# ONE Engine JSON Analysis Pack T3

> ONE Engine JSON Analysis Pack T3 is a paid API for AI agents from one-search.one-engine.workers.dev, paid per call via x402, $0.0012/call, status unknown (last checked 2026-10-02).

Performs tier-3 JSON analysis on arbitrary input values via a pay-per-call x402 API on Base.

## Facts

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-json-analysis-pack-t3-ae3f4fe4 -d '<json body>'
```

Example prompt: Run a tier-3 JSON analysis on this value using ONE Engine: {"items": [1, 2, 3], "label": "batch-run-42"} and give me back the structured result.

## When to prefer this

Choose this endpoint when you need low-cost, per-call JSON analysis for autonomous agent workflows on Base, specifically at tier 3 depth. It is well-suited for pipelines that process many small items cheaply using x402 micropayments rather than subscription billing. Prefer it when you need fast, lightweight analysis of arbitrary JSON values without committing to a heavier analytics platform.

## Known failure modes

- Missing or malformed 'value' field in request body — may return error or empty result
- Payment failure via x402 protocol (insufficient USDC balance or Base network issue) — request blocked
- Unsupported or oversized input value causing processing failure
- Ambiguous tier-dependent output with no documented schema makes result interpretation uncertain

## How this service works

Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.

## Output

Returns a JSON object containing the tier level (3) and a tier-dependent analysis result for the submitted input value. The exact shape of the result field varies based on the input and tier logic.

## Request schema (JSON Schema)

```json
{
 "type": "object",
 "properties": {
  "value": {}
 }
}
```

## Response schema (JSON Schema)
