# CoinOpSelect Compute Arbitrage API

> CoinOpSelect Compute Arbitrage API is a paid API for AI agents from coinop.publicvm.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-21).

Compares compute resource pricing across cloud providers (e.g. Akash, Render) to identify the cheapest option for a given tier and duration, paid per call via x402 on Base.

## 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 coinopselect-compute-arbitrage-api-edde32e3 -d '<json body>'
```

Example prompt: Compare compute pricing for 1 medium-tier instance for 2 hours across Akash and Render — which provider is cheapest right now?

## When to prefer this

Use this endpoint when you need real-time, on-demand compute price arbitrage data across decentralized and traditional cloud providers (Akash, Render) and want to pay only per call via x402 on Base without a subscription. Prefer this over manual price checking when building autonomous agents that need to programmatically select the cheapest compute provider for a given workload tier and duration.

## Known failure modes

- Invalid or unsupported provider name returns empty or error result
- Missing required quotes array causes request failure
- Payment not fulfilled via x402 results in 402 Payment Required response
- Unsupported compute tier returns no matching results
- Network or provider API unavailability may return empty result object

## How this service works

Paid on-chain token, wallet, contract and research data over x402 on Base.

## Output

Returns a JSON object with a query identifier ('compute-arbitrage') and a result object containing the price comparison data across the specified providers, tiers, and durations, enabling identification of the lowest-cost compute option.
