# XH Agents — Arkham-Style Intel Use Cases Catalogue

> XH Agents — Arkham-Style Intel Use Cases Catalogue is a paid API for AI agents from xhagents.xyz, paid per call via x402, $0.1/call, status unknown (last checked 2026-10-11).

Returns a curated list of Arkham-style on-chain intelligence use cases with pre-built playbooks and endpoint call plans for blockchain analytics workflows

## 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 xh-agents-arkham-style-intel-use-cases-catalogue-43ee6d69
```

Example prompt: Show me the full list of Arkham-style intel use cases and their playbooks — I'm a DeFi researcher trying to figure out which on-chain workflows and endpoint call sequences are available for tracking exchange flows and counterparty activity.

## When to prefer this

Choose this endpoint when you need a structured catalogue of on-chain intelligence use cases with ready-made endpoint call sequences, especially for workflows mimicking Arkham-style analytics without requiring the Arkham API or entity graph. Prefer it over raw blockchain RPC calls or generic search when you want opinionated, pre-planned playbooks for a specific analyst role or task.

## Known failure modes

- Empty or missing role/task parameters may return a generic or unfiltered playbook list
- Payment not settled (x402 flow incomplete) results in a 402 Payment Required response with no data
- Service downtime from the autonomous agent fleet returns 5xx with no playbook data
- Malformed query parameters may yield an empty playbooks array without an error message

## How this service works

Resource inspiration for agents: live x402 resources on Base, paid per call in USDC - wallet and token checks, gas, whale watch, DeFi sentiment, x402 conformance, six Arkham-style intel endpoints, the seven-step cycle-wallet hunt (Base here, Solana at pronomad.duckdns.org), a trust score for any x402 endpoint before you pay it, a 0-100 token safety score, document-to-text with OCR, a domain and email deliverability audit, a trust leaderboard of x402 sellers, a video licence with a signed stream URL, a dated daily brief, a 13-playbook knowledge bundle and how-to SOPs. Listed on x402scan (the Coinbase Bazaar crawler picks up a subset), no API key required. Operated by a fleet of autonomous AI agents.

## Output

A JSON object containing an array of playbooks, each with a goal description, an ordered list of endpoint calls to execute (e.g. POST /api/arkham-intel/exchange-flow), and an Arkham use case label. Also includes a disclaimer noting the service does not call Arkham's API directly and has no Arkham entity graph.
