Raw lead objects to process. Field names are auto-mapped (e.g. company / organization / companyName all map to companyName). Combine with 'inputDatasetId' to merge sources.
ID of an existing dataset (e.g. the output of a scraper Actor) whose items are loaded as leads and merged with any inline records. This is the 'chain on top of your scrapers' input.
Override or extend the default field aliasing. Keys are source field names, values are one of: fullName, firstName, lastName, jobTitle, email, phone, linkedinUrl, companyName, website, country, city, source.
Merge duplicate leads (same email globally, or same company + fuzzy-matched name). Field values are merged with provenance tracking.
Jaro-Winkler similarity (0-1) above which two names within the same company are treated as the same person. Higher = stricter.
When a lead has a name + company domain but no email, generate ranked candidate addresses from common patterns (first.last@, flast@, etc.). Guessed emails are flagged isGuessed=true and never claimed as verified.
Validate syntax, check the domain's MX records (real DNS lookup), and flag disposable / role-based addresses. Mailbox-level (SMTP) verification requires a provider — see emailVerifierApiKey.
Optional. If set, enables mailbox-level verification via your provider hook in src/email.ts (e.g. ZeroBounce, NeverBounce). Leave empty to use free MX + heuristic verification only.
Resolve company-level attributes from the domain: industry classification, detected tech stack, and MX presence. Results are cached per domain so overlapping lists don't re-pay.
Allow firmographics to fetch the company homepage to infer industry and detect tech signals. Disable for a faster, network-free run that uses only DNS-level signals.
Optional. If set, enables your paid firmographics provider hook in src/firmographics.ts (e.g. People Data Labs, Clearbit) for headcount, revenue, etc. Leave empty to use free inference only.
Defines how each enriched lead is scored 0-100. Omit to skip scoring.
Emails or domains to drop entirely (compliance / opt-outs / competitors). Matching leads are excluded from the output.
[]Hard cap on input records after loading (0 = no limit). Useful for test runs.
Parallel enrichment workers. Keep modest when fetching homepages to be polite.
