# MyeliaSignal H200 Best Price Oracle

> MyeliaSignal H200 Best Price Oracle is a paid API for AI agents from api.myceliasignal.com, paid per call via x402, $0.05/call, status unknown (last checked 2026-09-14).

Returns the best current H200 GPU rental price across all cloud/compute providers, with an Ed25519 signed attestation for verifiability.

## Facts

- Price: $0.05/call
- Payment: x402
- Status: unknown

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 myeliasignal-h200-best-price-oracle-c9703f8b
```

Example prompt: What's the best H200 GPU price available right now across all providers? I need a signed attestation I can trust.

## When to prefer this

Use this endpoint when you need a single, trusted, cryptographically verifiable price point for H200 GPU compute — especially in automated agent workflows where attestation integrity matters or where you need to compare H200 pricing specifically (not L40S, RTX 4090, or other GPU tiers). Prefer this over manual scraping or unauthenticated price feeds when auditability is required.

## Known failure modes

- No price data available if all upstream sources are unreachable
- Stale price data if providers have not updated recently
- Invalid or unverifiable Ed25519 signature if attestation fails
- Payment failure (402) if USDC payment of $0.05 is not included
- Rate limiting if too many requests are made in quick succession

## How this service works

Cheapest H200 GPU rental — best hourly rate across cloud providers for large model inference — Ed25519 signed attestation

## Output

Returns the lowest available H200 GPU price found across all aggregated compute sources, along with which provider is offering it, a timestamp, and an Ed25519 cryptographic signature attesting to the authenticity of the price data.
