Xerxes Base Transaction Status Checker is a paid API for AI agents from ari001.tailb4ac3a.ts.net, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-14).
Checks whether a Base blockchain transaction has landed, returning its status (pending, confirmed, reverted, not_found, or unread) along with confirmation count, decoded USDC Transfer logs, and a proof-stamped head block reference.

How this service works
Use when an agent needs to know whether a Base transaction landed. Returns pending, reverted, confirmed with confirmations, not_found, or unread. Decodes USDC Transfer logs. Proof-stamped with the head block. Missing value is null, not zero.
Output
Returns a status field (pending, confirmed, reverted, not_found, or unread), a confirmation count when confirmed, decoded USDC Transfer log entries if present, and a proof stamp containing the current head block number. Missing numeric values are returned as null rather than zero.
Example use cases
Post-payment confirmation check
“I just sent a USDC payment on Base with hash 0xabc123...def456 — can you tell me if it confirmed and whether the USDC transfer event was decoded successfully?”
Revert diagnosis for failed tx
“My Base transaction 0x9f8e7d...1234ab shows as failed in my wallet — can you check if it was reverted and give me the details?”
Webhook trigger readiness check
“Before I trigger my fulfillment webhook, can you verify that Base transaction 0x5c6d7e...890fab has at least 6 confirmations and isn't still pending?”
Technical details
Endpoint
GEThttps://ari001.tailb4ac3a.ts.net/v1/base/tx/:hashWhen to prefer
Use this endpoint when you specifically need to verify the landing status of a Base (Ethereum L2) transaction by hash, especially when you also need decoded USDC Transfer event data and a cryptographic head-block proof stamp. Prefer this over generic Ethereum RPC calls when you need a single structured response covering status, confirmations, and token transfer decoding together, and when operating in an x402 payment-aware agent context on Base.
Side effects
- Transaction hash not found on Base — returns not_found status
- Transaction submitted but not yet indexed — returns pending or unread
- Invalid or malformed transaction hash format — likely 4xx error
- Network or node unavailability — may return an error or timeout
- Transaction exists but has no USDC logs — logs field returns empty or null
