# RagRadar Gas Price Lookup by Chain

> RagRadar Gas Price Lookup by Chain is a paid API for AI agents from backup.ragradar.space, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-13).

Fetches current on-chain gas prices for a specified blockchain network (Base, Arbitrum, Solana, etc.)

## Facts

- Endpoint: GET https://backup.ragradar.space/api/gas/%7Bchain%7D
- Price: $0.001/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-13

- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_g3gdvO2V2Ww8w17O88nvz

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 ragradar-gas-price-lookup-by-chain-13851f7a
```

Example prompt: What's the current gas price on Base right now? I want to know if it's a good time to send a transaction.

## When to prefer this

Use this endpoint when an AI agent needs real-time gas price data for Base, Arbitrum, or Solana to help users time transactions, estimate costs, or automate gas-sensitive workflows. Prefer over general blockchain explorers when low-latency, pay-per-call pricing via x402 micropayments is acceptable and cross-chain coverage in one API is needed.

## Known failure modes

- Unsupported chain identifier returns an error or empty response
- Network congestion or node unavailability may return stale or missing data
- Malformed chain parameter causes a bad request error
- Payment not fulfilled via x402 micropayment results in 402 response blocking data access

## How this service works

On-chain intelligence for AI agents. 73+ endpoints across Base, Arbitrum, Solana. x402 micropayments.

## Output

Returns a JSON object with status and current gas price data for the specified blockchain chain, including fee estimates useful for timing transactions.
