How this service works
Trust, discovery, and fiat settlement layer for AI agent commerce. Dual-protocol: accepts both x402 and MPP payments in USDC on Base. EUR/GBP/USD fiat settlement via SEPA Instant.
Output
Returns a numeric quality score (e.g. 7.5 out of 10), an array of issues each containing line number, message, severity (e.g. warning/error), and a suggestion, plus a plain-English summary of the overall code quality.
Example use cases
Automated code review for pull requests
“Before I merge this pull request, can you review the new code changes and give me a quality score? Flag any issues with line numbers and severity levels, and suggest improvements where you see problems. Here's what was added: `function calculateDiscount(price, percent) { const discount = price * percent; return price - discount; }`”
Detect bugs and code smells
“I'm worried there might be some bugs or code smells in this module. Can you analyze it for me, give it a quality score, and walk me through any issues you find with line numbers and severity? Here's the code: `function getUserData(id) { var user = database.query(id); if (user) { return user; } }`”
Check code quality before deployment
“Help me make sure this code is production-ready. Can you review it for quality issues, give me a numeric score, and tell me what needs fixing with line-by-line feedback and suggestions? Here's the function I want to deploy: `async function fetchAndProcess(url) { let response = fetch(url); let data = response.json(); return data.map(x => x.value); }`”
Technical details
Endpoint
POSThttps://x402.asterpay.io/v1/ai/code-reviewWhen to prefer
Choose this endpoint when you need a per-call, pay-as-you-go code review with line-level granularity and a numeric quality score, especially within an AI agent workflow that handles x402 micropayments in USDC on Base. Prefer it over static linting tools when you want a blended quality score with natural-language suggestions per issue.
Side effects
- Empty or missing code body returns a 400 validation error
- Extremely large code submissions may time out or be rejected
- Malformed request body returns a parsing error
- Payment not attached or insufficient USDC balance returns a 402 Payment Required
- Unsupported language or binary content may produce low-confidence results
