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 an analysis_json field with diagnostics about the submitted trace, a list of warnings (e.g. data verification advisories), an evidence_scope indicator (e.g. 'caller_supplied_data'), a replay flag, the service_id, and a full execution receipt with payment metadata, latency, request/execution IDs, and a result SHA-256 hash.
Example use cases
Debugging repeated agent task failures
“My agent keeps retrying the same step and I don't know why — can you analyze this execution trace JSON and tell me what's going wrong and what warnings showed up?”
Post-mortem on failed agent workflow
“We had an agent workflow crash last night — here's the full trace JSON from the run. Can you analyze it and tell me where it failed and what the root cause looks like?”
Validating agent trace before production deploy
“Before I push this agent to production, can you run this trace JSON through the retry analyzer and flag any warnings or suspicious retry patterns I should address first?”
Technical details
Endpoint
POSThttps://signalharness.ai/api/agent/services/agent_trace_retry_analyze/invokeWhen to prefer
Choose this endpoint when you have a raw agent execution trace or retry log in JSON format and need automated diagnostic analysis — particularly when debugging why an agent repeatedly failed or retried a step. It is purpose-built for agent observability use cases on the SignalHarness platform, priced at $0.01 USDC per call via x402, making it cost-effective for frequent debugging cycles.
Side effects
- Malformed or non-JSON request_json input returns a validation error
- request_json exceeding 65,536 characters is rejected
- Empty or too-short input (minLength:2) is rejected
- Payment failure on the x402 protocol results in no execution
- Ambiguous or incomplete trace data may yield low-confidence analysis with generic warnings
