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.
Example use cases
DeFi swap audit and token safety check
“I just swapped on Base — transaction hash is 0x7250ea109382c1c23d3209c766f8a04ca749c17cf9f2ebc2963ac19b56e9966c. Can you break down exactly what happened and also tell me if the token I received at 0x1f16e03c1a5908818f47f6ee7bb16690b40d0671 is safe to hold?”
Token contract due diligence before investing
“Before I put money into this token on Base, can you pull up the AI verdict and grade for contract 0x1f16e03c1a5908818f47f6ee7bb16690b40d0671 and also decode this transaction I saw involving it: 0x7250ea109382c1c23d3209c766f8a04ca749c17cf9f2ebc2963ac19b56e9966c?”
Suspicious transaction investigation
“Someone sent me a Base transaction hash — 0x7250ea109382c1c23d3209c766f8a04ca749c17cf9f2ebc2963ac19b56e9966c — and I want to know what it actually did on-chain and whether the token contract 0x8ea5ad2a58c1dae75394b1e8636e6518eb6dac50 involved is sketchy or legit.”
Technical details
Endpoint
GEThttps://api.arysphere.com/v1/ventures/x402_chain_reads_v1/base_tx_verdict_bundle?utm_source=zero.xyzWhen to prefer
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.
Side effects
- 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
