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.
Example use cases
Pre-purchase card investment decision
“I'm thinking about buying a first-edition Blastoise — TCGplayer product ID 14252. Can you give me the full market verdict: live graded comps, the 30-day forecast with risk bands, and whether it's a buy or hold right now?”
Grading ROI check before submission
“I've got a raw Charizard VMAX — product ID 224517 — and I'm considering PSA economy grading. Pull the full verdict so I can see the grade-ROI answer and MARKET STANCE before I decide.”
Portfolio card sell timing decision
“I own a PSA 10 Pikachu Illustrator — card name 'Pikachu Illustrator' — and I want to know if now is the right time to sell. Give me the full oracle verdict with momentum grade, VaR, and 30-day forecast bands.”
Technical details
Endpoint
GEThttps://oracle.the-undesirables.com/api/v1/verdictWhen to prefer
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.
Side effects
- 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
