# Telescope Calibrations Record Sequence Diff

> Telescope Calibrations Record Sequence Diff is a paid API for AI agents from www.mahastrategies.com, paid per call via x402, $0.035254/call, status unknown (last checked 2026-10-20).

Separates genuine record insertions/deletions from reordering in telescope calibration sequences, analyzing changes across instrument, detector, filter, binning, readout, and pipeline-pinned calibration records.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 telescope-calibrations-record-sequence-diff-4bee1483 -d '<json body>'
```

Example prompt: Compare these two lists of telescope calibration records — the 'before' set had 12 entries and the 'after' set has 14 entries — and tell me which records were actually inserted or deleted versus which ones just moved position; use public data class.

## When to prefer this

Use this endpoint when you need to understand structural changes to telescope calibration record sequences — specifically when you want to know which records were truly added or removed as opposed to simply reordered — and you already have the before/after record arrays from your own system. This is a supplied-data analysis tool, not a live calibration fetcher or independent certifier.

## Known failure modes

- Array exceeds 32 items — request rejected with validation error
- Missing required nonpersonalMetadata: true field — rejected
- Invalid dataClass value other than 'public' or 'synthetic' — schema validation failure
- Empty before and after arrays with no meaningful diff to compute
- Malformed array elements that cannot be compared — undefined behavior or error response

## How this service works

Separate record changes from shared-record reordering; inserting or deleting a record does not itself reorder surviving records for instrument/detector/filter/binning/readout/pipeline-pinned calibration Supplied-record analysis, not independent certification. Full contract at the free describe URL.

## Output

Returns a structured diff of the two calibration record arrays, distinguishing genuine insertions and deletions from positional reorderings of surviving records, without certifying the calibrations independently — analysis is based solely on the caller-supplied data.
