Example prompt: What are the top 25 crypto market sectors right now, ranked by total value locked?

## When to prefer this

Use this endpoint when you need a ranked overview of crypto market sectors or categories by TVL, rather than data on a specific token or protocol. Ideal for market research, portfolio allocation, trend analysis, or building dashboards that require a high-level segmentation of the crypto ecosystem. Prefer this over individual token price or protocol TVL endpoints when the goal is sector-level aggregation and ranking.

## Known failure modes

- limit out of range (must be 1–100) returns validation error
- payment failure via x402 protocol returns 402 error
- upstream data provider unavailable returns 503 or timeout
- no categories found returns empty list

## How this service works

Crypto categories & sectors ranked by total value locked (USD): each DeFi narrative (e.g. Dexes, Lending, Liquid Staking, Restaking, RWA) with its aggregate TVL, protocol count and share of total DeFi TVL. A map of where capital sits across sectors. Centralised-exchange reserves are excluded.

## Output

A ranked list of cryptocurrency market categories and sectors, ordered by total value locked (TVL), up to the requested limit (default 15, max 100). Each entry likely includes the category/sector name, TVL figure, and associated ranking metadata.
