# BlockRun.AI Token Price Lookup (DefiLlama)

> BlockRun.AI 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-style coin identifiers (e.g. coingecko:bitcoin or ethereum:0x...).

## Facts

## 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-token-price-lookup-defillama-82c177a4
```

Example prompt: What are the current prices of Bittensor and Artificial Superintelligence Alliance — look them up via coingecko identifiers coingecko:bittensor and coingecko:artificial-superintelligence-alliance.

## When to prefer this

Use this endpoint when you need real-time token price data for one or more cryptocurrencies identified by CoinGecko slugs or on-chain contract addresses, especially in a pay-per-call context without needing a persistent API key. Prefer this over alternatives when working in a Web3/agent context that already handles x402 micropayments.

## Known failure modes

- Invalid or unrecognized coin identifier returns an error or missing entry in the response
- Comma-separated list with a malformed identifier may cause partial or full failure
- Network or upstream DefiLlama API outage returns a 5xx error
- Payment failure (x402) if USDC balance is insufficient

## 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 coin identifier, keyed by the coin identifier string (e.g. coingecko:bitcoin -> price value).
