Enrichment API
by AlphaAxe
Ten company, person and email enrichment endpoints behind one API key
EnrichmentAPI is a credit-metered REST service that returns fresh company, person and email data on demand. Ten endpoints — company and person enrichment, funding history, reverse email lookup, email finder and verification, employee finder, company-to-domain, image-to-person and post enrichment — sit behind a single key, aimed at developers and revenue-operations teams filling CRM records or powering in-product enrichment without building a data pipeline.
EnrichmentAPI, operated by AlphaAxe and founded by Darshan Khandelwal with co-founder Manthan Koolwal and COO Akshat Khandelwal, is a REST data-enrichment service that exposes ten endpoints behind a single API key: Person Enrichment, Company Enrichment, Company Funding, Reverse Email Lookup, Company to Domain, Email Verification, Email Finder, Employee Finder, Image to Person and Post Enrichment, plus an Account API for usage reporting. Requests authenticate with an api_key query parameter and return JSON. A company lookup accepts a company identifier, domain or name and returns roughly forty fields including industry, company type, employee headcount band, founding date, location, founders and executives, revenue range, LinkedIn URL, recent posts with engagement metrics and a list of similar companies; the vendor's own documented example response completes in 631ms. Endpoints are priced in credits rather than calls — Employee Finder costs 0.1 credits, Company to Domain and Email Verification 1, Company Enrichment, Email Finder, Reverse Email Lookup, Image to Person and Post Enrichment 2 each, Person Enrichment 5, and the Funding API 10 — so effective per-record cost varies by endpoint as well as by plan tier. Requests are retried automatically for up to sixty seconds, and only HTTP 200 responses consume credits, with 408 timeouts and other errors refunded. The service sits at the small, self-serve end of a market dominated by People Data Labs, Clearbit, Apollo and ZoomInfo, competing on published per-credit pricing and breadth of endpoints rather than on audited coverage — it publishes no match-rate figures and appears in none of the major third-party enrichment benchmarks.
A RevOps or growth engineer who needs company and contact fields filled in a CRM or signup flow and wants a published per-credit price instead of an annual ZoomInfo contract.
Ten enrichment endpoints behind one key with credit costs published per endpoint, so the cost of an enrichment job is calculable before a line of code is written.

Key Features
- ✓Ten enrichment endpoints, one key
Company, person, funding, email finder and verify, employee finder and image-to-person share one credential and JSON contract.
- ✓Per-endpoint credit pricing
Every endpoint publishes a credit cost from 0.1 to 10, so job cost can be modelled before integration.
- ✓Company enrichment with ~40 fields
Returns industry, headcount band, founders, executives, revenue range, LinkedIn URL, recent posts and similar companies.
- ✓Failure-free billing
Only HTTP 200 responses consume credits; 408 timeouts and other error responses are refunded automatically.
- ✓Reverse email lookup
Resolves an unknown email address to a person record and current employer in real time for inbound qualification.
- ✓Company Funding API
Returns funding history for a company, feeding lead scoring, investor research and competitive monitoring workflows.
Capabilities
Use Cases
- •Signup form autofill
Resolve a work email domain to company size, industry and location so the signup form can stay short.
- •CRM hygiene sweep
Batch-enrich stale account records to restore headcount, industry and location fields before a campaign launches.
- •Funding-signal lead scoring
Pull recent funding rounds for target accounts and route newly funded companies to sales first.
- •Outbound list hygiene
Find and verify work email addresses before a send so bounce rate stays inside deliverability limits.
- •Employee mapping for account planning
Enumerate employees at a target account at 0.1 credits each to build an org map cheaply.
Ideal For
Best For
- ✓Filling firmographic gaps on inbound signups in real time from an email domain
- ✓Batch-enriching CRM company records with industry, headcount band, location and revenue range
- ✓Reverse email lookup to resolve an unknown address to a person and their current employer
- ✓Finding and verifying work email addresses before an outbound send
- ✓Pulling company funding history into lead scoring or competitive research
Not Ideal For
- ✗Latency-critical synchronous request paths — the vendor documents automatic retries of up to sixty seconds, and an independent review measured 408 timeouts on roughly 1-2% of requests
- ✗Enterprises that require an audited match rate or coverage guarantee; the vendor publishes none and the API is absent from the major third-party enrichment benchmarks
- ✗Regulated buyers with a strict compliance floor — there is no SOC 2, no SSO, no data residency and no self-hosted option, only a published GDPR policy and a DPA
- ✗Teams with a conservative posture on LinkedIn-derived data, since the company response carries LinkedIn URLs and recent LinkedIn posts and Proxycurl wound down in 2025 after LinkedIn sued it
Deployment
Market Analysis
Pros
- ✓Published, granular pricing: a per-endpoint credit table plus five self-serve tiers, where most competitors quote annually
- ✓Unusual breadth for the price — funding history, employee finder and post enrichment are normally separate products or separate vendors
- ✓Errors and timeouts are not billed, so a flaky batch job does not silently burn budget
- ✓A competing vendor's own comparison called the documentation candid where competitors are vague, and every plan unlocks every endpoint
Cons
- ✗An independent review by Nubela (Proxycurl) reports 408 timeouts on roughly 1-2% of requests and documented retries of up to sixty seconds, so callers must engineer around failure rather than treat it as a synchronous lookup
- ✗That same review found no agent-specific documentation despite the vendor site advertising an MCP server
- ✗Absent from the major head-to-head enrichment benchmarks — Openbenchmarks tests eight providers and SyncGTM nine, and this API is in neither — so no third-party accuracy or match-rate figure exists for it at all
- ✗Compliance floor is thin: no SOC 2, no SSO, no data residency and no self-hosted option, only a GDPR policy, a DPA and a 99.9% uptime claim
- ✗Company records include LinkedIn URLs and recent LinkedIn posts, and LinkedIn's litigation against Proxycurl — which went dark in July 2026 — makes that data provenance a live procurement question

List pricing is fully published, which is rare in this category. Plans meter monthly credits rather than calls, and each endpoint carries its own credit cost — 0.1 for Employee Finder up to 10 for the Funding API — so the real unit cost depends on which endpoints you call as much as on the tier. Effective rate swings roughly 6.5x across the ladder, from about $6.53 per 1,000 credits on the $49 Basic plan to about $1.00 per 1,000 on the $599 Business plan. Rate limits scale with the plan, from 2 requests per minute on the free tier to 70 on Business. Every plan unlocks every API, there are no contracts, annual billing adds two months, and only custom volumes require a sales conversation.
