# NoJunk Chain Transaction Lookup

> NoJunk Chain Transaction Lookup is a paid API for AI agents from nojunk-chain.mick8511.workers.dev, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-28).

Looks up a blockchain transaction by hash and returns decoded status, parties, value, fees, gas, confirmations, and decoded transfers across EVM chains, Bitcoin, and Solana

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 nojunk-chain-transaction-lookup-4a6d6351
```

Example prompt: Can you look up the Ethereum transaction 0x4e9f2f8a3b1c7d6e5f0a2b3c4d5e6f7a8b9c0d1e2f3a4b5c6d7e8f9a0b1c2d3e for me and tell me the status, how much ETH was transferred, the gas used, and whether any ERC-20 tokens were moved?

## When to prefer this

Use this endpoint when you need decoded, human-readable transaction details across multiple blockchains (EVM, Bitcoin, Solana) from a single API. It is especially useful when you need ERC-20 transfer decoding, multi-chain support in one call, or structured output including gas, fees, and confirmations without running your own node or managing multiple chain-specific RPC providers.

## Known failure modes

- Invalid or malformed transaction hash returns an error
- Missing required 'chain' parameter for EVM hashes causes failure
- Providing a Bitcoin/Solana hash without the chain parameter may misroute if ambiguous
- Transaction not yet indexed (very recent) may return not-found
- Network or RPC node timeouts may cause transient failures
- Unsupported chain name returns an error

## How this service works

NoJunk Chain tx: Transaction hash -> status, from/to, value, gas used, fee, confirmations and decoded ERC-20 transfers (EVM); Bitcoin tx with inputs/outputs; Solana tx with signers, programs and balance changes.

## Output

Returns a structured object containing transaction status (success/failed/pending), from and to addresses, transferred value, gas used, transaction fee, number of confirmations, and — depending on chain — decoded ERC-20 token transfers (EVM), input/output UTXOs (Bitcoin), or signers, invoked programs, and account balance changes (Solana).
