How this service works
ARYSPHERE Base typed objects and transaction proofs behind x402. Dead RPC is unreadability, not zeros.
Output
A JSON object with ok status, sender and recipient addresses, transaction kind (confirmed/pending/reverted), a proof object containing block hash and block number, transaction hash, log count, value in wei, total confirmations, and an array of USDC transfer events each with to/from addresses and atomic amount.
Example use cases
Verify USDC payment settlement
“I just sent a USDC payment on Base — the tx hash is 0xabcd1234...ef56. Can you confirm it landed and tell me how many confirmations it has?”
Audit on-chain transfer for support ticket
“A customer claims they paid us on Base with tx hash 0x7890abcd...1234. Can you pull up the transaction and verify who sent it, who received it, and how much USDC moved?”
Check pending transaction before releasing goods
“Before I release this order, I need to know if Base tx 0xdeadbeef...cafe is fully confirmed or still pending — can you check the confirmation count and block number?”
Technical details
Endpoint
GEThttps://ari001.tailb4ac3a.ts.net/v1/base/tx/%7Bhash%7DWhen to prefer
Use this endpoint when you specifically need typed proof of a Base chain transaction — confirmation status, block anchoring, and decoded USDC transfer events in a single call. Prefer it over raw RPC when you need structured, agent-readable output without parsing raw EVM logs. Best suited for x402 payment verification workflows where you need to confirm a USDC payment settled on Base before taking a downstream action.
Side effects
- Transaction hash not found — returns error or ok:false
- Transaction is still pending — kind field will reflect pending state rather than confirmed
- Malformed or invalid hash format — likely 4xx error
- RPC backend unreachable — service-level error
- Hash belongs to a chain other than Base — incorrect or empty result
