## 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 vybe-solana-wallet-counterparties-endpoint-7859d8cc -d '<json body>'
```

Example prompt: Show me the top 20 counterparty wallets for Solana address 7v91N7iZ9mNicL8WfG6cgSCKyRXydQjLh6UYBWwm6y1Q over the last 7 days, sorted descending by total volume, grouped by wallet.

## When to prefer this

Use this endpoint when you need to understand the social or transactional graph of a specific Solana wallet — i.e. who it trades with, which programs it uses, and the relative volume of those relationships. It is the right choice over raw transfer history endpoints when you want aggregated counterparty-level summaries rather than individual transaction records. Prefer it for DeFi due-diligence, wallet profiling, bot detection, or identifying top trading partners.

## Known failure modes

- Invalid or malformed Solana wallet address returns a 400 or validation error
- Both sortByAsc and sortByDesc provided simultaneously causes a parameter conflict error
- No transactions found for the address in the time range returns an empty result set
- x402 payment not included or insufficient USDC balance causes a 402 Payment Required response
- Very large time ranges or high limit values may result in slower responses or timeouts

## How this service works

Read access to Solana on-chain data — tokens, wallets, markets, prices, trades, transfers. No API key, no signup. Pay in USDC per request with the x402 protocol; the per-route price is declared in `x-payment-info`. WebSocket streaming uses prepaid credits.

## Output

A paginated list of counterparty entries, each identifying a wallet address or program address that transacted with the queried wallet, along with aggregated metrics: total transfers, buy transfers, sell transfers, total volume, buy volume, sell volume, and net volume — all scoped to the requested time window.
