## 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 per-use-research-acquisition-decision-procedure-465c4b94
```

Example prompt: Should I buy access to this premium financial research report on emerging market bonds — run a full decision check covering whether it's relevant to my current task, whether the price is worth the expected insight, how fresh the content is, and what my redistribution rights would be.

## When to prefer this

Choose this endpoint when an autonomous agent needs a structured, multi-factor decision framework before committing a micro-payment for premium financial research — specifically when task relevance, price justification, content freshness, licensing rights, and provider legitimacy all need to be evaluated together. Prefer this over ad-hoc agent reasoning when a defensible, auditable purchase trail is required for post-settlement reconstruction or compliance purposes.

## Known failure modes

- Payment not received — returns 402 with payment instructions
- Invalid or missing input parameters — returns error with validation detail
- Topic parameter unrecognized or too vague — procedure may return generic guidance rather than targeted assessment
- Provider legitimacy data unavailable — procedure may flag inconclusive verdict
- LLM generation failure — fallback to deterministic or reasoning-based response
- Rate limiting or service unavailability on k2so-8080.on.ascii.dev

## How this service works

A decision procedure for autonomous agents evaluating per-use access to premium financial research content via MPP/x402 micro-payments. Covers a task relevance gate, price versus expected insight value assessment, freshness and recency checks, licensing and redistribution boundaries including cache, citation and resale rights, research spend budget accounting, provider legitimacy verification, and a full purchase audit trail suitable for post-settlement reconstruction.

## Output

A structured JSON response containing a prose decision procedure brief for the agent, covering task relevance, price-vs-insight-value verdict, freshness/recency assessment, licensing and redistribution boundaries (cache, citation, resale), research budget accounting status, provider legitimacy signals, and a purchase audit trail. Also includes metadata such as generation model, topic, service slug, ISO-8601 timestamp, and generation source (llm/reasoning/deterministic).
