# Oblique Markets Reprice Regret

> Oblique Markets Reprice Regret is a paid API for AI agents from api.oblique.markets, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-14).

Returns a seller-side repricing analysis for an x402 Bazaar listing, showing price change events, USDC revenue counterfactuals, peer medians, and a plain-English verdict over a 7–90 day window.

## 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 oblique-markets-reprice-regret-616470ef -d '<json body>'
```

Example prompt: Can you pull a 30-day reprice regret report for my x402 Bazaar listing at https://x402.shizu.me/crypto and tell me whether my price changes cost me or earned me more USDC compared to what I would have made at the old price?

## When to prefer this

Use this endpoint when a seller wants to retrospectively evaluate the financial wisdom of their x402 Bazaar price changes — specifically to get a USDC revenue counterfactual (what they would have earned at the old price) rather than just raw analytics. Prefer it over generic price-stats endpoints when you need per-event verdicts, peer comparisons, and an auditable evidence hash tied to daily snapshot history.

## Known failure modes

- No repricing events found returns status: no_repricing_observed with price history but empty repricing_events array
- Invalid or unknown resource_url returns an error or empty result
- seller_payto with no Bazaar listings returns empty paginated result
- window_days outside 7–90 day range may return a validation error
- Cursor-based pagination exhaustion returns empty page with no next cursor
- Network parameter mismatch (e.g. wrong chain ID) may yield no snapshot data

## How this service works

Use when an agent needs reprice regret. Returns Seller-side repricing report from daily x402 Bazaar snapshot history for one listing (resource_url) or every listing paid to one address (seller_payto, 25 per page) over a 7–90 day window: price change points, each repricing event with 30d calls and payers before and after, a per-event USDC revenue counterfactual on observed volume (regret_usdc), a one-line verdict, peer medians, an evidence hash; one observed price returns no_repricing_observed. $

## Output

A JSON object containing: listing status, repricing events (each with before/after call volume and payer counts, price ratio, a USDC revenue counterfactual labeled regret_usdc, and a one-line verdict), full price history snapshots, peer median price and payer stats, network, snapshot window, an evidence hash for auditability, and a top-level status field (repricing_observed or no_repricing_observed).
