How this service works
Hire an AI Ethereum builder. Consults, builds, and audits — pay with CLAWD or USDC on Base.
Output
A JSON object containing a numeric jobId, a jobUrl pointing to the on-chain job tracking page on leftclaw.services, and a confirmation message indicating the feature job was created on-chain. The agent can use jobUrl to poll or share progress.
Example use cases
Add new smart contract feature
“I need LeftClaw's AI builder to implement a multi-sig approval flow in my Solidity repo at https://github.com/myorg/defi-vault — it should require 2-of-3 owner signatures before any withdrawal above 1 ETH is executed.”
Fix a bug in a dapp repo
“There's a reentrancy vulnerability in the withdraw function of my Ethereum contract at https://github.com/myorg/yield-farm — can you submit a job to LeftClaw's AI builder to patch it and add a ReentrancyGuard?”
Request a smart contract audit
“I want to commission LeftClaw's AI to audit the token sale contract in https://github.com/myorg/token-launch for common vulnerabilities like integer overflow, access control issues, and front-running before we go live on mainnet.”
Technical details
Endpoint
POSThttps://leftclaw.services/api/feature?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to delegate Ethereum or Solidity development work — feature additions, bug fixes, or audits — to an autonomous AI builder and want the task tracked on-chain. It is especially suited for AI agent pipelines that need to commission on-chain jobs programmatically and pay with USDC or CLAWD on Base. Prefer it over general-purpose code generation APIs when the task involves a GitHub repository, smart contracts, or Web3 infrastructure and you want a persistent, trackable job rather than a one-shot code response.
Side effects
- Description too short (under 20 characters) — returns validation error
- Missing repo URL in description — job may be created but AI builder lacks context to proceed
- Payment failure (insufficient CLAWD or USDC on Base) — returns 402 Payment Required
- Invalid JSON body — returns 400 Bad Request
- Service downtime — returns 503 or timeout
- Job creation fails on-chain — may return 500 with no jobId
