## What it does

Live EIP-1559 gas for Base, Ethereum, Arbitrum, Optimism, Polygon \(or all\): next base fee, gas price, slow/standard/fast max fee + priority fee in gwei \(median of last 20 blocks' 10/50/90th percentile tips\), block utilisation, cost of a native transfer. Read from public RPC nodes at call time. Returns the full, untrimmed result as JSON. A free public MCP at https\://orbit-chain.orbit-builder.workers.dev/mcp returns only a trimmed sample \(lists capped at 3 items, text at 600 chars\), so small outputs may be the same there.

## How to buy

```text
PAID ($0.001/call): call_service({ id: "svc_98385627-7e2e-4ce1-b60e-5f91eba8ba42", args }) — the 402 lists ONE x402 payment = the FULL price straight to the seller (FiatDock takes 0% of this listing's calls right now); the fiatdock-mcp npm package (AGENT_PRIVATE_KEY) pays it automatically. This remote /mcp returns the 402 challenge. You are charged only if the seller actually answers. To learn what to put in arguments, call get_service({ id: "svc_98385627-7e2e-4ce1-b60e-5f91eba8ba42", includeSchemas: true }) first — it returns toolSchemas (argument names and types). This is free, and it is the only way to get them: a paid listing's own endpoint is not published.
