Cheapest company data enrichment API
Eight APIs—People Data Labs, Apollo, Parallel, Predict Leads, Explorium, CompanyEnrich, ZoomInfo, and Exa—receive the same company domain and enrich it by API calls from their official docs.
Most pricing comparisons list rate cards. This one lists measured cost for identical work: what the same 282-company enrichment run actually cost at each provider's public self-serve rate — shown next to measured accuracy, because the cheapest API that writes wrong data isn't cheap. Currently cheapest: CompanyEnrich at $2.76 for the cohort.
Which company enrichment API is best?
There isn't one best enrichment API. The right choice depends on what happens next: filling CRM records, avoiding bad overwrites, matching a prospect list, returning complete company profiles, or powering a latency-sensitive product flow. Choose the job below; each recommendation is based on the metric that matters for it.
Which provider wins depends on the use case — CRM writeback, prospecting and matching, complete company profiles, or real-time product flows. The workflows below are ranked separately for each.
| Workflow | Recommended API | Measured evidence |
|---|---|---|
| Best API for keeping CRM records current | People Data Labs | 89.0% enrichment success rate |
| Best API for safe CRM writeback | Apollo | 92.6% field accuracy |
| Best API for the most complete company data | Parallel | 94.7% field coverage |
| Best API for matching a company list | Predict Leads | 100.0% company match rate |
| Best API for real-time product or agent enrichment | People Data Labs | 274 ms median latency |

Compare provider results field by field.
This is the main benchmark's per-field table for HQ location, industry, employee band, founded year, and LinkedIn URL. Each value is correct-field yield among companies carrying a reviewed reference for that attribute, so denominators differ by column.

Enrichment cost — common questions
What is the cheapest company enrichment API?
At each provider's public entry self-serve rate, CompanyEnrich was the cheapest for the 282-company benchmark run ($2.76 total, at $0.0098 / credit). Free allowances, volume discounts, and minimum commitments are excluded; Apollo and Explorium use recorded usage proxies. The full cost-beside-accuracy table is on this page.
Is the cheapest enrichment API worth it?
Only if the data holds up — cheap wrong data costs more downstream than the credits saved. That's why cost is shown next to measured accuracy here: CompanyEnrich is cheapest at 69.7% correct field yield, while the yield leader is People Data Labs at 89.0%. Pick the cheapest option that clears your accuracy bar, not the cheapest outright.
How is enrichment API cost calculated here?
Recorded usage from the actual benchmark run multiplied by each provider's public per-unit rate on its entry paid self-serve tier (as of July 14, 2026), with each rate linked to the provider's pricing page. It's an estimate of like-for-like cost on identical work — not a quote; enterprise pricing and volume discounts will differ.
Is there a free company enrichment API?
Several providers offer free tiers or trial credits, but free-tier accuracy and limits aren't measured here — the benchmark ran on paid self-serve terms so every provider did identical work. Treat free-tier quality as a vendor claim until measured.
