## 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 the-undesirables-oracle-card-verdict-endpoint-7e2b5d10
```

Example prompt: Pull a full verdict on Charizard Base Set Unlimited — product ID 107 — including live comps, the 30-day price forecast with confidence bands, and whether PSA economy grading would be profitable.

## When to prefer this

Use this endpoint when you need a single, authoritative, all-in-one decision package for a specific trading card — covering live market comps, calibrated price forecasting, and grading ROI in one paid call. Prefer this over calling individual forecast, comps, or grade-ROI endpoints separately when you need a coherent, internally consistent verdict and want to minimize latency and cost from multiple round-trips. Best suited for buy/sell/hold decision workflows and grading submission decisions.

## Known failure modes

- Card not found by name or product_id — returns 404 or empty comps
- Ambiguous card name with no product_id provided — may resolve to wrong card
- PSA/TCGPlayer data temporarily unavailable — partial response or degraded forecast
- Invalid service_tier value — defaults to economy or returns validation error
- Insufficient sales history for reliable forecast — wider confidence bands or no forecast returned

## How this service works

The Decision Endpoint: one paid call composing everything a collector or agent needs to act on a card — live comps (raw + observed PSA/BGS/CGC graded asks), the conformal-calibrated 30-day forecast (median, 5th–95th bands, honest VaR, Safe-Hold and Momentum grades), and a grade-ROI answer, plus a deterministic MARKET STANCE grade. Composed from the same internals the individual endpoints serve, so it can never disagree with them. Not financial advice — a calibrated market read.

## Output

A composed JSON response containing: live comparable sales (raw and graded asks from PSA/BGS/CGC), a conformal-calibrated 30-day price forecast (median with 5th–95th percentile bands, honest VaR), Safe-Hold and Momentum grades, a grade-ROI answer indicating whether grading is financially justified, and a deterministic MARKET STANCE grade summarizing the overall market position.
