How this service works
Micropay research APIs (x402 v2 + bazaar). Free catalog at /.well-known/x402.json. Primary v2 accepts: Base eip155:8453 only. Legacy X-PAYMENT-TX still supports bsc|base via acceptsV1. Headers: X-PAYMENT-TX, X-PAYMENT-NETWORK, PAYMENT-SIGNATURE. No financial advice.
Output
A JSON object with an 'ok' boolean, a 'meta' object containing the token's symbol (e.g. 'USDC') and decimals (e.g. 18), and a 'product' field identifying the endpoint type as 'token_meta'.
Example use cases
Validate token before DeFi swap
“Before I execute this swap, can you confirm the symbol and decimals for the token at 0xdAC17F958D2ee523a2206206994597C13D831ec7 on BSC so I know I'm working with the right asset?”
Enrich transaction history display
“I have a list of token contract addresses on Base — can you fetch the symbol and decimals for 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 so I can label it properly in my portfolio dashboard?”
Decode raw on-chain transfer amount
“I see a raw token transfer of 1000000 units from a contract at 0x2791Bca1f2de4661ED88A30C99A7a9449Aa84174 on BSC — what are its decimals so I can convert that to a human-readable amount?”
Technical details
Endpoint
GEThttps://desk-x402.desk-x402-gh.workers.dev/v1/token-metaWhen to prefer
Use this endpoint when you need fast, on-chain ERC-20 token metadata (symbol and decimals) for a specific contract address on BSC or Base, especially in micropayment-native agent workflows using x402. Prefer it over manual RPC calls when you want a simple REST interface without setting up a full blockchain node client.
Side effects
- Invalid or malformed contract address (not a valid 0x hex address) — likely returns an error or empty meta
- Unsupported network (only 'bsc' and 'base' are accepted) — request will be rejected
- Contract address exists but is not an ERC-20 token — metadata may be missing or incomplete
- Payment not provided or invalid x402 payment headers — returns HTTP 402 Payment Required
- Rate limiting or worker unavailability — returns 5xx error
