What it does

This x402-gated endpoint from Erudite Intelligence LLC returns gas price information for specified tokens and blockchain networks. You POST a JSON body containing a token address (or the zero address for the native token) and a chain identifier (e.g. "base", "ethereum", "tron"), and receive gas price data in response.

The endpoint accepts payment via x402 v2 on two networks: USDC on Base (eip155:8453) at 10,000 base units ($0.01) per call, or USDT on Tron (tron:728126428) at 10,000 base units ($0.01) per call. The facilitator is Coinbase CDP's x402 endpoint. The provider describes the endpoint's category as "Crypto data intelligence."

The parent service, EruditePay Bridge, is an x402 payment facilitator supporting 20 blockchains. It is operated by Erudite Intelligence LLC, a FinCEN-registered MSB (BSA ID 31000324258137). The Bridge itself provides verify/settle endpoints for x402 payment flows, while this specific endpoint (/v1/base/gas/price) serves crypto data rather than payment facilitation. Documentation at docs.eruditepay.com is referenced but the /docs path on the bridge returns a 404, so detailed API docs for this endpoint are not available.

The endpoint is live (402 challenge captured) with a clear input schema and pricing, but the output schema example is a stub ({"success": true, "data": {}}), no detailed docs are available (docs path returns 404), and the actual response structure is unknown. The description 'Crypto data intelligence' is vague.

Warnings

  • —Output example in the bazaar schema is a stub with an empty data object — actual response fields are unknown.
  • —docs.eruditepay.com is referenced but /docs on the bridge returns 404; no detailed API documentation was found.
  • —The endpoint description 'Crypto data intelligence' is generic and does not specifically confirm gas-price functionality beyond the URL path.
