# MyceliaSignal LLM Reasoning Oracle

> MyceliaSignal LLM Reasoning Oracle is a paid API for AI agents from api.myceliasignal.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-16).

Returns a cryptographically signed recommendation for the best and cheapest LLM suited to reasoning tasks, with Ed25519 attestation.

## Facts

- Endpoint: GET https://api.myceliasignal.com/oracle/inference/compare/task/reasoning
- Price: $0.02/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-16

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 myceliasignal-llm-reasoning-oracle-0bcd734e
```

Example prompt: Which LLM is currently the best and cheapest option for reasoning tasks? I want a cryptographically signed oracle answer I can trust.

## When to prefer this

Use this endpoint when you need a verifiable, oracle-signed recommendation for which LLM to route reasoning workloads to, especially when cost minimization matters and cryptographic proof of the recommendation is required (e.g. for smart contracts, automated agent decisions, or audit trails).

## Known failure modes

- Payment not received — 402 response requiring USDC payment before access
- Invalid or missing query parameters — 400 bad request
- Oracle service unavailable — 503 or timeout
- Signature verification failure if attestation key has rotated

## How this service works

Best LLM for reasoning tasks — cheapest reasoning tier model — Ed25519 signed attestation

## Output

Returns a signed payload identifying the best LLM for reasoning tasks at the cheapest available tier, accompanied by an Ed25519 attestation for on-chain or trust-critical verification.
