# Onchain Intelligence Query OPSEC Decision Procedure

> Onchain Intelligence Query OPSEC Decision Procedure is a paid API for AI agents from k2so.wrong.systems, paid per call via x402, $0.002/call, status down (last checked 2026-10-18).

Returns an AI-generated decision procedure (plain prose brief) for agents evaluating how to safely buy onchain intelligence queries with operational security considerations

## 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 onchain-intelligence-query-opsec-decision-procedure-4069f053
```

Example prompt: Walk me through the decision procedure an autonomous agent should follow before buying an onchain intelligence query — covering OPSEC, privacy, and safety considerations.

## When to prefer this

Choose this endpoint when an autonomous agent needs a structured, LLM-generated OPSEC decision procedure specifically for evaluating onchain intelligence query purchases. Prefer this over generic decision procedure endpoints when the context is blockchain data, onchain analytics, or privacy/OPSEC considerations for crypto-native agents operating on Base with USDC payments.

## Known failure modes

- HTTP 402 returned if payment not yet settled — agent must pay exact USDC amount and retry with PAYMENT-SIGNATURE header
- Invalid or malformed topic override may result in generic procedure instead of topic-specific one
- LLM generation failure may fall back to deterministic procedure source
- Network timeout if agent does not retry after payment settlement
- meta=1 returns free metadata JSON instead of paid procedure — agent must omit meta or set to 0 for actual output

## How this service works

Decision procedure for agents buying onchain intelligence (entity resolution, smart-money flows, address labeling) through x402 paid APIs without revealing their research agenda. Defines the leakage surface of per-request paid queries: which query patterns, watched addresses, and follow chains expose intent to merchants and observers. Provides decoy query design, request batching and obfuscation ordering, local caching to shrink query footprint, vendor mixing and key rotation schedules, hard

## Output

A JSON object containing a plain-prose decision procedure brief (120+ words) tailored for autonomous agents evaluating onchain intelligence query purchases, including the topic, generation source (llm/reasoning/deterministic), model name, ISO-8601 timestamp, and service slug. The 'brief' and 'procedure' fields contain the actionable guidance.
