# Edge Agents Signal Decay & Model Drift Monitor

> Edge Agents Signal Decay & Model Drift Monitor is a paid API for AI agents from pay.edge-agents.ai, paid per call via x402, $0.25/call, status unknown (last checked 2026-09-14).

Returns an evidence-backed assessment of signal decay and model drift across cross-market data sources, flagging whether intelligence signals remain fresh and reliable.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability edge-agents-signal-decay-model-drift-monitor-1b10e84c
```

Example prompt: Can you pull the latest Signal Decay & Model Drift Monitor report from Edge Agents and tell me whether current cross-market signals are still fresh and high-confidence, or if there's been drift I should know about?

## When to prefer this

Choose this endpoint when you need an evidence-backed, point-in-time assessment of whether cross-market signals have decayed or drifted, with signed provenance and explicit confidence ratings — particularly useful for AI agent pipelines that must validate input signal quality before making decisions, or for compliance and audit scenarios requiring documented source freshness.

## Known failure modes

- Payment not received or insufficient USDC balance — 402 Payment Required response
- Invalid or malformed request parameters — 400 Bad Request
- Service temporarily unavailable or upstream data source outage — 503
- Report data incomplete or stale sources — dataStatus field may reflect partial coverage
- Signed provenance check fails if issuer certificate has changed

## How this service works

Signal Decay & Model Drift Monitor. Evaluates the quality, disagreement, transmission, composition or verification of Edge intelligence itself. Purpose: Increase the defensibility of downstream decisions by making evidence quality and model limitations machine-readable. 5-minute freshness target; missing evidence is reported explicitly rather than invented.

## Output

A JSON object containing a quality block (status and confidence level), an analysis block (market family, intent tags, and narrative summary of drift findings), an evidence block (assets list, policy, and sources), provenance details (issuer URL and signature status), a generatedAt timestamp, a dataStatus field, schema version, and a disclaimer noting this is impersonal market research and not investment advice.
