How It Works
StableEnrich bundles over 30 endpoints from Apollo, Clado, Exa, Firecrawl, Google Maps, Serper, Whitepages, and more into one pay-per-request interface. Each call is paid via x402 or MPP micropayments from your AgentCash wallet — no signup, no auth tokens.
Pick the endpoint you need, send a POST request with your query parameters, and get structured JSON back. Pricing ranges from $0.002 to $0.44 per request depending on the data source and depth of results.
People and Company Search
Use Apollo People Search to find prospects by job title, company, location, and other filters at $0.02 per request. Enrich individual contacts with email, phone, and employment data via Apollo People Enrichment for $0.0495.
For deeper contact intelligence, Clado Contacts Enrichment resolves LinkedIn URLs, emails, or phone numbers into full contact profiles at $0.20 per request. Minerva endpoints provide identity resolution, demographic data, work history, and financial signals.
Web Search and Content Retrieval
Exa Search provides neural web search at $0.01 per query, returning semantically relevant results. Exa Find Similar discovers pages related to any URL. Exa Answer generates AI-powered answers with source citations.
Firecrawl Scrape handles JavaScript-heavy pages that standard fetchers miss, at $0.0126 per page. Serper endpoints cover Google News and Shopping search results. Reddit Search and Post Comments endpoints let you tap into community discussions.
Location and Property Data
Google Maps endpoints support text search, nearby search, and place details at varying price tiers. Partial results start at $0.02 and full results at $0.05–$0.08 per request.
Whitepages endpoints provide person search and property ownership data including resident information at $0.44 per lookup.
Identity and Email Verification
Hunter Email Verifier checks deliverability at $0.03 per address. Minerva Validate Emails confirms whether addresses exist in the Minerva database with last-seen timestamps at $0.01 per check.
Influencer enrichment endpoints map email addresses to social media profiles or expand social profiles with contact info, both at $0.40 per request.

Frequently asked questions
What authentication is required?
No API keys or account signups are needed. Requests are paid via x402 or MPP micropayments directly from your AgentCash wallet. The payment is embedded in the HTTP request itself.
How is pricing structured?
Every endpoint has a fixed per-request price in USD, ranging from $0.002 for Exa Contents to $0.44 for Whitepages lookups. You pay only for successful requests — no monthly minimums or subscriptions.
What data format do responses use?
All endpoints return structured JSON. Request and response schemas follow the conventions of the underlying data provider, so Apollo endpoints return Apollo-style objects, Google Maps endpoints return Google-style place data, and so on.
Can AI agents call these endpoints directly?
Yes. The pay-per-request model with no auth setup makes these endpoints ideal for autonomous AI agents. Any agent with an AgentCash wallet can discover and call endpoints without human intervention.
How do Cloudflare crawl jobs work?
POST to the Cloudflare crawl endpoint to start a job and receive a polling token. Then GET the jobs endpoint with that token to check status and retrieve results. Only the wallet that initiated the crawl can poll for results.
What happens if an endpoint returns an error?
Payment is only charged for successful responses. If the underlying data source returns an error or no results, check the specific endpoint documentation for its error handling and retry behavior.
