View URL, cURL & mcp.json

See the exact request first, then copy ready-to-run commands and MCP configs for terminals, scripts and agents.

Encrypted standalone links

Self-contained URLs for webhooks, automations and AI agents. No session, no friction.

Built-in CRUD

Read, write, edit and delete rows instantly. Zero SQL required.

Fully hosted, zero ops

No servers. No deploys. No MCP infrastructure. Your API and MCP tools are live the second you connect.

AI-native

Give your AI agents instant access to your data.

Every table becomes a clean, structured REST endpoint your AI agents, copilots and automations can call in seconds. No glue code. No custom backend. Just plug in and go.
