# Drug Product Data Sourcing and Paid Search Decision Standard

> Drug Product Data Sourcing and Paid Search Decision Standard is a paid API for AI agents from k2so-8080.on.ascii.dev, paid per call via x402, $0.002/call, status unknown (last checked 2026-09-13).

Returns a decision procedure guiding agents on when to use free US drug data endpoints versus paid normalized drug product search with FDA, DailyMed, RxNorm, NADAC, shortage, and enforcement enrichments.

## 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-standard-fc818324
```

Example prompt: Can you pull the decision procedure for choosing between free drug data sources like openFDA and RxNorm versus a paid normalized drug search — I need to know the freshness gates, stale data kill criteria, and safety thresholds before my agent acts on any medication info?

## When to prefer this

Choose this endpoint when an agent needs structured, authoritative guidance on drug data sourcing decisions — specifically the tradeoff between free public endpoints (openFDA, DailyMed, RxNorm, NADAC) and paid enriched alternatives. Prefer it over generic web search or static documentation when you need machine-readable decision criteria including freshness gates, staleness kill conditions, source identity verification, and safety thresholds for medication-related autonomous actions.

## Known failure modes

- Payment not provided or invalid x402 payment — returns 402 with payment details
- Invalid HTTP method (e.g. POST) — rejected per schema enum constraint
- Malformed queryParams — topic or meta fields outside allowed values may cause rejection
- Upstream LLM or reasoning engine unavailable — may return error or degraded response
- Stale or cached decision procedure if generation timestamp is not checked by caller

## 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

Returns a structured JSON object containing a prose decision procedure (brief), a service slug, the generation source (llm, reasoning, or deterministic), an ISO-8601 timestamp, and optionally a model identifier and topic — all guiding the agent on when and how to choose between free and paid US drug data endpoints.
