Do I need a Ocean.io account?

For 5 platform tools, no. The other 18 require your own Ocean.io key. All 23 accept your own key, and treg never meters BYOK calls.

What does a call cost?

Each tool on this page shows its rate. The rate is the provider's own and treg.to adds no markup; it is billed per call from a prepaid balance. It is not Ocean.io's subscription pricing, which is on their own site. New teams start with $1.00 of free credit.

How do I add Ocean.io to Claude Code?

Run: claude mcp add --transport http treg https://treg.tracea.online/mcp. One MCP server carries Ocean.io and the rest of the catalog.

Which frameworks does it work with?

Anything that speaks MCP (Claude Code, Claude Desktop, ChatGPT, Codex, Cursor, Grok) and anything that can make an HTTP request (LangChain, CrewAI, LlamaIndex, plain code).

Is this the official Ocean.io MCP server?

No. treg.to serves Ocean.io's real API through its own metered proxy: the request is the provider's own, the credential is injected server-side, and the answer is relayed verbatim. The official Ocean.io channels are linked above.
