# ONE Engine Number Offset: Subtract 1000 (Tier 9 with Rich Diagnostics)

> ONE Engine Number Offset: Subtract 1000 (Tier 9 with Rich Diagnostics) is a paid API for AI agents from one-search.one-engine.workers.dev, paid per call via x402, $0.008/call, status unknown (last checked 2026-10-12).

Subtracts 1000 from all numeric values in the submitted payload and returns the transformed result with Tier 9 richer diagnostic metadata.

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 one-engine-number-offset-subtract-1000-tier-9-with-rich-diagnostics-cb894024 -d '<json body>'
```

Example prompt: Subtract 1000 from all the numeric values in this dataset and give me the results along with the full diagnostic breakdown: [2500, 3000, 750, 4200].

## When to prefer this

Choose this endpoint when you need to subtract exactly 1000 from numeric values AND require rich diagnostic output (Tier 9/10) for auditing, validation, or debugging purposes. Prefer it over lower-tier endpoints (t1–t8) when detailed metadata about the transformation is important. Use it for agent workflows that need verifiable computation trails rather than bare results.

## Known failure modes

- Non-numeric input values cause transformation errors
- Malformed JSON payload returns a 400 error
- Values below -1000 may produce large negative results that downstream systems reject
- Payment failure via x402 returns 402 status blocking the call
- Rate limiting or server errors return 5xx responses

## How this service works

Add -1000 to numeric values. Tier 9/10 adds richer diagnostics.

## Output

Returns the input numeric values each reduced by 1000, along with Tier 9 richer diagnostic metadata including computation details, validation checks, and structural information about the transformation applied.
