Do I need a Lusha account?

For 18 platform tools, no. The other 13 require your own Lusha key. All 31 accept your own key, and treg never meters BYOK calls.

What does a call cost?

Each tool on this page shows its rate; the cheapest is $0.00499/result. The rate is the provider's own and treg.to adds no markup; it is billed per call from a prepaid balance. It is not Lusha's subscription pricing, which is on their own site. New teams start with $1.00 of free credit.

How do I add Lusha to Claude Code?

Run: claude mcp add --transport http treg https://treg.tracea.online/mcp. One MCP server carries Lusha and the rest of the catalog.

Which frameworks does it work with?

Anything that speaks MCP (Claude Code, Claude Desktop, ChatGPT, Codex, Cursor, Grok) and anything that can make an HTTP request (LangChain, CrewAI, LlamaIndex, plain code).

Is this the official Lusha MCP server?

No. treg.to serves Lusha's real API through its own metered proxy: the request is the provider's own, the credential is injected server-side, and the answer is relayed verbatim. The official Lusha channels are linked above.

Enrich a company by domain or name — headcount, funding · Platform + BYOK · live-verified · $0.25/success
Enrich a company from domain or name — industry, headcount, revenue, funding, tech lusha.companies.enrich
TWO credits per company record returned, not one. OBSERVED live 2026-07-31: one domain in, one result out, billing.creditsCharged 2. The rate card lists revealCompany at 1 per 1, so search-and-enrich evidently bills the search (companySearch) AND the reveal — which means the rate card UNDER-STATES this route by half, and the two-step path (prospecting, then POST /v3/companies/enrich on the ids you keep) is the cheaper one when you already hold ids. A no-match is free, as on the contact side.
Search companies by industry or tech (free preview) · Platform + BYOK · live-verified · $0.00499/result
Search Lusha's companies by industry, headcount, revenue or tech (free preview) lusha.companies.search
OBSERVED live 2026-07-28: billing.creditsCharged 1 for 1 result — 1 credit per up to 25 results (pricing.companySearch), not free as the docs prose claims. Re-confirmed 2026-07-31 against the live rate card (companySearch: {credits: 1, perQuantity: 25}), so a size=10 page and a size=25 page cost the same: page in 25s
Find lookalike companies from 5-100 seed companies · Platform + BYOK · live-verified · $0.125/result
AI-powered recommendations for companies of similar size, industry and profile to 5-100 seed companies lusha.x.companies-lookalike
OBSERVED live 2026-07-28: 1 credit for 1 returned result (lookalikeCompany, perQuantity 5 per account/usage pricing)
List company filter values · Platform + BYOK · helper · live-verified · free
Enumerate the accepted values for one company-prospecting filter type (industry, size, revenue, technologies, intent topics, etc.) lusha.x.companies-prospecting-filters
measured on our own account — called it twice and credits.used did not move (24 -> 24); only the request rate-limit counter advanced. Filter enumeration is metadata, not data
List accepted values for one company signal filter · Platform + BYOK · helper · live-verified · free
Returns the valid values for a specific company-signals filter type lusha.x.company-signal-filter-values
filter discovery endpoint; not billed
List the filter types available for company signals · Platform + BYOK · helper · live-verified · free
Returns the available filter types for company signals and their query requirements lusha.x.company-signal-filters
filter discovery endpoint; not billed
List supported company signal types · Platform + BYOK · helper · live-verified · free
Returns the list of supported company signal types (headcount changes, hiring surges, website traffic, IT spend, news categories) lusha.x.company-signal-types
type/filter discovery endpoint; not billed
Enrich companies by Lusha id (up to 100) · Platform + BYOK · $0.125/result
Enrich companies you already found in a prospecting search, by ids (max 100), into full firmographic records lusha.x.companies-enrich-by-id
billed on the reveal_company action per company returned; a no-match is free. Lusha does not publish the numeric credit cost — read GET /v3/account/usage.pricing for the calling plan's actual number.
Hiring and headcount signals for company ids · Platform + BYOK · $0.125/result
Retrieve signal events for a list of companies — hiring activity, headcount changes, web traffic, IT spend and news lusha.x.companies-signals
billed on the showSignalsCompany action per matched signal. Lusha does not publish the numeric credit cost — read GET /v3/account/usage.pricing for the calling plan's actual number.
Rank companies by website-visit signals · BYOK only · No treg charge; upstream own account
Returns companies ranked by website-visit signals for your tracked domains, combining firmographics with visit metrics (score, sessions, unique visitors, avg session length) lusha.x.companies-website-visits
NOT on our plan — the API answers "Website Visits is not available on your current plan", so there is no rate to record and treg cannot serve it on our key

