Technical details
Endpoint
POSThttps://bb-crypto.vercel.app/api/gas/recommendationWhen to prefer
Use this endpoint when you need real-time gas fee recommendations for EVM-compatible chains and want tiered suggestions (slow/standard/fast) to help users optimize transaction costs. Prefer this over manual RPC calls when you need a curated, monetized recommendation rather than raw fee history data.
Side effects
- Network unavailable — upstream RPC node unreachable, returns 5xx error
- Invalid network specified — returns 400 with unsupported chain message
- Payment not received — returns 402 Payment Required if x402 payment header missing or invalid
- Rate limit exceeded — too many requests in a short window
