What is Hunter

Vendor's own claim

Hunter is a B2B contact-discovery and outreach platform built around a large index of publicly available professional email addresses.

Ideal customer profile

Vendor's own claim

Sales, growth, and lead-gen teams doing B2B outreach who need to find and verify contact emails at a company before or during a campaign; Hunter names Canva, Semrush, and Vimeo as customers.

Who should look elsewhere

Our read

The Free plan gives only 50 credits/month, which covers a handful of lookups, not a working prospecting workflow; a usable volume starts at the $49/mo (or $34/mo annual) Starter plan and scales to $299/mo for 25,000 credits. Teams that need bulk data access rather than a seat-based outreach tool are pushed into a separate 'Data Platform' bulk-credit package (e.g. $6,500 for 1,000 search + 200,000 verification credits) priced and sold outside the standard plan ladder. Buyers who specifically want an OpenAPI-documented, spec-driven integration will not find a published machine-readable spec on Hunter's own docs.

Hunter FAQ

Is there a published OpenAPI or Swagger spec?

No machine-readable OpenAPI/Swagger file was found linked from Hunter's own API documentation page; the docs are prose-and-example based.

Our read
Does Hunter have an MCP server for AI agents?

Yes.

From official docs
Is there a free plan?

Yes, a Free plan with 50 credits/month, unlimited team members, and 1 connected email account, though the credit allowance is too small for sustained prospecting.

From official docs
How is Hunter priced?

Per-workspace monthly or annual subscription tiered by credits: Free ($0, 50 credits), Starter ($49/mo or $34/mo annual, 2,000 credits), Growth ($149/mo or $104/mo annual, 10,000 credits), Scale ($299/mo or $209/mo annual, 25,000 credits), and custom-priced Enterprise. A separate bulk-credit Data Platform package (e.g. $6,500 for 1,000 search + 200,000 verification credits) is sold outside this ladder for API-heavy use.

From official docs
What authentication does the API use?

An API key, which can be supplied as the api_key query parameter, an X-API-KEY header, or an Authorization: Bearer header.

From official docs
What are Hunter's API rate limits?
