SignalHarness Crosschain Transaction Normalizer
x402
SignalHarness Crosschain Transaction Normalizer is a paid API for AI agents from signalharness.ai, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-15).
Normalizes and unifies transaction records across multiple blockchain networks (Solana, Base, Polygon) into a consistent format from caller-supplied data

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 normalized transaction records with chain labels, original IDs, sequential indices, and supply status for each record. Also includes a list of any unsupported fields per transaction, the set of chains processed, warnings (e.g. that the service does not fetch or authenticate transactions), and an evidence_scope indicating that results are based purely on caller-supplied data.
Example use cases
Multi-chain portfolio reconciliation
“I have transaction records from three different chains — Solana, Base, and Polygon — and I need them all normalized into one consistent structure so I can reconcile my portfolio. Here's the raw JSON with the transaction IDs and chain metadata, can you standardize them?”
Cross-chain analytics pipeline prep
“Before feeding these transactions into my analytics dashboard, I need to normalize them across Solana, Base, and Polygon into a unified format. Here's the transaction JSON — flag any fields that aren't supported in the common schema.”
DeFi audit trail unification
“I'm auditing DeFi activity across multiple chains and I have a mixed batch of transactions from Base, Polygon, and Solana that all use different field formats. Can you normalize this JSON into a consistent crosschain record structure and let me know if anything couldn't be mapped?”
Technical details
Endpoint
POSThttps://signalharness.ai/api/agent/services/crosschain_transaction_normalize/invokeWhen to prefer
Choose this endpoint when you have raw transaction records from multiple blockchain networks (Solana, Base, Polygon) that need to be unified into a single consistent schema for downstream analytics, auditing, or display. It is best suited for agent pipelines that have already retrieved transaction data and need normalization without on-chain lookups. Avoid it if you need live transaction fetching, authentication, or validation against actual chain state.
Side effects
- Invalid or malformed request_json returns an error — input must be valid JSON string
- Unsupported blockchain networks not in {solana, base, polygon} may result in unrecognized chain warnings or omitted records
- Fields present in source transactions but not mappable to the common schema are listed under unsupported_fields rather than silently dropped
- Service does not fetch or validate transactions on-chain — results depend entirely on the accuracy of caller-supplied data
- Oversized inputs exceeding 65536 characters will be rejected
