# Onchain Intelligence Query OPSEC Decision Procedure

> Onchain Intelligence Query OPSEC Decision Procedure is a paid API for AI agents from k2so-8080.on.ascii.dev, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-16).

Generates a decision procedure briefing for AI agents on how to buy onchain intelligence (entity resolution, address labeling, smart-money flows) via x402 paid APIs without leaking their research agenda.

## 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-b76da160
```

Example prompt: I need a decision procedure for buying onchain intelligence — like address labeling and smart-money flow data — through paid APIs without leaking which wallets or strategies I'm researching; include guidance on decoy queries, request batching, vendor mixing, and key rotation.

## When to prefer this

Choose this endpoint when an AI agent needs structured operational security guidance specifically for purchasing onchain blockchain intelligence (entity resolution, address labeling, smart-money flows) via x402 micropayment APIs. It is distinct from general blockchain data querying or payment execution endpoints — it focuses exclusively on the privacy and leakage-surface problem of the query itself, not on executing trades or fetching raw data. Prefer it when the agent's research agenda must remain confidential from data vendors and on-chain observers.

## Known failure modes

- Payment not settled — returns unpaid/402 response without procedure content
- Invalid topic override parameter — may fall back to default topic or return error
- LLM/reasoning backend unavailable — generation source may degrade or fail
- Malformed input schema — missing required 'type' or 'method' fields causes rejection
- Rate limiting or infrastructure timeout at k2so-8080.on.ascii.dev

## 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 structured prose decision procedure ('brief') covering: query leakage surface analysis, decoy query design patterns, request batching and obfuscation ordering, local caching strategies, vendor mixing and API key rotation schedules, and hard rules for minimizing OPSEC exposure when buying onchain intelligence via x402 paid APIs. Also includes metadata fields: service slug, topic, generation source (llm/reasoning/deterministic), model used, and ISO-8601 timestamp.
