Agent Shopping Protocol v0.1
The wallet for AI agents
Fund one SkillBoss wallet and let your agent spend against 354+ tools: 100+ LLMs (Claude, GPT, Gemini, DeepSeek, Grok), web scraping, search, image/video/audio generation, email, and more. Every call is signed, audited, and budget-capped. Free $0.50 trial — no signup.
What you get
One API key for everything
Stop managing 10+ vendor accounts. Fund one SkillBoss wallet, spend against 100+ LLMs, web scraping, search, image/video/audio generation, email, and 354+ more.
Signed JWT receipts
Every /v1/run response returns a tamper-proof signed receipt. CFO, compliance, or any third party can verify spend offline via /api/receipts/verify.
Sub-wallet delegation
Mint scoped sub-wallets via /api/wallet/sub-wallets and hand one per agent in a swarm. A runaway worker can only drain its own slice, never the parent account.
Server-side spending rules
Set per-skill / per-day / per-call caps via /api/wallet/rules. Enforced server-side on every call — no agent can override them.
Agent Shopping Protocol v0.1
SkillBoss is the reference implementation of ASP v0.1, an open MIT-licensed spec. Not lock-in — anyone can run a compatible shop.
x402 + MPP + wallet rails
Three payment protocols supported. Deterministic pricing routes to x402 by default, usage-based to MPP, everything else to the wallet.

What is an "agent wallet"?
A prefunded SkillBoss balance that an AI agent can spend against any of 354+ tools. Instead of your agent needing a credit card and a separate account per vendor, it uses one API key and one wallet. Every call is logged and signed.
How is this different from an OpenRouter-style LLM gateway?
Two differences. First, SkillBoss has 354+ tools, not just LLMs — web scraping, search, image/video generation, email, SMS, databases, hosting. Second, SkillBoss implements Agent Shopping Protocol v0.1, which adds signed receipts, spending rules, sub-wallet delegation, and an open discovery protocol (/api/catalog, /api/agent/bootstrap).
Can I try it without signing up?
Yes. POST https://www.skillboss.co/api/try/anonymous-wallet and you get a real $0.50 SkillBoss API key instantly. No email, no credit card, rate limited to 1 per IP per day. Leftover balance can be claimed into a real account later.
How do I stop an agent from draining the wallet?
Three layers. (1) Per-call hard cap via the X-Max-Cost-Usd header. (2) Per-skill / per-day budgets stored server-side via /api/wallet/rules. (3) Per-agent budget caps via /api/wallet/sub-wallets — hand each agent its own scoped sub-wallet.
What does the signed receipt look like?
Every /v1/run response includes a `receipt` field — a JWT signed with HS256 carrying skill, cost_usd, wallet_balance_after_usd, timestamp, and user_id. POST the raw string to /api/receipts/verify and get {valid, claims, error}.
