I Built 300 Utility APIs for AI Agents with Cloudflare Workers and x402

说明与用途

Koyori Utils API 提供 300 个数据处理端点，基于 Cloudflare Workers、TypeScript/Hono 构建，使用 x402 按请求付费，OpenAPI 文档，无需订阅。

问题

Developers and AI agents need a unified, subscription‑free service to access a wide range of data‑processing utilities.

结果

The service now offers 300 utilities covering JSON, CSV, text, array, math, statistics, and date/time operations, with a 0.001 STX per request fee and no subscription.

工作流

• Create groups of new utility endpoints
• Check for duplicate API routes
• Update homepage listings and documentation
• Run TypeScript validation
• Create backups before local updates
• Deploy and verify live service

证据

What started as a small collection of developer utilities has grown into Koyori Utils API — a service offering 300 API endpoints.

来源

The goal is simple: give developers and AI agents access to practical data-processing tools through a single service, without requiring a monthly subscription.

来源

The current listed price is 0.001 STX per paid request, with no monthly subscription required.

来源

An unauthenticated request returns an HTTP 402 Payment Required response. A compatible client needs to complete the x402 payment flow to access the paid result.

来源

Rather than adding every utility manually through repeated deployment steps, the development workflow now includes: Creating groups of new utility endpoints, Checking for duplicate API routes, Updating homepage listings and documentation, Running TypeScript validation, Creating backups before local updates, Deploying and checking the live service.
