# AgentOracle Asset Assessment

> AgentOracle Asset Assessment is a paid API for AI agents from aiagentoracle.ai, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-13).

Evaluates an asset's market-data quality, freshness, liquidity, volatility, confidence score, and x402/Base spendability before an autonomous transaction.

## 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 agentoracle-asset-assessment-cfb1707f
```

Example prompt: Before you execute that payment, can you assess the market-data quality, freshness, and spendability of ETH on Base — specifically whether it's safe to spend directly via x402 or if I need to convert it first?

## When to prefer this

Use this endpoint immediately before any autonomous transaction or payment involving a crypto asset, especially on Base via x402. Prefer it when you need a holistic pre-flight check combining data freshness, liquidity depth, volatility, confidence scoring, and spendability classification in a single call — rather than querying spot price, volume, and chain support separately.

## Known failure modes

- Unknown or unsupported ticker symbol returns quality: insufficient-data with null price and confidence
- Stale data source returns freshness.status: stale with elevated ageSeconds
- Low liquidity assets return spendability: unsupported or convert-first
- Market data gaps return marketSignals.completeness: sparse or partial
- Invalid symbol format may return 4xx error
- Payment failure (USDC balance insufficient) returns 402

## How this service works

AgentOracle: use before an autonomous transaction to assess an asset's market-data quality, freshness, liquidity, volatility, confidence, and whether it is directly spendable through x402 on Base or must be converted first. Informational and non-custodial.

## Output

Returns a structured assessment object including: quality rating (high/medium/low/insufficient-data), current USD price, confidence score (0–1), freshness metadata (timestamp, age in seconds, fresh/stale status), market signals (liquidity USD, 24h volume, market cap, 24h volatility percent, completeness rating), spendability classification (direct-spend/convert-first/unsupported/insufficient-data), human-readable rationale strings, and a list of limitations.
