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 blockrun-ai-defillama-token-price-lookup-a74251fd
```

Example prompt: What are the current prices for The Sandbox (SAND) and Decentraland (MANA)? Use their CoinGecko IDs coingecko:the-sandbox and coingecko:decentraland.

## When to prefer this

Use this endpoint when you need current spot prices for one or more crypto tokens identified by CoinGecko slug or on-chain EVM contract address, especially when you want DeFiLlama's aggregated price feed. Prefer this over raw exchange APIs when you need cross-venue price consensus or need to look up DeFi/metaverse tokens not always available on CEX APIs. Ideal for batch lookups of multiple tokens in a single call.

## Known failure modes

- Invalid or unrecognized coin identifier returns empty or null price entry
- Malformed coin namespace (e.g. wrong chain prefix) causes missing data
- Rate limiting or payment failure (x402) blocks the request
- Comma-separated list parsing errors if identifiers contain unexpected characters
- Token not indexed by DeFiLlama returns no price data

## How this service works

Token price lookup. Pass coin identifiers as `/v1/defillama/prices/{coins}` (e.g. `coingecko:bitcoin`, `ethereum:0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2`). Supports comma-separated lists.

## Output

A map of coin identifiers to their current USD prices, returned as a JSON object keyed by the coin identifier strings that were passed in (e.g. coingecko:the-sandbox, coingecko:decentraland).
