# 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 (e.g. coingecko:bitcoin or Ethereum contract addresses), settled via x402 micropayment.

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-token-price-lookup-defillama-46bf5502
```

Example prompt: What are the current prices of Wormhole and Celestia? Use their coingecko identifiers: coingecko:wormhole and coingecko:celestia.

## When to prefer this

Use this endpoint when you need fast, pay-per-call token price lookups using DefiLlama-backed data without setting up an API key. Ideal for multi-token price checks using coingecko slugs or ERC-20 contract addresses, especially in agentic workflows on Base where USDC micropayments are available. Prefer over direct DefiLlama API when operating in an x402-enabled environment.

## Known failure modes

- Invalid coin identifier format returns an error or empty result
- Unknown coingecko slug or contract address returns no price data
- Payment of 0.001 USDC required per call — missing or failed x402 payment returns 402 Payment Required
- Network latency or DefiLlama upstream outage may cause timeouts
- Comma-separated list with one invalid identifier may cause partial or full failure

## 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 coin identifiers, sourced from DefiLlama. Includes USD price values for each requested token, keyed by the coin identifier string provided.
