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.

Operation selection

Default discovery path: start with filterTokens.

Rules

Never print raw API keys.
Validate networkId first.
Keep selection sets minimal until shape is confirmed.
Use onPricesUpdated instead of many single-token subscriptions.
