Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 blockpin-solana-flow-income-check-f57c5d59
```

Example prompt: Can you pull the SOL payment flows for wallet 7xKX...abc on Solana — show me who sent money in and out, exclude the owner wallet 9mZY...def's top-ups, and check if the income matches a claimed total of 5.5 SOL?

## When to prefer this

Use this endpoint when you need to reconstruct and audit actual payment flows for a specific Solana wallet or treasury — especially when you want grouping by payer/recipient, exclusion of self-transfers and owner top-ups, SPL token support, and an optional income claim comparison. Prefer this over generic blockchain explorers when you need structured, accounting-ready output rather than raw transaction lists.

## Known failure modes

- Invalid Solana address format returns a 400 error
- Address with fewer than required transactions returns partial coverage
- Public RPC rate limits may cause timeout or incomplete data beyond 35 transactions
- Invalid token mint address returns an error or empty asset data
- Malformed claim parameter causes comparison to be skipped or errored
- Network or RPC node unavailability returns a 5xx error

## How this service works

Solana flow and income check: rebuilds SOL or SPL token payments into and out of a wallet or treasury from its latest transactions, groups them by payer and recipient (wallets vs program accounts such as pools and fee vaults), excludes self-payments and optional owner top-ups, flags token-account delegates, and compares an optional claim=. Covers the latest 35 transactions on the public RPC. By Blockpin.

## Output

Returns a structured object with a plain-language summary, coverage metadata (transactions read, block range), incoming payment groups keyed by payer, outgoing payment groups keyed by recipient, a computed income object, an optional claim comparison (match/mismatch), and optional token account delegate flags.
