# BlockRun Token Price Lookup (DefiLlama)

> BlockRun Token Price Lookup (DefiLlama) is a paid API for AI agents from blockrun.ai, paid per call via x402, $0.002/call, status unknown (last checked 2026-09-14).

Fetches current token prices by coin identifier (CoinGecko slug or EVM contract address) using DefiLlama price feeds, supporting comma-separated multi-token lookups.

## 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-token-price-lookup-defillama-9f89f353
```

Example prompt: What are the current prices of staked Ether and wrapped Bitcoin? Use the DefiLlama price feed with coingecko:staked-ether and coingecko:wrapped-bitcoin.

## When to prefer this

Use this endpoint when you need real-time token prices for one or more crypto assets identified by CoinGecko slug or EVM contract address, especially in a DeFi or on-chain analytics context. It supports batch lookups in a single call, making it efficient for portfolio pricing. Prefer over generic crypto APIs when you specifically need DefiLlama-sourced prices with no API key and pay-per-call USDC settlement.

## Known failure modes

- Invalid coin identifier format returns an error or empty result
- Unknown or unsupported token identifier yields no price data
- Network or upstream DefiLlama feed unavailability causes service errors
- Malformed comma-separated list may result in partial or failed responses
- Payment not settled (402) if x402 micropayment not included

## 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

Returns a JSON object containing current USD prices for each requested token, keyed by coin identifier (e.g. coingecko:staked-ether → price in USD).
