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 containing a wallet_period_comparison string summarizing the differences between the two periods, a list of warnings about anomalies or issues detected, an evidence_scope field indicating the data source ('caller_supplied_data'), and a full receipt with payment details, execution metadata, latency, and a SHA-256 result hash for verification.
Example use cases
Monthly wallet behavior review
“Compare my wallet activity from last month versus this month and highlight any major changes in how I've been using it on-chain.”
Pre/post DeFi strategy comparison
“I changed my DeFi strategy in March — can you compare my wallet's activity from February to April so I can see if it actually made a difference?”
Quarterly portfolio activity audit
“Run a period comparison on my wallet for Q1 versus Q2 this year — I want to see the differences in transaction patterns and get any warnings about unusual behavior.”
Technical details
Endpoint
POSThttps://signalharness.ai/api/agent/services/wallet_period_compare/invokeWhen to prefer
Choose this endpoint when you need a structured, agent-native comparison of blockchain wallet activity across two distinct time windows — particularly when you want warnings surfaced automatically and a verifiable receipt. Prefer this over generic blockchain explorers when you need programmatic, LLM-friendly output with evidence scope metadata rather than raw transaction dumps.
Side effects
- Malformed or missing wallet_period_request input returns a validation error
- Insufficient wallet data for one or both periods may produce incomplete comparisons
- Ambiguous period definitions in the request string may lead to misinterpreted date ranges
- Payment failure on-chain results in a failed status receipt without executing the comparison
- Very large request strings near the 65536 character limit may cause processing delays or truncation
