## How to call it through Zero

```sh
zero fetch --capability solana-validator-lookup-risk-screening-d3f9ff10
```

Example prompt: Can you look up the Solana validator with vote-account pubkey 5ZWgXcyqrrNpQHCme7js9MQ3mDpVFjdT7LRvJbgQhxnK and tell me its identity and risk level? Also give me the top 5 lowest-risk validators.

## When to prefer this

Choose this endpoint when you need to resolve Solana validator pubkeys (vote-account ↔ identity) combined with OFAC compliance screening and risk ranking in a single call. It is especially suited for institutional staking workflows, compliance-gated delegation decisions, or agent pipelines that need to programmatically select low-risk validators without manual research.

## Known failure modes

- Invalid or malformed pubkey returns error in result object
- Unknown pubkey not found on-chain returns empty or null result
- top_n value outside 1-50 range rejected with validation error
- Network or upstream data unavailability returns non-success response
- Payment failure (insufficient USDC) blocks access entirely

## How this service works

X402 micropayments server — AI agents pay USDC for OFAC screening, rates, and billing verification.

## Output

Returns a JSON object with success flag and a result containing resolved validator details (identity pubkey, vote-account pubkey), OFAC screening status, risk score, and optionally a ranked list of the top N lowest-risk safe validators on the Solana network.
