How this service works
List supported RPC chains and methods.
Output
An array of supported blockchain chains, each with their chain identifiers and the RPC methods available for that chain on the Spraay gateway.
Example use cases
Example prompt
“What blockchain networks and RPC methods are supported on the Spraay gateway? I want to know which chains I can route RPC calls through.”
Technical details
Endpoint
GEThttps://gateway.spraay.app/api/v1/rpc/chainsWhen to prefer
Use this endpoint when you need to discover which blockchain networks and RPC methods are available before routing RPC calls through the Spraay gateway. Prefer this over hardcoding chain lists or using other RPC discovery mechanisms when already integrated with Spraay's x402-based gateway.
Side effects
- Payment failure (402): x402 micropayment not attached or insufficient; returns 402 status
- Gateway unavailable (503): upstream infrastructure down
- Empty chains array: no chains currently configured or enabled
