How this service works
Stable edge-hosted x402 utilities for autonomous agents.
Output
Returns a JSON object containing the token balance (as a string integer), the metadata URI (e.g. ipfs://...), and the network name (e.g. 'polygon') for the queried wallet, contract, and token ID combination.
Example use cases
NFT gate ownership verification
“Does wallet 0xDEF...456 own at least one of ERC-1155 token ID 7 from contract 0xABC...123 on Polygon? I need to decide whether to grant them access.”
Game item inventory check
“How many of game item token ID 99 (contract 0x111...AAA) does player wallet 0x222...BBB hold on Polygon right now?”
Fetch NFT metadata for display
“Pull the metadata URI for ERC-1155 token ID 5 from contract 0x333...CCC on Polygon so I can display the artwork and attributes for wallet 0x444...DDD.”
Technical details
Endpoint
GEThttps://free-asset-radar-x402.besenok2018.workers.dev/api/x402/erc1155-balance?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, pay-per-call ERC-1155 balance and metadata URI lookup without managing your own blockchain RPC infrastructure. It is ideal for autonomous agents that need on-demand multi-token balance checks on networks like Polygon, especially when integrated into x402 payment flows.
Side effects
- Invalid or malformed wallet/contract address returns an error
- Unsupported network identifier returns a lookup failure
- Token ID not found in contract returns zero balance or error
- Network RPC unavailability causes timeout or 5xx response
- Missing required parameters (address, tokenId, contract) results in 400 Bad Request
