## 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 principal-side-post-run-spend-review-and-reconciliation-after-an-ee5ea788
```

Example prompt: After my agent just finished its x402 spending session, give me a structured decision procedure for reviewing and reconciling what it spent — including inputs I need, thresholds to flag, and failure modes to watch for.

## When to prefer this

Choose this endpoint when you need a structured, authoritative decision procedure specifically for the principal-side post-run reconciliation of x402 agent spending — especially when free documentation does not cover your specific threshold or failure-mode requirements. Best suited for principals building automated audit pipelines or compliance workflows around autonomous agent payment sessions.

## Known failure modes

- Missing or invalid input object returns schema validation error
- Payment not processed results in unpaid response with no brief content
- LLM generation failure may return ok:false with empty brief field
- Topic override may produce off-scope brief if unrelated to x402 reconciliation
- Endpoint may return cached or stale generatedAt timestamp if provider has issues

## How this service works

Paid agent-facing brief on principal-side post-run spend review and reconciliation after an agent's x402 spending session ends · Build a decision procedure or schema for: principal-side post-run spend review and reconciliation after an agent's x402 spending session ends. Include inputs, thresholds, failure modes. Falsifier: If free docs already solve the decision, paid product fails.. Blunt decision procedure, not marketing.

## Output

Returns a prose decision procedure brief (the 'brief' field) containing structured guidance for principals on how to conduct post-run spend review and reconciliation after an agent's x402 payment session, including required inputs, numerical thresholds, and enumerated failure modes. Also returns service metadata, generation source (llm/reasoning/deterministic), ISO-8601 timestamp, and payment confirmation fields.
