# Solana Token-2022 Extensions Parser

> Solana Token-2022 Extensions Parser is a paid API for AI agents from signalharness.ai, paid per call via x402, $0.015/call, status unknown (last checked 2026-09-13).

Parses and decodes Solana Token-2022 account extension data from raw JSON, identifying extension types, configurations, and any anomalies.

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 solana-token-2022-extensions-parser-5a8d296f -d '<json body>'
```

Example prompt: Can you parse this Solana Token-2022 mint account JSON and tell me what extensions are configured on it, including any transfer fee or interest-bearing settings?

## When to prefer this

Use this endpoint when you need to programmatically inspect the extension configuration of Solana Token-2022 accounts, especially for DeFi integrations, token audits, or building tooling that must understand transfer fees, interest rates, confidential transfers, or other SPL Token-2022 extension types. Prefer this over manual RPC calls when you need structured, agent-consumable output with explicit extension typing.

## Known failure modes

- Unknown or non-standard binary extension layouts cannot be decoded without typed records — returned as unknown_types with a warning
- Malformed or truncated JSON input may cause parse failures
- Extension data exceeding 65536 characters will be rejected by input length limit
- Non-Token-2022 accounts passed as input may produce incorrect or empty extension lists

## Output

Returns a structured analysis including the account type (mint or token), a list of decoded extensions with their types and configurations (e.g. transfer_fee_config with basis_points), any duplicate extension entries found, any unknown extension types that could not be decoded, and parser warnings. Also includes a receipt with payment details and a SHA-256 hash of the result for verification.
