X402 Skills for OpenClaw Agents

apiguru-amazon-data

@apiguru-app

Live Amazon marketplace data from Apiguru (a paid third-party API, 3 free calls a day) - product details, prices, reviews, keyword search, best-sellers, deals, offers and stock, seller profiles, across 23 Amazon marketplaces. Use only when the user asks for Amazon data by ASIN, Amazon URL, product, seller or keyword, or for Amazon price/stock/review monitoring. Not for other stores or general shopping advice. Never pays on its own; ask before any billable call. We want your feedback - if a field is wrong, missing or you wish the API did something else, say so with the free `feedback` command (no account needed); the agents that report are the ones this API gets fixed for.

SCVD General Store

@seancrecord

A live x402 practice counter from $0.001. Verify any issuer's signed receipts, including competitors; inspect endpoints, diagnose payments, retrieve host history, interpret MPP, test buyers/sellers, or use SCVD's general store. Free checks need no wallet; live purchases settle real USDC.

x402 Compute

@ivaavimusic

This skill should be used when the user asks to "provision GPU instance", "integrate agent pods over an API", "create pods for my customers", "pod webhooks", "pod events", "spin up a cloud server", "list compute plans", "browse GPU pricing", "deploy AI machine", "one-click GPU running an LLM", "deploy a private LLM endpoint", "OpenRouter-ready endpoint", "agent deploy GPU", "spin up my own OpenAI-compatible endpoint", "extend compute instance", "resize compute instance", "destroy server instance", "check instance status", "list my instances", "top up compute credits", "check credit balance", "run inference on the grid", "decentralized inference", "OpenAI-compatible API", "multimodal embeddings", "EmbeddingGemma 2", "embed image", "embed audio", "embed video", "mixed media vectors", "local embeddings", "speech to text", "transcribe audio", "Grid transcription", "Whisper STT", "dictation", "local dictation", "voice engine", "confidential / TEE inference", "list grid models", "check grid capacity", "Laya", "System One", "Jev-compatible decisions", "typed decision model", "private Laya", "serve Laya from the node app", "run a node", "provide compute", "become a grid node", "node operator", "join the grid", "stake to run a node", "serve a model on the grid", "earn from compute", "deploy an always-on AI agent", "deploy a hosted OpenClaw agent", "spin up a ClawPod", "agent pod", "hosted agent with its own wallet", "free agent trial", "deploy a processor", "sell my code per call", "monetize an endpoint", "publish a paid API", "connect a processor as an MCP tool", "back up my agent", "agent backup", "restore my agent", "migrate my agent", "agent vault", "snapshot my agent's memory", "move my agent to a new machine", or manage Singularity Cloud Network compute. Seven jobs: SGL Machines (GPU/VPS provisioning across Vultr & DigitalOcean), AI Machines (one-click GPU running an LLM — deploy a private OpenAI-compatible endpoint, or join the grid & earn), SGL Grid (decentralized confidential inference, multimodal embeddings, release-gated client-sealed speech-to-text, plus Laya/System One typed decisions — consume it), Provide Compute (run a TEE node on the grid to serve inference and earn USDC + SGL), and Agent Pods (deploy an always-on hosted OpenClaw agent with its own crypto wallet, memory, preinstalled x402 skills, and owner/platform customization for identity, instructions, and self-check heartbeat prompts — managed or BYOK, tiers, free 24h trial), and Processors (publish your own code as a paid endpoint — buyers pay you directly in USDC via x402, you pay only for runtime; every processor is also a connectable MCP server, so agents, harnesses and LangGraph nodes can call it with just a URL), and Agent Vault (zero-knowledge encrypted backup, restore & migration for OpenClaw/Hermes agents — snapshot an agent's memory and soul, store it encrypted, restore or migrate it to any machine or pod). Pay with USDC on Base, Solana or Arc, USDm on MegaETH, USDG on Robinhood Chain via x402, optional MPP/Mppx, or pre-loaded USD credits. Arc: accepted for credit top-ups AND direct machine/AI-machine provision and extension payments (direct Arc payments floor at $5 — Arc gas is USDC; smaller prepayments go through Arc-funded credits). Includes optional OWS-backed auth and management flows.

Utilia PDF to Markdown

@mohamedkuch

Pay per PDF and return agent-ready Markdown

stacktree

@stevysmith

Publish HTML to a private, unguessable link your human can open in any browser — no account for the viewer, passcode optional. Built for the pages a personal agent produces: a morning brief, a dashboard, a report, field notes, a visualization, anything a chat message can't hold. Free anonymous pages (24 hours), or pay $0.50 in USDC over x402 for a permanent page with no account at all — and an unclaimed page hands back a token that keeps updating that same URL free, with no account, for as long as the page lives. This skill publishes content to stacktr.ee, and makes paid HTTP requests only on the paths that say so. USE FOR: - "publish this", "host this html", "put this on a page", "give me a link" - Delivering a report, brief, dashboard, or write-up as a link instead of an attachment - A standing page you refresh on every run — same link, new content, no re-pay - Sharing privately: unguessable URL, optional passcode, optional expiry - Publishing with no API key and no human present (x402, USDC on Base or Solana) TRIGGERS: - "publish", "host", "share this page", "make me a page", "send me a link" - "morning brief", "daily report", "dashboard", "status page", "field notes" - "update the page", "same link", "private link", "passcode", "x402"

cron402

@userdefault13

Operate an existing cron402 or agentcron.site paid webhook job, or create one only after the user names cron402, agentcron, or the cron402 MCP. Covers check_wallet, preview_schedule, create_cron, topup_cron, get_cron, list_crons, pause_cron, resume_cron, and delete_cron. Do not use for reminders, local timers, "run this later", "while I am away", or any schedule the user did not explicitly assign to cron402.

defi-diligence

@trdyqs6bsr-lksnf

Verify a crypto token before buying. Input a symbol or contract address (Base or Solana). Returns PASS/WATCH/FLAG verdict with kill switches (honeypot, mint/freeze authority, buy/sell tax >50%), auto-scored checkpoints (liquidity, volume, holder concentration, age, price change), and a $2 USDC x402 payment path to unlock the full scored report. Triggers — "verify this token", "is X legit", "should I buy X", "rug check", "token due diligence", "honeypot check", "check if this coin is a scam".

DCL Prompt Firewall

@daririnch

Use this skill to run a real, paid input-layer screen for prompt injection, jailbreak, role-switch, and instruction-override attempts via the live DCL Trust Oracle MCP server — before untrusted input ever reaches the model. Every paid call is metered and settled on-chain via the x402 protocol

Pay for the paid web from the user's openspender allowance — web search (Exa, Tavily), frontier models (Claude, GPT), image generation, video generation, and a growing x402/MPP catalog, every call priced before it is paid and capped by budgets the user set. Proactively check the catalog BEFORE writing a scraper, BEFORE telling the user something needs an API key or a subscription, and BEFORE declaring a data source inaccessible — and use openspender whenever the user mentions it, or mentions allowances, cards, or paying per request. Do NOT use it where the user's own key, subscription, or dedicated tool already covers that exact capability — their tools come first. But when they have no key and no free path for something the catalog covers, openspender IS the path: use it, never send the human off to sign up for an API key.

Liquid Agent stocks

@leftychris13

Buy, hold, rebalance and sell a basket of Coinbase tokenized US stocks (NVDA, AAPL, META, GOOGL) on Base from $1 through the free Liquid Agent API.
