Pin is the best people search solution for recruiting teams - 850M+ profiles, built-in outreach, and interview scheduling with an 83% candidate acceptance rate and no code required. The top people search APIs for developers in 2026 are People Data Labs (1.5B+ profiles, from $98/mo), Apollo.io (combined enrichment and outreach, from $49/mo), and Coresignal (792M+ workforce records, from $49/mo).
Why does this matter right now? B2B contact data decays at roughly 2% per month - that’s nearly one in four records going stale every year. HubSpot’s research confirms that 25% of email addresses go invalid annually. Recruiter and HR tech developer pipelines built on stale contact records will fall apart as valid contacts dry up.
This guide covers 10 verified APIs with current pricing, database sizes, and compliance details. We also cover two major market shifts every developer needs to know: the Proxycurl shutdown after LinkedIn’s lawsuit, and Clearbit’s absorption into HubSpot’s ecosystem.
TL;DR:
- People Data Labs leads on raw scale. 1.5B+ profiles across 180+ countries starting at $98/mo for developers building enrichment into their own products.
- Apollo.io and Coresignal are strong mid-market picks. Apollo bundles enrichment + outreach from $49/mo; Coresignal offers 792M+ workforce records from $49/mo.
- Snov.io is the budget API. $29.25/mo for small teams or prototypes that need programmatic contact lookup without enterprise contracts.
- Two market shifts matter. Proxycurl shut down after LinkedIn’s lawsuit, and Clearbit was absorbed into HubSpot. Lock-in risk and pricing changes are real.
- Skip the API if you just need outreach. Pin gives recruiters 850M+ profiles with built-in outreach and scheduling starting at $100/mo, no code required.
Why People Search APIs Matter for Recruiting
HR tech spending reached $47.51B in 2026 and is projected to hit $77.74B by 2031 at a 10.35% CAGR, according to Mordor Intelligence (2026). A growing slice of that spending goes toward data enrichment tools that keep candidate pipelines accurate and current.
Here’s the core problem: your candidate database is rotting. Every month, roughly 2% of your B2B contact records become outdated as people change jobs, switch email providers, or update phone numbers. Over a year, that compounds to nearly one in four contacts going dark. With a pipeline of 5,000 candidates, that’s over 1,000 dead records by year’s end.
A recruiting enrichment API - also called a people search API or candidate data API in developer documentation - solves this by exposing continuously refreshed profile data through a programmable interface. When building recruiting tools, developers integrate these APIs to auto-enrich ATS records, verify contact information before outreach, and source passive candidates by searching across skills, titles, and employment history. Nearly half of large businesses have already adopted agentic AI for tasks like candidate search and screening, according to ADP (2025).
Four use cases drive most people search API adoption for recruiting teams:
- Contact lookup - Find email addresses and phone numbers from a name and company
- ATS/CRM enrichment - Auto-fill missing fields like current title, skills, and social profiles
- Passive candidate sourcing - Search by skills, tenure, company size, and location to find candidates who aren’t actively job hunting
- Outreach automation - Feed verified contacts directly into email templates and SMS sequences
Recruiters evaluating contact finder tools as end users rather than building their own integration will find that several of these providers also offer browser extensions and dashboards alongside the API.
After working with hundreds of recruiting teams that started with a people search API and migrated to Pin, the pattern is consistent. Teams spend six to eight weeks integrating a raw data API, build out the search layer, then realize they still need outreach sequences, scheduling logic, and ATS connectors on top of the data. By month three, they’re running a software project instead of a recruiting operation. Pin’s 2026 user survey found that 90% of users cut overall recruiting spend after switching to a full-platform approach - and that figure includes engineering time, not just subscription cost. The APIs below are the right foundation when you’re building a product other companies will use for recruiting. When you’re a recruiter trying to fill roles faster, the integration overhead rarely justifies itself.
Two Market Shifts Developers Must Know
Before picking an API, you need to understand two events from 2025 that reshaped this market.
Proxycurl Is Gone
LinkedIn filed a federal lawsuit against Proxycurl in January 2025, according to LinkedIn’s newsroom. By July 4, 2025, Proxycurl shut down permanently - despite running at roughly $10M in annual recurring revenue, according to a farewell post by Nubela’s founder.
