## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability saylor-innovations-solana-wallet-profile-b2d54d5a
```

Example prompt: Can you pull a full profile for Solana wallet 7v91N7iZ9mNicL8WfG6cgSCKyRXydQjLh6UYBWwm1y2z — I want to see its age, first and last activity, failure rate, activity tier, and token account summary.

## When to prefer this

Choose this endpoint when you need a behavioral summary of a Solana wallet — not just a balance check — including historical activity signals like wallet age, failure rate, and activity tier. Prefer it over generic Solana balance lookups when doing due diligence, fraud screening, airdrop eligibility checks, or counterparty risk assessment on Solana addresses.

## Known failure modes

- Invalid or malformed Solana address returns an error or exists:false
- Wallet with no transaction history may return null for age and activity fields
- History may be marked incomplete if the RPC node cannot retrieve full transaction history for very active wallets
- Network or RPC unavailability may cause timeout or 5xx error
- Payment failure via x402 protocol returns 402 status before data is delivered

## How this service works

Solana wallet profile: true wallet age and first transaction, last activity, failure rate, activity tier, memo use and token account summary, from Solana RPC.

## Output

A JSON object containing chain identifier, wallet address, existence flag, account kind, SOL balance, total transactions seen, wallet age in days, first and last activity timestamps, transaction failure percentage, recent transactions per day, activity tier classification, memo usage count, token account count, non-empty token account count, history completeness flag, risk/status flags array, a contextual note, and the data source.
