## Known failure modes

- Invalid or malformed base58 pubkey returns an error result
- Unknown vote account or identity key returns empty or null result
- Neither vote nor identity param provided may return a validation error
- Network or payment failure causes 402 or 5xx response
- Rate limiting or USDC payment failure blocks the request
