Haima
Agentic finance engine for the Agent OS — x402 machine-to-machine payments, on-chain settlement, per-task revenue billing, and wallet management. Integrates with Arcan (agent runtime), Autonomic (economic homeostasis), and Lago (event-sourced persistence) to give agents real financial agency. Use when: (1) adding payment capabilities to an agent or agent-controlled API, (2) implementing x402 protocol support for HTTP-native machine payments, (3) wiring per-task billing so agents can charge for completed work, (4) managing agent wallets (secp256k1 keypair, encrypted storage), (5) configuring payment policies (auto-approve, spend caps, rate limits), (6) integrating Coinbase CDP or self-hosted facilitators for on-chain settlement, (7) bridging on-chain USDC with Autonomic's micro-credit state. Triggers on 'agent payments', 'x402', 'machine payments', 'agentic finance', 'haima', 'payment port', 'wallet management', 'per-task billing', 'USDC payments', 'agent revenue', '402 payment required'.

From the source SKILL.md
Haima (αἷμα, Greek for "blood") is the circulatory system of the Agent OS — it distributes economic resources throughout the organism. Agents can pay for external resources, charge for completed tasks, and maintain sovereign wallets, all through standard HTTP via the x402 protocol.
What this skill does
Haima is a community-contributed Claude Code skill in the security-misc sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/haima/ and loads when your prompt matches the skill's trigger.

When should I use the Haima skill?
Use Haima when your Claude Code task falls under the Security category — specifically in the security misc area. Claude Code auto-discovers installed skills and invokes the right one based on the task description, so you can also ask Claude directly (e.g. "use Haima" or describe the task and let Claude pick). Browse related skills at
/category/security/.
What is a Claude Code skill and how does the Haima skill fit in?
A Claude Code skill is a
SKILL.md file that lives under
~/.claude/skills/<name>/ and tells the Claude Code CLI agent how to perform a specific task (instructions, prompts, allowed tools). Skills are auto-discovered at session start. Haima is one of 67,000+ skills indexed in the open ClaudSkills catalog, classified under the Security category. Learn more at
