# ChainRay Gas Average Oracle

> ChainRay Gas Average Oracle is a paid API for AI agents from chainray.online, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-15).

Returns the average gas fee for a specified blockchain network in real-time

## Facts

- Endpoint: GET https://chainray.online/oracle/gas-avg
- Price: $0.005/call
- Payment: x402
- Status: unknown

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 chainray-gas-average-oracle-800dbdc3
```

Example prompt: What's the current average gas fee on Ethereum right now? I want to know if it's a good time to submit a transaction.

## When to prefer this

Use this endpoint when an AI agent needs to check current average gas fees on a specific blockchain before submitting a transaction, estimating costs, or advising a user on timing. Prefer this over manual RPC calls when you need a normalized, multi-chain gas oracle with pay-per-request pricing and no subscription overhead.

## Known failure modes

- Unsupported chain identifier returns an error or empty result
- Missing chain parameter may default to a single chain or return an error
- Payment of $0.005 USDC not received results in HTTP 402 rejection
- Network downtime or RPC issues may cause stale or unavailable gas data
- Invalid chain string returns a validation error

## How this service works

The most complete blockchain data and intelligence service for AI agents. 93 endpoints across 46 chains, from gas fees to DeFi analytics, with real-time streams, intent routing, and verifiable proofs. Pay-per-request via x402.

## Output

Returns the average gas price for the requested blockchain network, likely including values in Gwei or native units, along with the chain identifier and timestamp of the measurement.
