# GENESIS Agent Tools — Verify Crypto Price Consensus

> GENESIS Agent Tools — Verify Crypto Price Consensus is a paid API for AI agents from genesis-agent-tools.genesisagenttools.workers.dev, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-01).

Aggregates and cross-validates cryptocurrency price data from multiple sources to produce a consensus price for a given token, with optional deep-tier evidence collection.

## 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 genesis-agent-tools-verify-crypto-price-consensus-3a1b815e -d '<json body>'
```

Example prompt: Can you verify the price consensus for ETH on Base using a quick-tier check — I want to make sure the price I'm seeing is accurate and consistent across sources?

## When to prefer this

Choose this endpoint when you need a verified, multi-source consensus price for a cryptocurrency token — especially before executing trades, swaps, or DeFi actions where price accuracy matters. It is particularly useful when you have a contract address and need to confirm it corresponds to a legitimate asset with a real market price. Prefer the 'deep' tier when you need evidence trails or are auditing a suspicious token; use 'quick' for fast pre-flight checks.

## Known failure modes

- Unknown or unrecognized token symbol returns empty result or warning
- Invalid contract address causes lookup failure or null result
- Unsupported chain returns an error or empty evidence
- Insufficient data sources produce low-confidence consensus or warnings array populated
- Payment not processed (x402) results in 402 Payment Required error
- Network timeout from upstream price sources causes delayed or partial response

## How this service works

Pay-per-call x402 APIs for autonomous agents on Base USDC: API compatibility analysis, bounded HTTP/JSON workflows, URL evidence analysis, crypto price consensus, and agent/MCP readiness checks.

## Output

Returns a JSON object with a boolean 'ok' status, the tier used ('quick' or 'deep'), a 'result' object containing consensus price data, a 'product' classification (e.g. 'asset-intelligence'), an 'evidence' array listing supporting sources, and a 'warnings' array flagging any anomalies or inconsistencies detected.