People & contact data · 9 tools

Reveal emails and phone numbers for found contact ids · Platform + BYOK · live-verified · $0.125/result
Reveal emails and phone numbers for contacts you already found in a prospecting search lusha.people.contacts.enrich
billed per revealed datapoint across the batch, email and phone charged separately. OBSERVED live 2026-07-28: revealing the email of one id reported billing.creditsCharged 1. A PHONE COSTS FIVE TIMES THAT — the live rate card (GET /v3/account/usage.pricing) gives revealEmail 1 per 1 and revealPhone 5 per 1, re-read 2026-07-31, so `reveal: ["phones"]` on a 100-id batch is a 500-credit call. Unlike the search-and-enrich routes this one charges the reveal only, because the search was already paid for by the prospecting call.
Find a person's work email and phone by LinkedIn or name · Platform + BYOK · live-verified · $0.25/result
Enrich a person — work email, direct dial and mobile — from email, LinkedIn or name lusha.people.enrich
VERIFIED live 2026-08-13. The live rate card (GET /v3/account/usage.pricing) prices contactSearch at 1 credit per 25 results and revealEmail at 1 per 1, so a fresh single-contact email enrich = 1 search + 1 reveal = 2 credits — confirmed by a fresh match reporting billing.creditsCharged 2 (resultsReturned 1). A phone reveal is +5 (revealPhone 5 per 1), an email +1. A contact Lusha cannot match is free (billing.creditsCharged 0, re-observed 2026-08-13). CAVEAT: re-revealing a contact already revealed to this account recently is discounted (an immediate repeat charged 1, not 2); value 2 is the fresh/upper-bound cost.
Find a person's phone by LinkedIn URL, email or name · Platform + BYOK · live-verified · $0.749/success
Reveal a person's direct-dial or mobile from a LinkedIn URL, email, or name + company domain — Lusha's native phone data lusha.people.phone.find
The live rate card (GET /v3/account/usage.pricing, read 2026-09-04) prices contactSearch at 1 credit per 25 results and revealPhone at 5 per 1, so a found number = 1 + 5 = 6 credits — the reveal half confirmed live by a contacts/enrich reveal reporting billing.creditsCharged 5. A contact Lusha cannot match is free (creditsCharged 0, observed 2026-09-04); a matched contact with no number still costs the 1-credit search (creditsCharged 1, observed 2026-09-04 twice). Every response carries `billing.creditsCharged`, which is what treg settles on.
Search people by title, company or intent (free preview) · Platform + BYOK · live-verified · $0.00499/result
Search Lusha's contacts by title, seniority, company, location or intent (free preview) lusha.people.search
OBSERVED live 2026-07-28: billing.creditsCharged 1 for 10 results — 1 credit per up to 25 results (pricing.contactSearch), NOT free as the prose on this endpoint's docs page claims. Re-confirmed 2026-07-31 against the live rate card (contactSearch: {credits: 1, perQuantity: 25}). Verify against GET /v3/account/usage.pricing before trusting the docs text on any Lusha endpoint
List supported contact signal types · Platform + BYOK · helper · live-verified · free
Returns the list of supported contact signal types (promotion, companyChange, allSignals) lusha.x.contact-signal-types
type/filter discovery endpoint; not billed

AI-powered recommendations for contacts who share similar roles, seniority and company profile to 5-100 seed contacts lusha.x.contacts-lookalike
OBSERVED live 2026-07-28: 1 credit for 1 returned result (lookalikeContact, perQuantity 5 per account/usage pricing)
List contact filter values · Platform + BYOK · helper · live-verified · free
Enumerate the accepted values for one contact-prospecting filter type (job titles, seniority, departments, locations, etc.) lusha.x.contacts-prospecting-filters
measured on our own account — called it twice and credits.used did not move (24 -> 24); only the request rate-limit counter advanced. Filter enumeration is metadata, not data
Find the buying-committee contacts at a company · Platform + BYOK · $0.125/result
Resolve up to 25 companies to Lusha company ids, rank their buying committee (decision makers, champions, end users) with Lusha's persona model, and return lightweight contact previews grouped per company (1 credit per contact returned - always pass contactsLimit) lusha.x.buying-group
Lusha's OpenAPI bundle: "Charged per contact returned via the buyingGroupContact action". The same action was OBSERVED on the retired decision-makers path 2026-09-02 (billing.creditsCharged 44 for resultsReturned 44); this path has not been called by treg yet. treg settles from billing.creditsCharged, so the per_result estimate (contactsLimit) is the reservation only; the bill is the row count
Job-change and promotion signals for contact ids · Platform + BYOK · $0.125/result
Retrieve signal events for a list of contacts — job changes and promotions lusha.x.contacts-signals
billed on the showSignalsContact action per matched signal. Lusha does not publish the numeric credit cost — read GET /v3/account/usage.pricing for the calling plan's actual number.
