Endpoint
POSThttps://prysm-kappa.vercel.app/api/v1/providers/gnewsWhen to prefer
Choose this endpoint when you need to fetch or search news articles using the GNews API but want to pay per call in USDC via x402 on Base mainnet without managing a separate GNews API key. Ideal for agents that need lightweight, pay-as-you-go news search in crypto-native workflows.
Side effects
- Invalid or missing operation name returns an error indicating the operation is not allowlisted
- Malformed input object may result in a provider-side error or empty results
- Payment failure over x402 prevents the request from being processed
- GNews API quota exhaustion or downtime causes upstream errors
- Overly broad queries may return irrelevant or low-quality articles
