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 the computed ranking diff, a warnings array advising verification of caller-supplied data, an evidence_scope field indicating the data source, the service_id, and a full payment receipt with execution metadata including latency, payment ID, and result hash.
Example use cases
SEO ranking change audit
“I have two sets of keyword ranking data from my site — one from Monday and one from today. Can you diff them and tell me which keywords moved up or down in search position?”
Before/after campaign ranking comparison
“We just launched a content campaign last week. Can you compare my pre-campaign and post-campaign search ranking snapshots and show me the differences in keyword positions?”
Competitor ranking shift detection
“I pulled search ranking data for my competitors before and after the latest Google algorithm update. Can you analyze the diff and tell me which positions shifted the most?”
Technical details
Endpoint
POSThttps://signalharness.ai/api/agent/services/search_ranking_diff/invokeWhen to prefer
Choose this endpoint when you need a lightweight, pay-per-call computation of differences between two sets of search ranking data without maintaining a persistent SEO tool subscription. Best suited for agent workflows that periodically compare ranking snapshots and need structured JSON output with an auditable payment receipt. Prefer this over full SEO platform integrations when cost predictability ($0.01 per call) and agent-native x402 payment compatibility are priorities.
Side effects
- Malformed or invalid request_json input returns a schema validation error
- Caller-supplied data that does not conform to expected ranking structure may produce unreliable or empty analysis
- Service unavailability on the Base network may cause payment to succeed but execution to fail
- Empty or minimal JSON input (under 2 characters) is rejected at schema level
- Result warnings are always present reminding callers to verify caller-supplied data before relying on output
