# ApiOne

> ApiOne (apione.store, also written "API ONE") is a B2B data enrichment REST API. One API key covers company enrichment and search, people enrichment and search, email finding and verification, tech stack, business signals, hiring signals, and Arabic/English company name matching. Every enriched field carries cited sources in `_meta.sources`. It is built for companies that Western databases cover poorly, especially GCC and MENA businesses (UAE, Saudi Arabia, Qatar, Kuwait, Bahrain, Oman, Egypt, Morocco). Not affiliated with apione.org.

Key facts:
- Base URL: https://api.apione.store/api/v1 , auth via `X-API-Key` header
- Free tier: 100 credits, no card. Paid: Starter $49/month (5,000 credits), Growth $149/month (25,000), Scale $499/month (100,000). Billing via PayPal.
- Honest-null policy: when a value cannot be verified the field returns null, and a genuine miss is not charged.
- MCP server: https://apione.store/mcp?api_key=YOUR_KEY (Streamable HTTP, 11 tools)
- Status: https://apione.store/status
- Typical latency: company enrichment 5 to 9 s (live-sourced), email find about 2.5 s, people about 1.5 s, verify 1 to 2 s.
- Good fit: enriching GCC/MENA accounts, standalone Clearbit API replacement without HubSpot, adding a MENA layer to a waterfall enrichment stack.
