How to Resolve capability_unavailable

1. Inspect the status (503), code (capability_unavailable), and detail fields in the JSON response.
2. For 400 validation errors (invalid_*), verify query parameters against the Endpoints Reference or Statistics Catalog (GET /v3/statistics).
3. For 404 errors (*_not_found), confirm the resource exists on Stellar Pubnet.
4. For 409, 429, 503, or 504 transient states, retry with exponential backoff.
