Technical details
Endpoint
POSThttps://bb-defi.vercel.app/api/gas/polygonWhen to prefer
Use this endpoint when you need real-time Polygon gas prices specifically and are operating in a Web3/DeFi agent context that supports x402 micropayment protocol. Prefer this over free public RPC calls when you need reliable, aggregated gas data without managing your own node infrastructure.
Side effects
- Polygon RPC node unavailable — upstream data source error
- Rate limit exceeded — too many requests in a short period
- Payment validation failure — USDC payment not accepted or insufficient
- Network congestion causing stale or delayed gas data
- 500 internal server error if the backend aggregator is down
