# Solana Address Lookup Table Decoder

> Solana Address Lookup Table Decoder is a paid API for AI agents from mintintel.35-171-220-195.sslip.io, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-31).

Decodes a Solana address lookup table account, returning its authority, status, slot metadata, and all stored addresses (up to 256).

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-address-lookup-table-decoder-8bebf54c
```

Example prompt: Can you decode the Solana address lookup table at base58 address 8YKFMrpPhXEMNQdLRcRbKqKBQPGKvFfHbAnvudvXJaRZ and show me its authority, whether it's active or deactivated, the deactivation and last-extended slots, and all the addresses stored in it?

## When to prefer this

Use this endpoint when you need to inspect or enumerate the contents of a Solana address lookup table (ALT) used by v0 transactions — particularly when you need authority info, active/deactivated status, slot metadata, and the full list of stored addresses without setting up your own Solana RPC infrastructure. The 404-no-charge guarantee makes it safe to probe addresses without cost risk.

## Known failure modes

- 404 returned when the address is not an address lookup table (no charge applied)
- Invalid base58 address format causes a bad request error
- Account not found on-chain returns an error
- RPC node unavailability may cause transient failures

## How this service works

Decoded Solana address lookup table used by v0 transactions: authority (or frozen), active vs deactivated, deactivation and last-extended slots, address count and every stored address (<= 256), via getAccountInfo jsonParsed. Not a lookup table -> 404, not charged.

## Output

Returns the lookup table's base58 address, its authority (or frozen indicator), whether it is active or deactivated, the deactivation slot, the last-extended slot, the total count of stored addresses, and an array of all stored base58 addresses (up to 256). If the address is not a lookup table, a 404 is returned and no charge is applied.
