cex-api-orchestrator - SKILL.md Agent Skill

name: cex-api-orchestrator description: "Use when tasks must coordinate CEX report data across CoinGecko, CMC, Deribit, Coinglass, Glassnode, Nansen, Santiment, and Alternative.me with capability checks and fallback routing."

Use this as the top-level planning skill for report generation.

Route each metric to the best available API source without failing the full report when one endpoint is blocked.

CoinGecko:
- Pro test on pro-api with /key
- If error code 10011, switch to Demo route
CMC:
- Read /key/info
- Build allowed endpoint set
Deribit:
- Probe one known method (public/ticker) and continue if reachable
Coinglass:
- Check COINGLASS_API_KEY exists
- Probe one endpoint and classify plan capability by returned error
Glassnode:
- Check GLASSNODE_API_KEY exists
- Probe one metric path and classify tier by returned error
Nansen:
- Check NANSEN_API_KEY + NANSEN_BASE_URL
- Probe one endpoint and classify capability
Santiment:
- Check SANTIMENT_API_KEY
- Run GraphQL probe and classify capability
Alternative.me:
- Probe /fng/ as no-key sentiment fallback
