Using treg, build me a lead list: 50 US software companies with 51 to 200 staff
that raised a Series A. For each one find the VP or Head of Marketing, find their
work email, verify it, and pull the latest news so I have an opener.
$1.00 of free credit on every new team. No provider signup, no credit card.
$3.62 for 50 companies (from a real run). Email finder from $0.0245/found, verification from $0.00625/call.

What happens when you run it
The agent finds the companies.catalog_search "search companies by size and funding" returns
eleven providers for that one job: and this is the sharpest price spread in the whole catalog:

Same job. A 200× spread, and the cheapest option is free. Coverage differs, which is exactly why the
price is not the only column: but nobody should pay $0.38 a record without knowing $0.0019 was on the
table.
It finds the people. Two routes, and the cheaper one is usually the right one. If you want everyone
at a company, hunter.companies.emails returns the known addresses at a domain in a single call,
100% success across 597 calls, 0.4 s median, the fastest endpoint in this whole workflow. If you want
one named person, hunter.people.email.find costs $0.0245 and only charges when it finds someone
(100% across 582 calls, 1.4 s). Enrichment fills thin profiles: Hunter $0.0245 (356 calls, 0.3 s),
Apollo $0.026 (263 calls, 0.3 s), LeadMagic $0.025, Coresignal $0.392.
It verifies before you send: and this is the step that matters most. Verification is the single
most-called enrichment endpoint on treg.to: 963 calls at 100% success. It runs at $0.00625 with
LeadMagic or $0.01225 with Hunter. Finding an address is cheap; sending to a dead one costs you a domain
reputation, which is why the teams already doing this at volume verify more than they search.

Evidence
Proof from one real run
Run on treg.to, 26 Aug 2026: the full 50-company workflow, one prompt, one key. Every figure is
from that run's receipt, published with its CSV at
/workflows/find-and-verify-a-lead-list.

Total metered
$3.62 for 50 companies, or $0.13 per deliverable lead
Where misses were free, and where they were not. Hunter and LeadMagic charge only on success,
so their misses settled at $0.00. Findymail and Tomba list a free miss too, but neither reports the
charge in its response, so treg.to settled their calls at the list rate, misses included: $0.56 of
the $3.62. The receipt is the real total, not the rate card.
The honest read of this run: 27 deliverable leads from 50 companies is one market on one day,
not a benchmark. The hit rate on your market is what the $1.00 free credit is for: run ten rows
first and read your own receipt before you commit to a list.
Outcomes
Three things you can do the day you sign up
Build a list for a campaign you have not committed to yet.
Test whether your ICP even exists at the size you assumed. Company search starts free, so you can check
the market before anyone signs a contract for the data.
Enrich the leads you already have, without a new seat.
Point the agent at your existing CSV of names and domains. It fills in titles, company size and verified
emails, and marks the rows it could not resolve rather than guessing.
Stop paying for bounces.
Verify every address before it enters the sequence. At $0.00625 a check, verifying a 2,000-row list costs
about $12.50: and Hunter's finder does not charge you for the ones it cannot find.
Fit
Who this is for
Founders doing their own outbound, who need 50 good contacts this week and cannot justify a seat.
SDR teams whose credits run out mid-month, and who want per-lookup pricing that matches actual usage.
Growth teams testing a new segment where they do not yet know which provider has coverage.
Developers building sales agents who want one HTTP surface across finders, verifiers and company data instead of four vendor SDKs.
Questions
Before you sign up
Why not just call the providers directly?
Because this workflow is not one provider. Finding companies, identifying people and verifying email are
three different products, and the vendor that is best at one is rarely best at the others: the table
above is 200× wide for a single job. Holding accounts with all of them to find out is the expensive way
to learn it. If you already pay for one, connect it and those calls route through your key, unmetered.
treg.to is closer to OpenRouter for agent tools than to a data vendor: one base URL, one token, many
providers behind it.
How are credentials handled?
The credential is injected on the server. Your agent makes the real upstream request through treg.to's
/call/ endpoint; treg.to adds the key and relays the provider's answer back verbatim. No provider key
is ever written to your machine, your repo or your agent's context. Every call is recorded and attributed
to the token that made it.
Can I choose a specific provider?
Yes. Every endpoint has an id, and calling it by id calls that provider. If you want the choice made once
for the whole team, treg org pin <capability> --provider <provider> refuses calls to any other provider
of that capability.
(Often the right call here. Coverage varies by region and company size far more than it
varies by price, so once you find the provider that covers your market, pin it.)
Can I use my existing provider key?
Yes, and it takes precedence. Register the key once and every call to that provider routes through it;
those calls are never metered against your treg.to balance. Your key always wins over treg.to's.
(If your team already pays for Apollo or Hunter, this is the first thing to do. Those calls stop costing
you anything on treg.to.)
What happens if a provider fails?
treg.to does not silently reroute you. That is deliberate: only you know which inputs you actually hold,
so treg.to relays your request rather than rewriting it. Failed calls are not billed. If a call
succeeded upstream but the answer was lost coming back, an Idempotency-Key returns the stored result
without paying twice.
How much does a call cost?
A found work email is $0.0245 with Hunter and a miss is free. Verification is $0.00625. Company search
ranges from free to $0.38 a record depending on provider. The exact price is shown before the call, and
treg.to adds no markup to what the provider charges. New teams start with $1.00 of free credit: enough
for roughly 40 verified email lookups before you spend anything.
Which agents does it work with?
The installer registers treg.to's MCP server into Claude Code, Cursor and opencode automatically. Any MCP
client that supports the authorization spec can connect with OAuth. Anything that can run a shell command,
Codex included, can use the treg CLI or plain HTTP.
How does this compare to Clay?
Clay is a visual table for GTM workflows. treg.to is a catalog of the same data providers Clay calls,
exposed as tools your agent can use directly. If you already think in prompts rather than spreadsheet
formulas, you skip the table and get the same waterfall enrichment in one paste. The providers are the
same (Apollo, Hunter, Clearbit, etc.); the interface is your agent. Clay is not in the treg.to catalog
because it is a workflow tool, not a data API.
Is there an Apollo MCP or Hunter MCP?
Yes. The treg.to MCP server gives your agent access to Apollo, Hunter and the other enrichment providers
through one connection. Install once, and every provider in the catalog answers to it. See /llms.txt
for the setup line.