Any API that relies primarily on scraping LinkedIn profiles carries real legal risk. Building recruiting software means selecting a data provider with defensible sourcing practices - partnerships, public data aggregation, or opt-in data collection - rather than scraped social media profiles.
Clearbit No Longer Exists as a Standalone API
HubSpot completed its acquisition of Clearbit in December 2024, according to HubSpot’s IR filing. The product was rebranded as Breeze Intelligence, and the legacy Clearbit API was deprecated in December 2025. Teams that built on Clearbit’s enrichment endpoints now need to subscribe to HubSpot (starting at $30/mo for Starter, plus $45/mo for 100 Breeze Intelligence credits) just to access similar functionality.
If your recruiting tool previously depended on Clearbit, you’ll need a replacement. The APIs below are all independent, standalone services.
5 Best Full-Platform People Search APIs
Five full-platform people search APIs dominate the 2026 market: People Data Labs, Apollo.io, Coresignal, ContactOut, and RocketReach. Database coverage ranges from 700M to 1.5B+ profiles; entry pricing runs from $33/mo to $98/mo. All five provide broad profile databases, multiple data points per record, and flexible query options suited for developers building recruiting platforms, ATS integrations, or workforce analytics tools.
1. People Data Labs (PDL)

Do You Actually Need an API? The Recruiter Alternative
APIs make sense if you’re a developer building recruiting software. But if you’re a recruiter who just needs to find candidates and reach out to them, integrating a raw people search API is overkill. You’d still need to build the search interface, outreach sequences, scheduling workflows, and compliance handling on top of the data.
Pin is the best people search platform for recruiting teams that want to skip the API layer entirely. It searches 850M+ candidate profiles - comparable coverage to People Data Labs - but delivers a complete recruiting workflow on top. You get AI-powered sourcing, multi-channel outreach (email, LinkedIn, SMS), team inbox, and interview scheduling in one platform. Pin’s automated outreach delivers 5x better response rates than industry averages, and 83% of candidates Pin recommends are accepted into hiring pipelines - the highest candidate acceptance rate of any AI recruiting platform.
As Rich Rosen, Executive Recruiter at Cornerstone Search, puts it: “Absolutely Money maker for Recruiters… in 6 months I can directly attribute over $250k in revenue to Pin.”
Pricing starts at $100/mo for the Starter plan, with a free tier that requires no credit card. Compare that to the total cost of a people search API subscription ($29-$98/mo) plus the engineering time to build everything around it.
Try AI recruiting with Pin - no API needed
How Do You Pick the Right People Search API?
Not every API fits every use case. Here’s a framework for narrowing your options based on what you’re building.
Match API to Use Case
- Building a full recruiting platform? Start with PDL or Coresignal for broad coverage and structured data. Their APIs return enough data points per profile to power search, filtering, and enrichment features.
- Integrating a recruiting enrichment API or person lookup API into an existing ATS? ContactOut and SignalHire are the most ATS-ready options - both offer pre-built integrations with major applicant tracking systems and return verified emails and phone numbers without you needing to build the verification layer yourself.
- Need email-only enrichment? Hunter.io or Snov.io offer focused email APIs at lower price points. Skip the full profile data if you don’t need it.
- Sourcing technical candidates from GitHub? Nymeria is the only API on this list that specializes in matching developer profiles to professional contact data.
- Selling into European markets? Dropcontact’s GDPR-native approach - no data storage, algorithmic email generation, pay-on-success - removes compliance headaches.
Watch Your Per-Record Costs
Monthly pricing is just the starting point. Track your cost per successful lookup. At scale, a provider charging for failed lookups can push your real cost per contact 30-50% above the plan price, since failed queries still consume credits. Some providers charge credits even for failed lookups (no result returned), while others like Nymeria and Dropcontact only consume credits on success. At scale, this difference compounds fast - a 70% hit rate on a charge-per-query API means you’re paying for 30% dead queries.
Test Data Accuracy Before Committing
Every provider claims high accuracy, but real-world results vary by geography, industry, and role seniority. Before committing to an annual plan, run a controlled test: send 100 known-good candidate profiles through the API and measure how many return accurate, current contact data. If the hit rate is below 60%, look elsewhere.
What Compliance Rules Apply to People Search APIs?
