codex-data 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.
| HTTP endpoint | https://graph.codex.io/graphql |
| WebSocket endpoint | wss://graph.codex.io/graphql |
| Schema (SDL) | https://graph.codex.io/schema/latest.graphql |
| Introspection JSON | https://graph.codex.io/schema/latest.json |
| API-key auth | Authorization: <key> or Authorization: Bearer <token> |
Session preflight (required)
Run once and cache:
curl -sS https://graph.codex.io/graphql \
-H "Content-Type: application/json" \
-H "Authorization: $CODEX_API_KEY" \
--data-binary '{"query":"query GetNetworks { getNetworks { id name } }"}'
Use network IDs from this result before expensive requests.

Rules
- Never print raw API keys.
- Validate
networkIdfirst. - Keep selection sets minimal until shape is confirmed.
- Use
onPricesUpdatedinstead of many single-token subscriptions.
