a delivery target. Verid runs the fetch–extract–diff–predicate–deliver pipeline on that interval. Extraction escalates from static fetch to headless browser to residential proxy if needed. Deliveries are HMAC‑signed and retried up to 6 times.

FAQ

Does Verid handle JavaScript‑rendered pages?

Yes. Static fetch runs first; if extraction returns empty fields, the job automatically retries with a headless browser. Bot‑protected sites fall through to a residential proxy.
