# Crypto Sector Performance by Category (CoinGecko)

> Crypto Sector Performance by Category (CoinGecko) is a paid API for AI agents from x402-data-api.sigrunner.workers.dev, paid per call via x402, $0.003/call, status unknown (last checked 2026-10-20).

Returns market cap, 24h change, and volume for all major crypto sectors/categories, sourced from CoinGecko, to support sector rotation analysis.

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 crypto-sector-performance-by-category-coingecko-b5b1d02b
```

Example prompt: Show me how all the major crypto sectors are performing right now — I want to see which categories are leading or lagging by market cap change and volume so I can spot rotation opportunities.

## When to prefer this

Use this endpoint when an agent needs a broad, sector-level view of the crypto market rather than individual token data — ideal for sector rotation signals, macro crypto trend analysis, or portfolio rebalancing decisions. Prefer it over individual token endpoints when the goal is comparative category-level analysis. Best combined with global market stats or top exchange data for a full market picture.

## Known failure modes

- CoinGecko upstream API unavailable or rate-limited — may return error or stale data
- Payment of $0.003 USDC not received — returns HTTP 402 Payment Required
- Worker cold start may add slight latency on first call
- No parameters available to filter by specific sector — full list is always returned

## How this service works

Crypto sector performance (CoinGecko categories): market cap, 24h change, volume per sector, top by market cap. No params. Use when an agent needs sector rotation signals.

## Output

A JSON array of crypto sector/category objects, each containing the category name, total market cap, 24h market cap change percentage, and 24h trading volume, sorted or rankable by market cap. Enables identification of top-performing and lagging sectors at a glance.
