"Has Anyone Successfully Used the ZoomInfo API for B2B Data Enrichment?"
Hey folks,
I’ve been testing out the ZoomInfo API to clean up and enrich our B2B contact lists, but I’m hitting some snags. The data’s great when it works, but I’m curious—has anyone here actually got it running smoothly for enrichment?
Like, are there specific endpoints you’re using more than others? Or any tricks to handle missing fields?
Also, how’s the match rate for you? We’re getting some hits, but it’s not as consistent as I’d hoped. Maybe I’m structuring the queries wrong?
Any tips or war stories would be clutch. Thanks in advance!

Yeah, we’ve been using the zoominfo api for a while now. The `/contacts/enrich` endpoint is solid, but you gotta make sure your input data is clean first.
We ran our lists through a dedupe tool (like Dedupe.io) before hitting the API, and the match rate jumped from like 60% to 85%. Also, their support docs are kinda hidden, but there’s a section on fuzzy matching—helps a ton with typos in names/companies.
Still, it’s not perfect. Sometimes you gotta fall back to Clearbit or Apollo if ZoomInfo misses.
Honestly, the zoominfo api is hit or miss for us. The company enrichment works better than contacts, IMO.
We mostly use `/companies/enrich` because it’s way more consistent. For contacts, we had to tweak the query params a lot—like adding job title filters and industry codes.
If you’re stuck, try their sandbox first. Saved us a bunch of failed API calls.
Pro tip: batch your requests. The zoominfo api throttles like crazy if you spam single calls. We wrote a Python script to chunk our CSV into batches of 100 and it runs way smoother now.
Also, their match rate sucks for smaller companies. If you’re targeting SMBs, maybe try Lusha or Hunter.io as a backup.
We gave up on zoominfo api for enrichment and switched to Seamless.AI.
Not saying ZoomInfo’s bad, but the pricing was nuts for our use case. Seamless lets you do real-time lookups without burning credits, which was a game-changer for our sales team.
Just my 2 cents.
Match rate issues? Same.
Turns out the zoominfo api works better if you feed it more fields. We started passing in domains + LinkedIn URLs (when we had ‘em) and the accuracy went up.
Also, their support team is lowkey helpful if you bug them enough.
Yo, we built a hybrid pipeline with zoominfo api and Clearbit.
ZoomInfo for firmographics, Clearbit for email verification. Works like a charm but yeah, it’s $$$.
If you’re on a budget, maybe try scraping LinkedIn Sales Navigator first?
The zoominfo api docs are a maze, but the `/search/contacts` endpoint is gold if you structure your queries right.
We use a combo of company domain + job title + location. Skip the fuzzy matching unless you’re desperate—it adds latency.
PS: Their API playground is clutch for testing.
We had the same struggles.
Ended up using zoominfo api just for company data and used Hunter.io for emails. The combo works, but it’s not seamless.
Also, their rate limits are brutal. Monitor your usage or you’ll hit a wall mid-campaign.
Thanks for all the insights, everyone!
Took your advice and tried batching our requests—way better. Also, the fuzzy matching tip was a lifesaver. Still not 100% on match rates, but it’s improved.
Gonna test Clearbit as a fallback like some of you suggested. Anyone got a referral code? Lol.
Also, +1 on the API playground. Why is that not the first thing they show you?!
