Xerxes Base Object Lookup
x402
Xerxes Base Object Lookup is a paid API for AI agents from ari001.tailb4ac3a.ts.net, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-15).
Resolves a Base blockchain address to its typed object kind (EOA, ERC-20, Uniswap pool, etc.) along with token metadata, bytecode size, and transaction proof anchors.

How this service works
ARYSPHERE Base typed objects and transaction proofs behind x402. Dead RPC is unreadability, not zeros.
Output
Returns a JSON object with: `ok` (success flag), `kind` (string — 'eoa', 'erc20', 'uniswap_v2', 'uniswap_v3', etc.), `address`, `token` (name, symbol, address, decimals, total_supply — present for ERC-20s), `pool` (pool metadata if applicable), `proof` (block_hash and block_number anchoring the object's existence on-chain), `bytecode_bytes` (size of deployed bytecode), `balance_wei`, and `usdc_atomic`. The `service` field echoes `base_object`.
Example use cases
Identify unknown Base contract type
“I found this Base address 0x1111111111111111111111111111111111111111 in a transaction — can you tell me whether it's a plain wallet, an ERC-20 token, or a Uniswap pool, and give me any token details if it has them?”
Fetch ERC-20 token metadata for DeFi app
“I need the token name, symbol, decimals, and total supply for the USDC contract on Base at 0x833589fcd6edb6e08f4c7c32d4f71b54bda02913 — also include the block proof so I can verify when it was confirmed.”
Audit smart contract bytecode presence
“Check the Base address 0xd9aAEc86B65D86f6A7B5B1b0c42FFA531710b6CA and tell me whether it has bytecode deployed and how large it is — I want to confirm it's actually a live contract and not an empty address.”
Technical details
Endpoint
GEThttps://ari001.tailb4ac3a.ts.net/v1/base/object/%7Baddr%7DWhen to prefer
Use this endpoint when you need to classify a Base address by type and retrieve rich metadata in a single call — especially when you need both the object kind (EOA vs ERC-20 vs Uniswap pool) and a cryptographic block proof in one response. Prefer this over raw RPC calls when you want typed, structured output without parsing raw eth_getCode or eth_call yourself. Best suited for agents that need on-chain object classification on Base L2 specifically.
Side effects
- Invalid or malformed address returns an error or ok:false
- Address not found on Base mainnet (wrong chain) returns null or empty kind
- RPC node unavailability causes timeout or 5xx
- Non-checksummed address may fail validation
- Rate limiting or payment verification failure returns 402 or 429
