ElysianPrimus Get a free key

Public data, cleaned and merged. One key for all of it.

ElysianPrimus gathers data from 25 official and open sources across the web and serves it as seven small, fast APIs for developers and AI agents. One record per lookup, over REST or MCP, priced for people who build.

Why one key

  1. One key works on every API. Sign up once. The same key calls CVE Intelligence, TradeCheck, LabelLink, SkillScan, EDGAR, HomeSignal and FireLine, and pays for all of them.
  2. REST and MCP from one schema. Each tool is one definition behind its REST route, its MCP tool and its OpenAPI entry, so they never drift. Agents add one connector, mcp.elysianintelligence.com/mcp, in Claude, ChatGPT and other MCP clients, and sign in with the key. How to connect
  3. Only successful calls count. Errors and your own bad requests are free. On MCP, only tool calls count; connecting and listing tools is free.
  4. Freshness is public. Every API shows when each dataset last loaded, and how many rows it holds, at /status. No key needed.

Prices

Free: 1,000 calls a month on each API. Pay as you go: $1 per 1,000 calls, prepaid, never expire (in place of the free calls). Starter: $19 a month. Pro: $99 a month. See every plan
