The client defaults to https://api.reactor.network; its default reusable http.Client has a 30-second timeout. Send accepts a context, generates a secure request ID unless RequestID is set, and calculates the payload hash from decoded bytes.

EVM package


chainPayload, err := evm.EncodeChainMessage(evm.ChainMessageRequest{
    Payload: "0x010203",
    Parameters: []evm.Parameter{{Name: "destination", Value: "base"}},
})
chainRequest, err := evm.DecodeChainMessage(chainPayload)


webPayload, err := evm.EncodeWebMessageRequest(evm.WebMessageRequest{
    Method: "POST",
    URL: "https://example.com/v1",
    Body: `{"ping":"pong"}`,
    Headers: []evm.Parameter{{Name: "accept", Value: "application/json"}},
})
webRequest, err := evm.DecodeWebMessageRequest(webPayload)
webResponse, err := evm.DecodeWebMessageResponse(responsePayload)


randomRequest, err := evm.DecodeGenerateRandomNumbersRequest(payload)
numbers, err := evm.DecodeGenerateRandomNumbersResponse(responsePayload) // []*big.Int

The helper package preserves full uint256 range with *big.Int and returns 0x ABI bytes ready for Client.Send.

API failures can be matched with errors.As to *reactor.APIError, which includes StatusCode, Code, Detail, and RetryAfter. Supply a custom reusable HTTPClient through ClientOptions when needed.

See the HTTP API for wire behavior and statuses.
