## 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 drug-product-data-sourcing-and-paid-search-decision-procedure-6ea83ecb
```

Example prompt: Give me the decision procedure for sourcing drug product data and running paid searches — I need a plain-prose guide my autonomous agent can follow when it needs to find pharmaceutical product information.

## When to prefer this

Choose this endpoint when an autonomous AI agent needs a ready-made, prose-form decision procedure for drug product data sourcing and paid search, rather than building its own logic. Ideal for agents that need structured guidance on pharmaceutical data workflows without hardcoding domain knowledge. Preferred over generic LLM queries because it is purpose-built, priced per-call at $0.002 USDC, and returns a consistently structured response with source attribution.

## Known failure modes

- HTTP 402 returned if payment has not been settled — agent must pay exact USDC amount and retry with PAYMENT-SIGNATURE header
- Invalid or missing input parameters return validation errors
- LLM generation failure may result in ok:false in the result object
- Network timeout if the Base blockchain payment confirmation is slow
- Requesting meta=1 returns free metadata instead of the paid decision procedure

## How this service works

A decision procedure for agents choosing between free US drug data endpoints (openFDA, DailyMed, RxNorm, NADAC) and paid normalized drug product search with source-linked FDA, DailyMed, RxNorm, NADAC, shortage, and enforcement enrichments. Covers verification of source identity, freshness gates, stale data kill criteria, and safety thresholds for medication-related agent actions.

## Output

A JSON object containing a plain-prose decision procedure brief (120+ words) tailored for AI agents, including the topic, model used, generation source (llm, reasoning, or deterministic), ISO-8601 timestamp, and service slug. The 'brief' and 'procedure' fields contain the actionable guidance text.
