## 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 chiro-x402-chiropractic-knowledge-retrieval-speaking-74c8eb03 -d '<json body>'
```

Example prompt: Search the chiropractic knowledge base for speaking scripts and talking points on how to explain spinal decompression to a new patient — I need clear, patient-friendly language a chiropractor could use in a consultation.

## When to prefer this

Choose this endpoint when an AI agent or chiropractic professional needs to retrieve vetted, domain-specific chiropractic speaking content — patient communication language, clinical explanation scripts, or presentation talking points — and can pay $0.05 USDC per query via x402 without needing API keys or account setup. Prefer over general-purpose search when chiropractic-specific vocabulary, clinical accuracy, and structured knowledge segments are required.

## Known failure modes

- Insufficient or invalid x402 payment token returns 402 Payment Required
- Query too vague returns low-relevance or empty knowledge segments
- Network mismatch (not Base mainnet) causes payment rejection
- Malformed payment object causes 400 Bad Request
- No segments matching the query topic returns empty results
- Service downtime returns 5xx errors

## How this service works

Paid AI-agent endpoint for searching 500K+ segments of general chiropractic knowledge. $0.05 USDC per query on Base mainnet. No API keys, no accounts — agents pay via x402 v2 protocol and receive structured results.

**Corpus:** Clinical protocols, wellness plans, marketing strategies, patient communication, practice management — sourced from general chiropractic training.

## Output

Structured results containing relevant chiropractic knowledge segments — likely including text excerpts from clinical protocols, wellness plan language, patient communication scripts, or practice management guidance related to speaking and verbal presentation, ranked or filtered by relevance to the query.
