## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability wafermap-xyz-glm-5-3-63c52bef -d '<json body>'
```

Example prompt: Use GLM 5.3 to write me a careful, step-by-step project plan for launching a SaaS product — including market research, MVP scoping, go-to-market strategy, and a 90-day timeline, keeping the output under 1500 tokens.

## When to prefer this

Choose this endpoint when the task requires deliberate, careful prose or multi-step planning rather than quick Q&A — GLM 5.3 is positioned as a frontier model for structured reasoning and writing quality. Prefer it over DeepSeek Flash or Llama Scout when accuracy of reasoning and writing polish matter more than raw speed. Use DeepSeek Pro instead if the task is heavy math or code; use GLM 5.3 for nuanced writing, planning, and structured analysis.

## Known failure modes

- Prompt exceeds 24,000 character limit — request rejected
- max_tokens set to 0 or negative — validation error
- System instructions exceed 8,000 characters — request rejected
- Model output truncated if max_tokens is set too low for the task
- Payment of 0.01725 USDC not fulfilled — 402 error returned
- Network timeout on longer generation tasks
