> Technical Design Supplied-Term Coverage is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-18).

Scans a technical design document and identifies where supplied terms appear, producing a bounded term-coverage deliverable.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 technical-design-supplied-term-coverage-5410c478 -d '<json body>'
```

Example prompt: Check this technical design document for the terms 'authentication', 'latency', and 'caching' — I need to know where each one appears across the Architecture, Interfaces, and Trade-offs sections.

## When to prefer this

Choose this endpoint when you need a deterministic, non-generative check of whether specific terms appear in a technical design document. It is ideal for compliance checks, terminology audits, or pre-review scans where you want exact matching rather than AI-generated analysis or summaries. It is not suitable if you need prose generation, semantic similarity matching, or fact-checking.

## Known failure modes

- Text exceeds 20,000 character limit — request rejected
- Terms array is empty or contains more than 20 items — validation error
- Term string exceeds 80 characters — rejected at schema level
- Malformed input JSON — 400 error
- Payment not included or insufficient — 402 payment required
