# MyceliaSignal LLM Long-Context Task Benchmark Oracle

> MyceliaSignal LLM Long-Context Task Benchmark Oracle is a paid API for AI agents from api.myceliasignal.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-14).

Returns a cryptographically signed attestation identifying the best LLM for long-context tasks based on the largest context window, with Ed25519 signature.

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-long-context-task-benchmark-oracle-196974e7
```

Example prompt: Which LLM currently has the largest context window for long-context tasks? Give me a cryptographically signed answer I can trust.

## When to prefer this

Use this endpoint when you need a verifiable, cryptographically attested recommendation for which LLM offers the largest context window — particularly useful in smart contract, DeFi, or oracle-driven workflows where tamper-proof provenance of model selection decisions matters.

## Known failure modes

- Payment not received — returns 402 Payment Required
- Invalid request format — returns 400 Bad Request
- Upstream model data unavailable — returns 503
- Ed25519 signing service failure — attestation cannot be generated

## How this service works

Best LLM for long-context tasks — largest context window — Ed25519 signed attestation

## Output

A signed oracle response identifying the best LLM for long-context tasks, including the model name, context window size, and an Ed25519 cryptographic signature attesting to the result's authenticity.
