14EVM chains with live gas data

A drop-in replacement for the Blocknative gas API

If you called Blocknative's /gasprices/blockprices, change the host and keep the code. Same response format, same confidenceLevels parameter, no API key.

curl "https://logicnodes.io/gasprices/blockprices?chainid=8453"

What you get beyond the old API: 14 chains, an honest 503 when data is stale instead of an old number, a public status page, and change notices before anything about the API changes. Existing responses are not changing.

For agents

{ "mcpServers": { "logicnodes": { "url": "https://logicnodes.io/mcp" } } }

81 verified read-only tools for EVM and Aptos (Aptos guide): ambiguous input is refused with every option listed, amounts are exact, every answer states its source and ledger version. Connect to https://logicnodes.io/mcp/v2 for all of them.
