How this service works
Explore 330 pay-per-call x402 API services and 27 agent-native digital products, with Base USDC pricing, secure Polar checkout, and free discovery.
Output
Returns a structured analysis JSON containing: list of transfers with from/to addresses, token IDs, amounts, operator, and log index; duplicate position flags; total units transferred; network context including accepted chain IDs, deposit transaction type, fee model, and protocol family (OP Stack); evidence scope (caller_supplied_data); analyzed network (Base); and warnings about proof limitations.
Example use cases
Audit NFT transfer for gaming item
“I have an ERC-1155 transfer JSON from Base mainnet for a gaming item transfer — can you parse it and tell me the token ID, how many units moved, who sent it, and who received it?”
Detect duplicate token positions in batch transfer
“Can you analyze this ERC-1155 batch transfer JSON from Base and flag any duplicate token positions — I want to make sure there are no redundant entries before I process it downstream?”
Inspect multi-token DeFi transfer details
“Here's an ERC-1155 transfer log from a Base chain DeFi protocol — please decode it and give me a full breakdown including operator, token ID, amounts, and the OP Stack fee model context.”
Technical details
Endpoint
POSThttps://signalharness.ai/api/agent/services/base_erc1155_transfer_analyze/invokeWhen to prefer
Choose this endpoint when you need fast, structured parsing of ERC-1155 token transfer data specifically on the Base (OP Stack) network, especially to extract transfer participants, token IDs, amounts, and detect duplicate positions. Prefer it over generic blockchain explorers when you need programmatic JSON output suitable for downstream agent processing, and when you don't need on-chain balance verification.
Side effects
- Malformed or invalid JSON in request_json field returns an error
- Missing required transfer fields cause incomplete analysis
- Token balance and receipt authenticity are not verified — only structural analysis
- Chain IDs outside Base mainnet (8453) or Base Sepolia (84532) may not be recognized
- Oversized input exceeding 65536 characters is rejected
