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 JSON object with a 'wallet_gas_spend' result string, a list of warnings, an evidence scope label ('caller_supplied_data'), a status field ('succeeded'), and a full receipt including payment ID, network (Base/eip155:8453), service version, latency, and a SHA-256 hash of the result for verification.
Example use cases
DeFi wallet gas cost audit
“I want to audit how much gas my DeFi wallet has been burning — can you run a gas spend analysis on this wallet data: '0xDeFiWallet123...gasQuery' and flag any warnings?”
Agent treasury gas monitoring
“My AI agent has been running transactions all week — can you compute the gas spend from this usage data: '0xAgentTreasury456...gasReport' so I can see if we're over budget?”
Gas optimization before deployment
“Before I deploy my next batch of smart contract calls, can you check this wallet's gas spend record — '0xDevWallet789...gasSummary' — and tell me if there are any concerns I should know about?”
Technical details
Endpoint
POSThttps://signalharness.ai/api/agent/services/wallet_gas_spend/invokeWhen to prefer
Choose this endpoint when you need on-demand, per-call gas spend analysis for a wallet and want a lightweight, pay-per-use model ($0.01 USDC) with a cryptographic receipt. Prefer this over blockchain explorer APIs when you want structured output with warnings and evidence scope rather than raw transaction data.
Side effects
- Input string too short (below minLength:2) returns validation error
- Input string exceeds 65536 characters causing rejection
- Malformed or unparseable gas request string returns empty or error result
- Payment failure via x402 protocol blocks invocation
- Network or service unavailability returns non-succeeded status
