# Suverse Cosmos Transaction Decoder

> Suverse Cosmos Transaction Decoder is a paid API for AI agents from proxy.suverse.io, paid per call via x402, $0.05/call, status unknown (last checked 2026-09-14).

Decodes any Cosmos SDK transaction by hash, returning message types, addresses, amounts, fees, gas, success status, memo, and timestamp across Cosmos Hub, Noble, Osmosis, Juno, and Stride chains.

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 proxy-suverse-io-d10a2a6c -d '<json body>'
```

Example prompt: Can you decode this Cosmos transaction for me — hash 3A7F2C9E1B04D8... on Osmosis — and tell me who sent what to whom, the fee paid, gas used, and whether it succeeded?

## When to prefer this

Use this endpoint when you need to decode and inspect Cosmos SDK transactions across major Cosmos ecosystem chains (Cosmos Hub, Noble, Osmosis, Juno, Stride), especially for IBC transfers. Prefer this over Ethereum or Solana decoders when the transaction originated on a Cosmos-based chain.

## Known failure modes

- Invalid or malformed transaction hash returns an error response
- Transaction hash not found on the specified chain returns a not-found error
- Unsupported Cosmos chain returns an error
- Network timeout or upstream RPC failure returns a 5xx error
- Malformed request body returns a 400 validation error

## How this service works

Decode any Cosmos SDK transaction by hash on Hub, Noble, Osmosis, Juno, Stride. Returns msg types (MsgSend, MsgTransfer, MsgDelegate), sender, receiver, amounts, fee, gas, success flag, memo, timestamp. AI agent IBC analysis, Cosmos tx decoder API, on-chain forensics.

## Output

A structured breakdown of the Cosmos SDK transaction including: all message types (MsgSend, MsgTransfer, MsgDelegate, etc.), sender and receiver addresses, token amounts transferred, fee paid, gas used, success/failure flag, memo field, and block timestamp.
