## 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 merchant-side-adoption-decision-procedure-for-card-network-backed-b9b17243
```

Example prompt: I'm a mid-size e-commerce merchant trying to decide whether to adopt Visa or Mastercard crypto settlement versus sticking with x402 rails — give me a blunt decision procedure covering fees, settlement speed, chargeback coverage, integration cost, and counterparty risk.

## When to prefer this

Choose this endpoint when a merchant-side agent needs a structured, opinionated decision framework — not marketing material — for choosing between card-network-backed crypto settlement (Visa, Mastercard, Google, Stripe) and x402 or legacy card rails. Particularly useful when fee economics, chargeback liability, and integration cost all need to be weighed simultaneously in a single callable brief. Prefer over general financial research tools when the specific domain is crypto settlement rail selection for merchants.

## Known failure modes

- Payment not confirmed — returns 402 requiring USDC micropayment before content is delivered
- Invalid query parameter values (e.g. meta enum not '0' or '1') may cause schema validation errors
- LLM generation failure — ok:false in result with no brief returned
- Stale or hallucinated analysis if underlying model knowledge is outdated on rapidly evolving card-network crypto standards
- Topic override may return off-scope content if query is too broad or unrelated to merchant settlement

## How this service works

Paid agent-facing brief on merchant-side adoption decision procedure for card-network-backed crypto settlement standards (Visa/Mastercard/Google/Stripe backed standard vs existing x402 and card rails): fee economics, settlement rails, dispute/chargeback coverage, integration cost, counterparty scope. Blunt decision procedure, not marketing.

## Output

A structured prose brief containing a blunt decision procedure for merchants, covering: fee economics across settlement rails, settlement speed comparison, dispute and chargeback coverage differences, integration cost estimates, and counterparty scope — generated by an LLM/reasoning engine and timestamped with an ISO-8601 generatedAt field. Also includes service metadata and payment confirmation.
