OpenWeb Ninja for AI agents

OpenWeb Ninja bundles native APIs for web search, e-commerce, finance, jobs, maps, and contact enrichment. Developers use it as a single source for many kinds of structured web data. Connect it once through Arc0, and your agent, or Claude, ChatGPT and Cursor, can use it through one MCP endpoint, limited to what each user approved.

How OpenWeb Ninja connects.

Users add their OpenWeb Ninja api key on Arc0 Connect. It is encrypted in the vault, never shown to the model, and each user can rotate or revoke it at any time.

The same OpenWeb Ninja connection serves your agent over MCP and your own backend over REST and the proxy, so a user connects once. How Arc0 handles credentials →
