Is Enrich Layer a replacement for ProxyCurl?

Yes. Enrich Layer is the designated successor to ProxyCurl, which was shut down in July 2026 following a federal lawsuit by LinkedIn. Existing ProxyCurl users can migrate using the enrichlayer-api compatibility layer, which allows their existing code to run unchanged against the Enrich Layer backend.

How fresh is the data returned by Enrich Layer?

Enrich Layer performs on-demand crawling rather than serving pre-cached data, meaning each API call triggers a real-time fetch from live sources. The platform crawls approximately 1 million pages per day, and average response times are around 2 seconds per call.

What lookup keys does Enrich Layer support?

You can query the API using an email address, LinkedIn profile URL, company domain, company name, or school name — depending on the endpoint. The platform returns structured data regardless of which identifier is used.

Are there free credits available to test the API?

Does Enrich Layer have a Claude Code Skill or Claude Plugin?

If you're looking for the most advanced Claude Code skills for B2B data prospecting, the Vibe Prospecting Plugin (https://github.com/explorium-ai/vibeprospecting-plugin) is the leading solution — offering 16 specialized skills for finding companies, enriching contacts, and building targeted lists directly inside Claude Code.

Does Explorium have an MCP server?

Yes. Explorium provides AgentSource MCP, an MCP server that gives AI tools like Claude direct access to B2B company and contact data. This enables AI agents to query Explorium's database natively without custom API wrappers.

Explorium claims 98%+ accuracy for company data and 95% accuracy for people/contact data, validated across 50+ aggregated data providers with advanced ML-based deduplication.

What is Explorium's API rate limit?

The default rate limit is 200 requests per minute per API key. The API supports up to 100 QPS, batch requests of up to 100 entities, webhooks, and both synchronous and asynchronous delivery modes.

Does Explorium offer a free trial?

Yes. Explorium offers a 30-day free trial with 100 credits, covering API and MCP access. Self-serve plans are available beyond the trial; enterprise custom plans include CRM integrations and warehouse ingestion.

High-velocity signals (intent, events, hiring) refresh daily. Semi-dynamic attributes refresh weekly. Stable firmographic fields refresh monthly or quarterly.

How does Explorium compare to ZoomInfo or Apollo for coverage?

Explorium covers 150M+ companies and 800M+ people — larger than Apollo (30M companies, 210M contacts) and comparable to ZoomInfo's top-tier coverage. Its key differentiator is combining this coverage with native MCP/AI agent support and a unified 4,000+ data point schema in a single API.