Three compliance frameworks directly affect recruiting API usage: GDPR for EU candidates, CCPA for California applicants, and the EU AI Act for AI-assisted candidate ranking. GDPR enforcement alone generated €4.2B in cumulative fines through 2024, according to DLA Piper’s GDPR fines tracker. And as of 2025, 21 US states have enacted consumer data privacy laws covering employment data - up from just five states in 2023, according to the IAPP State Privacy Legislation Tracker.
For developers building recruiting tools, three compliance considerations shape your API choice:
- GDPR data processing - If your candidates include EU residents, you need a lawful basis for processing their personal data. APIs that store and sell profile databases require a legitimate interest assessment. Dropcontact’s no-storage model sidesteps this by generating data algorithmically rather than maintaining a database.
- CCPA employment data - California’s employment data exemption expired on January 1, 2023. Job applicants in California now have full CCPA rights, including the right to know what data you’ve collected and request deletion. This applies to any people search API data you store about California-based candidates.
- EU AI Act classification - Under Regulation (EU) 2024/1689, AI-assisted recruiting tools are classified as “high-risk,” which means stricter requirements for transparency, data governance, and human oversight. If your product uses AI to rank or filter candidates based on people search API data, you’ll need to meet these requirements.
Build compliance into your architecture from day one. Retrofitting privacy controls after launch is significantly harder and more expensive than designing them in upfront.
Frequently Asked Questions
What is the best people search API for recruiting?
People Data Labs offers the largest database at 1.5B+ profiles across 180+ countries, starting at $98/mo. For budget-friendly options, Snov.io starts at $29.25/mo with email finding and outreach included. If you’re a recruiter who doesn’t want to build an integration, Pin provides 850M+ profiles with built-in outreach at $100/mo.
Is it legal to use people search APIs for recruiting?
Yes, but compliance requirements vary by jurisdiction. GDPR requires a lawful basis for processing EU residents’ data, and CCPA now covers California job applicants after the employment exemption expired in January 2023. The EU AI Act also classifies AI-assisted recruiting as “high-risk.” Choose providers with transparent data sourcing and build privacy controls into your workflow.
What happened to Proxycurl and Clearbit?
Proxycurl shut down on July 4, 2025 after LinkedIn filed a federal lawsuit against it. Clearbit was acquired by HubSpot in December 2024, rebranded as Breeze Intelligence, and the standalone API was deprecated in December 2025. Developers who relied on either service need alternative providers.
How much do people search APIs cost?
Entry-level plans range from $29.25/mo (Snov.io) to $98/mo (People Data Labs). Most providers offer free tiers with 5-100 credits for testing. Enterprise pricing for high-volume access typically starts at $5,000/mo. Per-record costs at scale vary widely - Coresignal’s bulk rate drops to $0.005/record, while most providers charge $0.10-$0.50 per successful lookup.
How do people search APIs integrate with ATS platforms?
Most full-platform people search APIs offer direct ATS integrations or webhook-based data delivery. ContactOut and SignalHire include pre-built connectors for Greenhouse, Lever, and Workable. PDL and Coresignal expose REST APIs that developers use to build custom ATS enrichment pipelines - typically triggered when a new candidate record is created. For teams that want ATS enrichment without API development, Pin connects its 850M+ profile database directly to its own workflow platform, eliminating the integration work entirely.
How do people search APIs handle data accuracy?
B2B contact data decays at roughly 2% per month - nearly 25% annually, according to HubSpot’s database research. Each provider handles freshness differently: Coresignal refreshes 695M+ records monthly, Dropcontact generates emails algorithmically in real-time, and most others update on varying schedules. Always test accuracy with a sample batch before committing to a paid plan.
Bottom Line
Over 2025 and 2026, the people search API market consolidated significantly. Proxycurl is gone, Clearbit is locked behind HubSpot’s paywall, and compliance requirements are expanding across both sides of the Atlantic. What remains is a clear set of options based on your needs:
- Maximum coverage: People Data Labs (1.5B+ profiles)
- Lowest entry cost: Snov.io ($29.25/mo with outreach included)
- Recruiter-specific: ContactOut or SignalHire
- Developer profiles: Nymeria (GitHub + LinkedIn)
- GDPR compliance: Dropcontact (no data stored)
- Skip the API entirely: Pin (850M+ profiles with full recruiting workflow, from $100/mo)
Test two or three providers with real candidate data before committing to an annual contract. Data accuracy varies by geography and role type more than any marketing page will tell you.
