# MycелiaSignal SOL/USD Basis and Carry Oracle

> MycелiaSignal SOL/USD Basis and Carry 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 the current SOL/USD basis and carry metrics as an Ed25519-signed cryptographic attestation

## 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 myc-iasignal-sol-usd-basis-and-carry-oracle-0a74ca48
```

Example prompt: What's the current SOL/USD basis and carry right now — and can you get me a cryptographically signed attestation I can verify on-chain?

## When to prefer this

Use this endpoint when you need a tamper-evident, cryptographically verifiable SOL/USD basis and carry figure — particularly for DeFi protocols, smart contract inputs, or any workflow where you need to prove the data has not been altered in transit. Prefer this over raw exchange feeds when on-chain verifiability or audit trails are required.

## Known failure modes

- Service unavailable or rate-limited returning 4xx/5xx HTTP errors
- Payment not processed correctly via x402 protocol resulting in 402 Payment Required
- Stale data if underlying market feeds are temporarily unavailable
- Invalid or expired Ed25519 signature if keys have rotated
- Network timeout during real-time fetch

## How this service works

Solana spot-futures basis and annualized carry — cross-venue arbitrage signal for basis traders — Ed25519 signed attestation

## Output

A signed payload containing the current SOL/USD basis spread and carry rate, accompanied by an Ed25519 cryptographic signature that allows downstream consumers to verify authenticity and integrity of the oracle data without trusting the transport layer.
