Best People Search APIs in 2026: Treg, Apollo & More

1. Comparison dimensions

When teams shortlist people search APIs, they usually compare: search capabilities, returned data types, API documentation quality, pricing model, integration complexity, developer experience, and AI-agent compatibility.

This article uses publicly described product categories. We do not invent accuracy percentages, profile counts, or unpublished price tables. Verify current pricing on each vendor’s site before buying.

2. Treg (routed agent tools)

Treg markets an OpenRouter-style catalog for agent tools, including people-search / enrichment routes behind one token. Published materials emphasize pay-per-answer metering and agent workflows (often with decision models such as Jev for ICP gating).

Strength for agents: one integration surface across many providers. Tradeoff: you inherit upstream provider coverage and capacity; catalog prices change; self-host vs hosted Treg terms differ.

3. Other products teams often compare

Do not treat this list as an endorsement ranking. Capabilities, pricing, and terms change. Prefer primary docs over third-party summaries (including this unofficial community site).

• Apollo — sales intelligence / enrichment suite with its own APIs and UI; strong CRM-oriented workflows; separate contract from Treg.
• People Data Labs — people/company data APIs; schema and coverage are PDL-specific.
• Crustdata / similar B2B data APIs — evaluate freshness, fields, and ToS for your use case.
• Exa — neural/web search oriented APIs; overlapping “find people/companies” intent but different product shape than classic enrichment.
• Perplexity / LinkupAPI-style answer or search APIs — useful for research agents; not drop-in replacements for verified work-email find.
• Hunter and similar finders — often appear inside Treg waterfalls in published receipts; you can also buy them directly.

4. What jevtypesafe.org actually offers

This independent host exposes POST /api/v1/people/email/find on prepaid jv_live_ keys, relaying to Treg’s routed email-find. Decide remains available for ICP-style gates. We are not affiliated with Treg, Apollo, PDL, Exa, Perplexity, or TypeSafe AI.

Retail metering on this host differs from Treg catalog pricing. Read the landing and docs before comparing “cost per email” screenshots from vendor marketing.

5. How to choose

• Need one agent catalog across many tools? Evaluate Treg (direct) or a host that already meters it.
• Need a full sales workspace UI? Evaluate Apollo-class suites directly.
• Need raw people graph queries? Evaluate PDL-class data APIs.
• Need web/neural search for research agents? Evaluate Exa / answer APIs — then add a dedicated email verifier if required.
• Need decide + email-find under one prepaid key on this host? Use the People Search API here after reading Terms and Privacy.
