# paypi Solana Transaction Decoder

> paypi Solana Transaction Decoder is a paid API for AI agents from pay.ansht.tech, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-16).

Decodes a Solana transaction by signature or raw base64, returning a human-readable summary of its instructions and programs involved

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 paypi-solana-transaction-decoder-657c15fe
```

Example prompt: Can you decode this Solana transaction and tell me what instructions it ran? The signature is 5v3G...XkPq on mainnet.

## When to prefer this

Choose this endpoint when you need a quick, paid-per-use decode of a Solana transaction by signature or raw bytes without setting up your own RPC infrastructure. It's ideal for AI agents that need on-demand, human-readable summaries of Solana instructions without managing Solana node connections or parsing binary transaction formats manually.

## Known failure modes

- Invalid or malformed transaction signature returns an error in the 'err' field
- Unknown or unrecognized program IDs may result in incomplete instruction labeling
- Specifying the wrong cluster (mainnet vs devnet) for a given signature will cause lookup failure
- Malformed base64 body will result in a parse error
- Network or RPC node unavailability may cause timeout or upstream errors

## How this service works

Decode a Solana transaction into structured instructions, program ids (named), accounts and a human summary. Accepts a base64 serialized transaction (offline) or a landed signature (RPC jsonParsed). Use before signing/sending, or to understand a landed tx.

## Output

Returns a JSON object with an error field (null if successful), the source type (signature or raw), and a human-readable summary listing the number of instructions and the programs invoked (e.g. System Program, SPL Token). Additional decoded instruction details may be included.
