AEML Gauge Calibrated Unit Plug-in
x402
AEML Gauge Calibrated Unit Plug-in is a paid API for AI agents from aeml-x402.zeabur.app, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-13).
Returns cross-site-comparable calibrated unit projections (normalized_index / pct_to_action) for a given signal and entity, or 422 with no-charge flag if no calibration exists for that signal line.

How this service works
Add-on, calibrated units: normalized_index and pct_to_action so readings compare across stations. When the line has no calibration basis you get 422 with no_charge:true and reason:no-calibrated-for-this-line, and are NOT billed. Every record carries an offline-recomputable record_hash.
Output
Returns a JSON object with a 'calibrated' sub-object containing normalized_index and pct_to_action (cross-site comparable values), plus metadata fields: signal_id, entity, entity_name, observed_at, grade (data quality tier), scope statement, nature (neutrality disclaimer), provenance (freshness, data lineage, data age), record_hash, and optional _citation for offline verification. If no calibration exists for the requested signal line, returns HTTP 422 with no_charge:true and reason:no-calibrated-for-this-line — meaning the call is not billed.
Example use cases
Normalized crypto signal comparison
“Get me the calibrated gauge reading for the crypto.spot signal on BTC — I need the normalized_index and pct_to_action so I can compare it cross-site with other signal sources.”
Macro unemployment signal calibration check
“What's the calibrated unit projection for the macro.unemployment signal for the US entity? I want to see the normalized_index and whether it's near the action threshold.”
Shipping route disruption gauge reading
“Pull the calibrated normalized index for the shipping.route-disruption signal on the Hormuz entity — include the provenance freshness status and grade so I know how decision-ready the data is.”
Technical details
Endpoint
GEThttps://aeml-x402.zeabur.app/gauge/calibratedWhen to prefer
Choose this endpoint when you need cross-site-comparable normalized signal readings (normalized_index / pct_to_action) for a specific signal-entity pair, especially when you want to benchmark or compare gauge readings across different sources or time periods on a standardized scale. Prefer this over the full /gauge endpoint when you only need the calibrated projection and want to minimize cost ($0.02 vs fuller bundles). If the line has no calibration, you are not charged. Use /gauge/catalog or /gauge/preview (free) first to confirm the signal_id and entity are valid before calling.
Side effects
- 422 with no_charge:true and reason:no-calibrated-for-this-line — signal line has no calibrated unit defined; call is not billed
- Missing or invalid signal_id parameter — malformed dot-notation label
- Missing or invalid entity parameter — entity not recognized in catalog
- Payment failure via x402 protocol — USDC payment not accepted
- Stale data indicated by freshness:stale in provenance — data may not reflect current conditions
- null calibrated field — calibration data temporarily unavailable despite line existing
