## 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 solana-account-meta-analyzer-5a2fe0ff -d '<json body>'
```

Example prompt: Can you analyze these Solana transaction account metas and tell me which accounts are signers, which are writable, and whether there are any duplicate keys? Here's the account metadata JSON: [{"pubkey":"11111111111111111111111111111111","isSigner":true,"isWritable":true},{"pubkey":"TokenkegQfeZyiNwAJbNbGKPFXCWuBvf9Ss623VQ5DA","isSigner":false,"isWritable":false}]

## When to prefer this

Choose this endpoint when you need to programmatically parse and summarize Solana transaction account metadata — particularly to identify which accounts hold signer or writable privileges, detect duplicate public keys, or count account roles. It is ideal for pre-submission transaction auditing, DeFi bot development, and on-chain security analysis pipelines. Prefer it over manual parsing when working with complex multi-account Solana instructions where role clarity matters.

## Known failure modes

- Malformed or invalid JSON in request_json returns a parse error
- Account metadata missing required fields (pubkey, isSigner, isWritable) may produce incomplete analysis
- Caller-supplied metas may omit inner-instruction privileges, leading to incomplete privilege analysis (warned in output)
- Input exceeding 65536 characters is rejected
- Empty or minimal JSON input may return an empty accounts list

## Output

Returns a structured JSON analysis including: a list of all accounts with their public keys, signer/writable flags, and associated instruction indexes; a count of unique accounts, signers, and writable accounts; a list of any duplicate public keys; the analyzed network (Solana); and an evidence scope warning noting that metas are caller-supplied and may omit inner-instruction privileges.
