How to call any catalog model through the API
Use the OpenAI-compatible AshnaAI API to call any catalog model: get a key, list ids from GET /v1/api/models, then POST /v1/api/chat/completions with that id in the model field. The same route works for GLM-5.3-Flash, GPT-5.6 Terra, Claude rows, Kimi K3, or a custom agent id.
AshnaAI
One API, any catalog id
Developers calling models through AshnaAI use an OpenAI-compatible HTTP API. Base URL: https://api.ashna.ai/v1/api Auth is Authorization: Bearer YOUR_API_KEY. The model field is either a foundation catalog id or a custom agent id. That is how GLM-5.3-Flash, GPT-5.6 Terra, a Claude row, Kimi K3, or Ashna-X1 are called from code—one route, not a URL per vendor.
Official reference: AshnaAI API docs, including model and agent ids. If you do not have a key, apply for API access.
Step 1: Get a key
Request access at apply-api. After you can sign in, open Account → API and create a key. Send it as a Bearer token. Do not put the key in a public blog, client bundle, or screenshot.
Step 2: List models, then pick an id
GET https://api.ashna.ai/v1/api/models returns the OpenAI list shape. Copy the id string exactly as listed—for Flash that is glm-5.3-flash. The same id is visible in the in-app model picker. Custom agents use the agent id on the same chat-completions path. Endpoint notes: list models.
Step 3: POST chat completions
POST https://api.ashna.ai/v1/api/chat/completions with model, messages, and optional stream, temperature, or max_tokens. To switch from Flash to GPT-5.6 Terra, change model to gpt-5.6-terra. To run a saved agent, pass that agent’s customAgentId as model. Endpoint notes: chat completions.
To try Flash in the product UI instead of curl, open GLM-5.3-Flash in chat. For when to pin Flash versus other rows, start at Pin GLM-5.3-Flash for cost-effective coding.

Apply at www.ashna.ai/apply-api, create a key in Account → API, then open AshnaAI API docs and run the chat-completions examples with the model id you listed.
Frequently asked questions
- How do I call GLM-5.3-Flash through the AshnaAI API?
- Create a Bearer key, then POST https://api.ashna.ai/v1/api/chat/completions with model set to glm-5.3-flash and a messages array. To try it in the product first, open the pinned chat link.
- Does every catalog model use the same API route?
- Yes. List ids with GET /v1/api/models, then POST /v1/api/chat/completions. Only the model field changes. Custom agents use the same POST path with the agent id.
- Where do I apply for API access?
- Use https://www.ashna.ai/apply-api After approval, create a key at https://app.ashna.ai/account?tab=api
- Is this OpenAI-compatible?
- Yes. Use the same clients and auth style. Set base URL to https://api.ashna.ai/v1/api Full reference is on the AshnaAI API docs.
- How do custom agents use this API?
- GET /v1/api/models returns foundation models. A custom agent uses the same chat-completions path: pass the agent’s customAgentId as model, or send agent_id when model is omitted.
