CREC API Go

Go client, server stubs, and shared models for the CREC (CRE Connect) API. Generated from OpenAPI specifications.

Overview

This repository provides:

• client — HTTP client for calling CREC API endpoints (channels, watchers, wallets, operations, events)
• models — Shared types such as VerifiableEvent, EVMEvent, Channel, Wallet, and operation/event types
• ginserver / stdserver — Generated server stubs for implementing the API (Gin or net/http)

Installation

go get github.com/smartcontractkit/crec-api-go/client
go get github.com/smartcontractkit/crec-api-go/models

Usage

Client

import (
    "context"
    "log"
    "github.com/smartcontractkit/crec-api-go/client"
)

func main() {
    c, err := client.NewClient("https://api.example.com")
    if err != nil {
        log.Fatal(err)
    }

    channels, err := c.GetChannels(context.Background(), nil)
    if err != nil {
        log.Fatal(err)
    }
    // Use channels...
}

Use client.WithRequestEditorFn to add auth headers (e.g. API key) to requests.

Models

The models package is used by crec-workflow-utils, crec-sdk-ext-dta, crec-sdk-ext-dvp, and other CREC components for VerifiableEvent, EVMEvent, and related types.

Regenerating Bindings

After modifying api/openapi.yaml or models/models.yaml:

make tools && make generate

This runs oapi-codegen for the client, server stubs, and models.

Validating the OpenAPI Spec

make validate-openapi
