# Ardaro Context Compression Analyzer

> Ardaro Context Compression Analyzer is a paid API for AI agents from agents.getardaro.com, paid per call via x402, $0.05/call, status unknown (last checked 2026-09-14).

Analyzes and compresses agent prompt/context payloads by reducing redundant whitespace and line breaks while preserving semantic content, flagging cases requiring human review.

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 ardaro-context-compression-analyzer-661a84a9 -d '<json body>'
```

Example prompt: Can you analyze and compress this agent context to remove redundant line breaks — here's the prompt: 'system: You are a helpful assistant.\n\n\n\nuser: What is the capital of France?' — and tell me if it's safe to use automatically or needs human review?

## When to prefer this

Choose this endpoint when you need a lightweight, rule-based whitespace and line-break compression pass on LLM prompts or agent context payloads, especially when you want a safety signal (human review flag) before applying changes. It is not a lossy semantic summarizer — prefer it when you want to reduce token count purely by eliminating redundant formatting without removing any words or role headers. Best suited for pipelines where cost per token matters and you want an auditable transformation log with a result identity hash for traceability.

## Known failure modes

- Input payload missing or malformed — returns error without compression result
- Prompt contains ambiguous role headers that cannot be safely transformed — flagged as REVIEW_CANDIDATE with human_review_required=true
- No compressible whitespace found — returns original payload with compression_ratio of 0 or null
- Payment not confirmed (x402 protocol failure) — request rejected before processing
- Semantic preservation cannot be verified — semantic_preservation_verified returns false, human review flagged

## How this service works

Evidence-bounded visibility into publicly discoverable x402 agent services.

## Output

Returns a JSON object containing the compressed prompt payload, transformation description (e.g. which line-break rules were applied), compression ratio, original vs candidate character counts, characters removed, tokens saved (if measurable), tokenizer used, a status field (e.g. REVIEW_CANDIDATE), flags for whether human review is required and whether semantic preservation and latency/cost savings have been verified, plus a unique result identity hash and service/contract metadata.
