A great rep once knew every account. An agent doesn't, unless you tell it what's true and how sure to be.
Enrichment APIs hand your agent a value. An email. A job title. A funding round. The agent acts on it: writes the email, books the play, updates the CRM. But was that email verified, or guessed? Most APIs won't say. For a human scanning a spreadsheet, fine, you eyeball it. For an agent sending on your behalf, an unmarked guess is how it emails a made-up address with total confidence.
So we built abm.dev the other way round. Every field carries its own source and a confidence score. Not a blended trust rating for the record. Per field.
Eighty-nine canonical fields on an enrichment, forty-three on a person, forty-six on a company. Ten providers behind one call, LinkedIn, Companies House, Hunter, Perplexity, Tavily and five more, aggregated, deduped, reconciled. One key, one schema, no per-source bills. And every value comes back wrapped:
{
"work_email": {
"value": "jsmith@acme.com",
"confidence": 0.94,
"source": "hunter.io",
"verified": true
},
"employee_count": {
"value": 240,
"confidence": 0.61,
"source": "linkedin",
"note": "companies-house filing says 180; both kept"
}
}
When sources disagree, we don't silently pick a winner. We keep both and tell you. No fabricated data. No silent fallbacks.
That envelope is the whole point for an agent. It can gate on confidence: act on 0.94
, hold on 0.61
, route the low ones to a human. It can cite its own work, so when someone asks why did you email this person, there's a source, not a shrug. Grounding is the difference between an agent that builds pipeline and one that hallucinates it.
And the honest bit, because an agent needs the honest bit: it's near-useless on companies with no public footprint. The difference is it tells you when it's guessing, instead of guessing in a confident voice.
Three verbs sit on top of the same idea. Search the accounts and people. Enrich them into cited fields. Create the records and the outreach. Over a plain REST call, or as a Claude Connector your agent talks to directly over MCP.
If you're building anything that acts on B2B data without a human in the loop, come make it prove itself. There's a free playground at abm.dev, and LAUNCHCODES
puts about twenty in credits on your account to try it on an account you know cold. Tell me where it's wrong, that's the useful part.
