# 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 for one or more coins using DeFiLlama identifiers (CoinGecko slugs or EVM contract addresses)

## 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-be48c199
```

Example prompt: What are the current prices of dYdX and GMX tokens? Use the DeFiLlama price feed via BlockRun — the coin IDs are coingecko:dydx-chain and coingecko:gmx.

## When to prefer this

Use this endpoint when you need current token prices for one or more cryptocurrencies using DeFiLlama-style identifiers (CoinGecko slugs or on-chain contract addresses), especially in DeFi or on-chain analytics contexts. Prefer this over CoinGecko or CoinMarketCap direct APIs when you want pay-per-call access with no API key, settled in USDC on Base. Ideal for batch price fetching of DeFi-native tokens like GMX, dYdX, or arbitrary EVM tokens by contract address.

## Known failure modes

- Unknown or misspelled coin identifier returns no price data for that coin
- Invalid format (missing chain prefix like 'coingecko:') may cause lookup failure
- Rate limiting or payment failure ($0.001 USDC per call via x402) blocks the request
- Network or upstream DeFiLlama outage returns error or stale data
- EVM contract address on wrong chain returns no result

## 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 map of coin identifiers to their current USD prices, sourced from DeFiLlama's price aggregation layer. Each entry includes the token's price and likely metadata such as timestamp or confidence.
