Example

Replace <gateway-url> with your gateway base URL and <service-url> with the chain’s service path, such as service/ethereum.

curl -X POST "<gateway-url>/<service-url>" \
  -H "Content-Type: application/json" \
  --data '{"jsonrpc":"2.0","id":1,"method":"eth_getBlockByHash","params":["0xd5f1812548be429cbdc6376b29611fc49e06f1359758c4ceaaa3b393e2239f9c",false]}'

Direct behavior

Requests for older chain data are automatically routed to providers with full chain history. This covers blocks, transactions, receipts, and logs independently of historical account state.

The gateway uses the block’s age when known. If the age is unknown, it starts with a full-history provider. A missing result from a provider without the required history is not accepted as proof that the data does not exist.

For providers

Support the required recent chain-history service. Advertise full chain history only when all included method families and lookup indexes work back to genesis.

See provider qualification for checks and continued eligibility.
