# 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 by identifier, proxying the DefiLlama price feed via a pay-per-call gateway.

## 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-368abc63
```

Example prompt: What are the current prices of Bitcoin and Ethereum right now? Look them up using coingecko:bitcoin and coingecko:ethereum identifiers.

## When to prefer this

Use this endpoint when you need real-time token price data for one or multiple cryptocurrencies identified by CoinGecko slug or on-chain contract address, and you want a pay-per-call model settled in USDC with no API key required. Prefer this over direct DefiLlama API calls when operating in an x402-compatible agent environment on Base.

## Known failure modes

- Invalid or unrecognized coin identifier returns empty or error response
- Malformed comma-separated list may cause partial results
- Payment not settled (402) blocks the request
- Rate limiting if too many coins or calls in rapid succession
- Token contract address on wrong chain returns no 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

Returns current price data for the requested coins, keyed by their coin identifiers (e.g. coingecko:bitcoin), including USD price values sourced from the DefiLlama price feed.
