x402
x402 Bazaar Rank – Token Contract Lookup is a paid API for AI agents from x402-bazaar-rank.x402-bazaar-rank-worker.workers.dev, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-18).
Resolves an EVM token contract address on Base to its on-chain metadata (name, symbol, decimals) via live eth_call reads.

How this service works
Ranked discovery over the live x402 service market: every indexed service scored by real 30-day calls and paying-wallet bounds, with a receipt naming the snapshot hash and scoring revision.
Output
Returns a JSON object with the token's on-chain name, symbol, and decimals; boolean checks for whether the contract responds to name() and version() calls; the network identifier (eip155:8453 for Base); the queried contract address; the read method used (eth_call); a disclaimer about endorsement; and a generatedAt timestamp.
Example use cases
Identify unknown token contract
“I found this contract address on Base — 0xd9aAEc86B65D86f6A7B5B1b0c42FFA531710b6CA — can you tell me what token it is, its symbol, and how many decimals it uses?”
Verify USDC contract compliance
“Can you confirm that 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base actually responds to ERC-20 name and version calls so I know it's a legitimate USDC contract?”
Fetch token decimals for payment logic
“I need the decimals for the token at 0x50c5725949A6F0c72E6C4a641F24049A917DB0Cb on Base so I can figure out the correct payment amount scaling.”
Technical details
Endpoint
GEThttps://x402-bazaar-rank.x402-bazaar-rank-worker.workers.dev/tokenWhen to prefer
Use this endpoint when you need live, trustless on-chain token metadata from the Base network specifically, rather than relying on a curated token list that may be stale or incomplete. Ideal when you have a raw contract address and need to confirm it is a legitimate ERC-20 and retrieve its symbol/decimals for payment calculations or display purposes.
Side effects
- Contract address not found or not deployed on Base — returns empty or error response
- Address is not an ERC-20 token contract — name()/symbol()/decimals() calls may fail or return empty
- Invalid address format (non-hex, wrong length) — likely returns a 400 or schema validation error
- Network congestion on Base causing read latency or timeout
- Payment not included or invalid — 402 response blocking access
