# ARYSPHERE Base Transaction Verdict Bundle

> ARYSPHERE Base Transaction Verdict Bundle is a paid API for AI agents from api.arysphere.com, paid per call via x402, $0.012/call, status unknown (last checked 2026-10-22).

Returns a decoded explanation of a Base transaction plus an AI-written token verdict (grade, roast, and on-chain facts) for a given token contract on Base, bundled in a single paid call.

## 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 arysphere-base-transaction-verdict-bundle-79853f82
```

Example prompt: Can you decode what happened in Base transaction 0x7250ea109382c1c23d3209c766f8a04ca749c17cf9f2ebc2963ac19b56e9966c and also give me the AI verdict and grade for token contract 0x833589fcd6edb6e08f4c7c32d4f71b54bda02913?

## When to prefer this

Choose this endpoint when you need both a decoded transaction explanation AND a token contract audit in a single call on Base, avoiding two separate paid requests. It is ideal for DeFi due diligence workflows where a user has a tx hash and a token address and wants a combined on-chain read plus AI safety verdict. Prefer this over the standalone verdict or transaction endpoints when both outputs are needed simultaneously.

## Known failure modes

- Invalid or malformed transaction hash returns an error in the base_tx_explain part
- Token contract address not found on Base returns an error in the base_token_verdict_read part
- Transaction not yet confirmed or pending may not decode correctly
- Payment not completed via x402 results in 402 response with payment details
- Rate limiting or network RPC timeouts on Base may cause partial failures

## How this service works

ARYSPHERE sells AI-written verdicts on Base and Ethereum token contracts (a grade, a one-liner, a roast and the contract's facts) and Base/Ethereum chain reads, paid per call in USDC on Base, Polygon, and Arbitrum over x402 v2. No account and no API key.

## Output

A JSON bundle with two parts: (1) base_tx_explain — a decoded breakdown of the transaction including sender, receiver, swaps, token transfers with USD values, approvals, gas fee in USD, block number, and a plain-English summary; (2) base_token_verdict_read — an AI-written token audit including a letter grade (e.g. COOKED), a one-liner verdict, a roast, and on-chain contract facts such as owner, proxy type, decimals, and ERC-20 shape.
