       I would like to build high quality OCaml bindings to the Zulip REST API,

     

       2
       +
       documented at https://zulip.com/api/rest.  As another reference, the Python

     

       3
       +
       `zulip` library from pip is well maintained.

     

       4
       +
       

     

       5
       +
       My target is to use the OCaml EIO direct-style library, with an idiomatic as

     

       6
       +
       possible API that implements it. For JSON parsing, using the jsonm library is

     

       7
       +
       right. For HTTPS, use cohttp-eio with the tls-eio library.

       ## Overview

     

       18
       +
       The library follows OCaml best practices with abstract types (`type t`) per module, comprehensive constructors/accessors, and proper pretty printers. Each core concept gets its own module with a clean interface.

       ## Key EIO Advantages

     

       422
       +
       

     

       423
       +
       1. **Structured Concurrency**: Each bot runs in its own fiber with proper cleanup

     

       424
       +
       2. **Resource Safety**: Automatic cleanup of connections, event queues, and HTTP servers

     

       425
       +
       3. **Backpressure**: Natural flow control through EIO's cooperative scheduling

     

       426
       +
       4. **Error Isolation**: Bot failures don't crash the entire server

     

       427
       +
       5. **Graceful Shutdown**: Structured teardown of all resources

     

       428
       +
       

     

       429
       +
       ## Design Principles

     

       430
       +
       

     

       431
       +
       1. **Abstract Types**: Each major concept has its own module with abstract `type t`

     

       432
       +
       2. **Constructors**: Clear `create` functions with optional parameters

     

       433
       +
       3. **Accessors**: All fields accessible via dedicated functions

     

       434
       +
       4. **Pretty Printing**: Every type has a `pp` function for debugging

     

       435
       +
       5. **JSON Conversion**: Bidirectional JSON conversion where appropriate

     

       436
       +
       6. **Error Handling**: Consistent `(_, Error.t) result` return types

     

       437
       +
       

     

       438
       +
       ## Authentication Strategy

     

       439
       +
       

     

       440
       +
       - Support zuliprc files and direct credential passing

     

       441
       +
       - Abstract `Auth.t` prevents credential leakage

     

       442
       +
       - HTTP Basic Auth with proper encoding

     

       443
       +
       

     

       444
       +
       ## EIO Integration

     

       445
       +
       

     

       446
       +
       - All operations use EIO's direct-style async

     

       447
       +
       - Resource-safe client management with `with_client`

     

       448
       +
       - Proper cleanup of connections and event queues

     

       449
       +
       

     

       450
       +

       This design is based on comprehensive analysis of:

     

       525
       +
       

     

       526
       +
       1. **Zulip REST API Documentation**:

     

       527

          - Main API: https://zulip.com/api/rest

     

       528
       +
          - Error Handling: https://zulip.com/api/rest-error-handling  

     

       529
       +
          - Send Message: https://zulip.com/api/send-message

     

       530
       +
       

     

       531
       +
       2. **Python Zulip Library**:

     

       532
       +
          - Main repository: https://github.com/zulip/python-zulip-api

       +
          - Bot framework: https://github.com/zulip/python-zulip-api/blob/main/zulip_bots/zulip_bots/lib.py

     

       534
       +
          - Bot server: https://github.com/zulip/python-zulip-api/blob/main/zulip_botserver/zulip_botserver/server.py

     

       535
       +
       

     

       536
       +
       The design adapts these Python patterns to idiomatic OCaml with abstract types, proper error handling, and EIO's structured concurrency for robust, type-safe Zulip integration.
