## 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 coil-point-in-time-scores-51b53691
```

Example prompt: Pull the Coil point-in-time scores as they were published on January 10, 2025 — I need the opportunity percentile, entry quality, and hold strength for every name in the archive so I can backtest without lookahead bias.

## When to prefer this

Choose this endpoint when you need historically accurate, as-published Coil scores for a specific past date — particularly for backtesting or strategy validation where lookahead bias must be eliminated. Use it over the live scanner or single-name endpoints when the research question is about what was knowable at a past point in time, not what is actionable today. Prefer it when you need the full cross-section of names (not just one stock) at a historical snapshot.

## Known failure modes

- Requested date has no archive entry — returns empty result or 404 if that date was not a publish day
- Invalid date format (not YYYY-MM-DD) causes a bad request error
- Date in the future returns no data since scores are only appended on publish days
- Network or payment failure (x402) results in 402 Payment Required if USDC payment is not included

## How this service works

Point-in-time score history — what did Coil actually publish on a given date? Returns the as-published per-name scores (opportunity percentile, entry quality, hold strength) for every S&P 500 / Nasdaq-100 / macro name on any archived date (?date=YYYY-MM-DD; omit for the list of archived dates). Lookahead-bias-clean by construction: served verbatim from the append-only publish log, never recomputed. Immutable: one new date per session, never revised. Research, not advice.

## Output

Returns a collection of as-published scores for every covered name (S&P 500, Nasdaq-100, macro) on the requested date, including opportunity percentile, entry quality, and hold strength — served verbatim from Coil's append-only publish log. If no date is specified, returns the list of all available archived dates.
