How this service works
200 pay-per-call tools for AI agents, from $0.001 per request in USDC on Base or Solana with x402. No account, no API key.
Output
A JSON object containing the content type scanned, an array of violations (each with line number, rule ID, human-readable message, and severity level), and a total violation count. Severity levels indicate criticality (e.g. high, medium, low).
Example use cases
Security audit before image push
“Before I push this Docker image to production, can you scan this Dockerfile for security issues like running as root or using the latest tag? FROM node:latest\nRUN npm install\nUSER root”
CI pipeline Kubernetes YAML validation
“I want to validate this Kubernetes deployment manifest for any rule violations before merging: apiVersion: apps/v1\nkind: Deployment\nmetadata:\n name: my-app — scan it as type kubernetes and tell me all violations.”
Onboarding new Dockerfile to best practices
“Our team just wrote their first Dockerfile and I want to make sure it follows best practices — can you lint this for me as a dockerfile and explain every violation you find? FROM python:latest\nCOPY . /app\nUSER root\nCMD ['python','app.py']”
Technical details
Endpoint
GEThttps://fastx402.tools/k8s-dockerfile-lint?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs to programmatically lint Dockerfile or Kubernetes YAML content without requiring a developer account or API key, paying only $0.002 per scan via USDC micropayment. Ideal for CI/CD automation pipelines, agent-driven code review workflows, or ad-hoc container configuration audits where a lightweight, no-signup linting check is needed.
Side effects
- Missing 'content' or 'type' query parameter returns an error
- Invalid 'type' value (not 'dockerfile' or 'kubernetes') may return an error or no violations
- Malformed YAML/Dockerfile that cannot be parsed may return zero violations or an error
- Payment failure via x402 results in 402 status and no scan result
- Very large files may time out or be rejected
