# Solenrich Perps Basis Signal

> Solenrich Perps Basis Signal is a paid API for AI agents from api.solenrich.com, paid per call via x402, $0.015/call, status unknown (last checked 2026-09-14).

Computes perpetual mark vs spot price across venues (Hyperliquid, dYdX, Jupiter, Adrena) and surfaces funding-rate arbitrage opportunities with APR above a configurable threshold.

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 solenrich-perps-basis-signal-111d0407 -d '<json body>'
```

Example prompt: Can you scan SOL for perp basis trade opportunities right now — I only want to see venues where the funding APR is actually earnable (like Hyperliquid or dYdX), and filter to anything above 8% APR?

## When to prefer this

Use this endpoint when you need to identify cross-venue perpetual funding rate arbitrage or basis trade opportunities for SOL, BTC, ETH, or BONK — especially when you want to distinguish actually-earnable yield (order-book perps like Hyperliquid/dYdX) from pool-based perps where funding cannot be captured. Prefer this over generic funding rate lookups when you want filtered, threshold-gated, actionable trade signals with per-venue economics in one call.

## Known failure modes

- Unsupported asset symbol returns validation error
- min_yield_apr_pct out of range (0-100) returns 400
- No opportunities above threshold returns empty opportunity list
- Venue data unavailable at call time may return stale or partial results
- Payment failure returns 402 before computation begins

## How this service works

Computes perp mark vs spot price across venues and surfaces actually-earnable yield (funding APR on Hyperliquid + dYdX, not viable on pool perps Jupiter + Adrena). Returns per-venue trade economics, opportunities above threshold, and best trade. Threshold defaults to 5% APR.

## Output

Returns per-venue trade economics including funding APR, mark vs spot spread, and trade viability flags; a filtered list of opportunities above the APR threshold; and a highlighted best trade recommendation. Venues are annotated for whether funding yield is actually earnable (Hyperliquid and dYdX) vs not viable (pool perps like Jupiter and Adrena).
