# Mycelia Signal Cross-Asset Divergence Oracle

> Mycelia Signal Cross-Asset Divergence Oracle is a paid API for AI agents from api.myceliasignal.com, paid per call via x402, $0.5/call, status unknown (last checked 2026-09-13).

Detects and quantifies disagreement between crypto and traditional finance market regimes, returning a signed divergence level with direction, signals, and contagion flag.

## Facts

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 mycelia-signal-cross-asset-divergence-oracle-a72a69f1
```

Example prompt: What's the current divergence level between crypto and traditional finance markets — are they in agreement or pulling apart, and is there any contagion risk I should know about?

## When to prefer this

Choose this endpoint when you need a high-level, cryptographically verifiable assessment of whether crypto markets and traditional finance are aligned or diverging — particularly useful for risk management, portfolio hedging signals, or macro regime monitoring. Prefer this over raw price feeds when you need a synthesized, pre-classified regime-level signal rather than raw price data, and when auditability via Ed25519 attestation matters.

## Known failure modes

- Payment not included or insufficient — HTTP 402 returned requiring x402 payment of 0.5 USDC
- Service unavailable or upstream market data feed outage — HTTP 503
- Rate limit exceeded — HTTP 429
- Signature verification failure on client side if Ed25519 public key is misconfigured

## How this service works

Cross-Asset Divergence — detects disagreement between crypto and TradFi regimes. NONE/LOW/MODERATE/HIGH/EXTREME with direction, signals, contagion flag. Layer 3 Oracle Intelligence. — Ed25519 signed attestation

## Output

Returns a structured, Ed25519-signed attestation containing a divergence severity classification (NONE, LOW, MODERATE, HIGH, or EXTREME), the direction of divergence, underlying market signals driving the assessment, and a boolean contagion flag indicating whether regime disagreement is spreading across asset classes.
