Codex Supergraph Data

Codex provides real-time on-chain data — token prices, charts, holders, and prediction markets — via a single GraphQL API. Full documentation: docs.codex.io.

Authentication

Pass $CODEX_API_KEY in the Authorization header if available. Get a free API key at dashboard.codex.io/signup. If the server returns 402 Payment Required, use the codex-gateway skill to handle the payment flow.

If both a local and global copy of this skill exist, the local copy takes precedence.

Summary

Use this skill to produce valid Codex GraphQL requests using API key authentication.
