**JavaScript SDK:** [`swarmhit.leads.enrich(leadId, params?)`](/smart-api/sdk/methods#leads) Looks up the lead's work email (by default) and/or mobile phone now and returns the lead with what was found saved on it. A value the lead already has is kept, and not charged or looked up again. A hit usually answers in a couple of seconds; a miss only once every source was tried, which can take up to a minute. Charged per result found, at the Email finder or Phone finder price (Settings → Credits usage, for owners and admins); nothing for a miss. `enrichment.<kind>.status` says how each lookup ended. A lookup already running on this lead is a 409 with `code: lookup_running`.
