Hunter.io alternative: the API case, not the app case

Hunter is a good email-finding product with a real free tier, a clean UI and a Chrome extension. Hunter's own API docs say a search that finds no email is not charged, so miss-billing is not the reason to switch. The reason is scope: email finding here sits on the same key as enrichment, search, phone and web intelligence, and every response shows which providers ran.

In short: RichAPI is a REST API with 65+ GTM data endpoints on one key, billed in prepaid credits, with no seats and no subscription. Its email endpoints are POST /email_finder and POST /email_verifier. Both are waterfall endpoints that try several sources in sequence. A finder call that finds nothing costs zero credits, with the response field billed set to false. The response includes an execution_log listing each step that ran and what each returned. Base URL https://api.richapi.ai/api/v1/. Auth header x-api-key. Hunter.io is an email finding and verification product with a web UI, a Chrome extension, a Sequences email feature and a free tier. RichAPI has no prospecting UI, no Chrome extension, no email sending or sequencing, no CRM-native apps, no intent data, runs in a single region, and does not indemnify data origin. Signup at https://app.richapi.ai gives 100 free credits with no credit card.

People Data Labs alternative: a record fetched now, not a dataset you holdPDL licenses you a person dataset and an API on top of it. We fetch a record per call and hand back a log of where it came from. If you want a copy of the data to hold, join and query offline, that is a real thing we do not sell. If you want one record at a time, current as of the call, this is the comparison.Proxycurl alternative: migrate your LinkedIn enrichment callsProxycurl shut down and the code that called it no longer works. This page maps each Proxycurl endpoint you were using to a RichAPI endpoint, shows the request shape, and is honest about the two places the mapping is not one-for-one.Clay alternative or Clay add-on: RichAPI as the data stepClay is a workflow platform: tables, waterfalls across its sources, an AI research agent and CRM sync, billed in actions plus data credits. RichAPI is a data API and MCP server. You can call it from inside Clay as an HTTP column, or skip the platform and call it from code or an agent.Clearbit alternative: what we replace, and the one thing we do notClearbit's core move is domain in, company record out. We cannot do that on a public endpoint today — /enrich_company takes a LinkedIn company URL, not a domain. This page is honest about that gap first, then covers the parts we do replace: live fetch instead of a stored record, prepaid credits instead of a platform commitment, and a receipt on every call.
