Vibecode SharpAPI
track this build5 steps, step by step0%Any single endpoint here, summarize a text, categorize a product, parse a resume, is one LLM call with a decent prompt and a JSON schema, so the piece you actually need is often an evening of work. What you will not rebuild in a weekend is the catalog: 30+ endpoints with tuned prompts, response contracts that survive model upgrades, an async job queue with polling, and maintained SDKs. Rebuild the two or three endpoints you use, pay when you need the shelf.
You are building a lean indie version of SharpAPI. Create the following project files first, then implement the application by following them. Keep the files updated as decisions change. Do not collapse this into a single README or prompt. ===== README.md ===== # SharpAPI indie build ## Goal Build the smallest trustworthy replacement for the core SharpAPI workflow for one developer or a tiny team. ## Scope Wrap OpenAI or Anthropic structured outputs in a small local API: one prompt file and one JSON schema per task, a SQLite job table for async processing, and a worker that retries failures. ## Quick start 1. Install the documented dependencies. 2. Copy `.env.example` to `.env`. 3. Run the development command chosen during implementation. 4. Complete the acceptance checks in `BUILD_PLAN.md`. ## Honest limits This build deliberately does not replace: - tuned prompts per use case, tested against messy real-world inputs - response contracts that stay stable when the underlying models change - the managed async queue with polling, throttling, and rate limits - ready SDKs for PHP/Laravel, Node, and Python - 80+ language coverage tested per endpoint If those capabilities are essential, use OpenAI Node SDK instead of pretending the gap is solved. ===== AGENTS.md ===== # Agent instructions - Optimize for a working, understandable weekend build. - Prefer the fewest moving parts that satisfy the brief. - Do not invent cryptography, security guarantees, APIs, or compliance claims. - Keep secrets out of source control and logs. - Add focused tests for destructive, security-sensitive, and data-loss paths. - Run the project checks before declaring the build complete. - Record any deliberate shortcut in the README under "Tradeoffs". ===== BUILD_PLAN.md ===== # Build plan ## Original build brief Build me a personal AI text-workflow API to replace SharpAPI. Requirements: - Node 22 + Express bound to localhost, better-sqlite3 for storage, no frontend. This is an API my other projects call with curl or fetch. - Three endpoints to start: POST /summarize, POST /categorize against my own category list in categories.json, and POST /parse-resume (PDF or text in, structured JSON out). - Every endpoint calls OpenAI structured outputs with a JSON schema kept in schemas/<task>.json and a prompt kept in prompts/<task>.md, so I can tune prompts without touching code. Adding a task means adding one schema + prompt pair. - Async by default: POST returns a job id, GET /jobs/:id returns status and result. Jobs live in a SQLite table with created/started/finished timestamps. - A worker loop processes jobs with concurrency 2, retries twice on 429 and 5xx with backoff, and stores the error text on the job instead of dropping it. - Parse PDFs with pdf-parse before sending text to the model. - API key from .env. No accounts, no telemetry, binds to localhost only. - Out of scope: billing, rate-limit tiers, packaged SDKs, and the other 27 SharpAPI endpoints. Do not build an admin UI. - README: setup, .env keys, one example curl per endpoint, and a rough per-call cost note. ## Required capabilities - OpenAI or Anthropic API key - a JSON schema per task for structured outputs - a job queue (BullMQ + Redis, or a SQLite job table) - real sample inputs to calibrate each prompt against ## Delivery order 1. Scaffold the smallest runnable application and document its commands. 2. Implement the primary data model and core workflow. 3. Add validation, safe failure states, and persistence. 4. Cover the critical path with automated tests. 5. Exercise a clean install from the README and fix every missing step. ## Done when - A new user can go from clone to first successful workflow using only the README. - The core workflow works without paid infrastructure unless the brief requires it. - Tests cover the highest-risk behavior. - Known limitations are explicit rather than hidden. ===== .env.example ===== # Copy to .env and document every variable when it is introduced. # Never put real credentials in this file. APP_ENV=development # Add only values required by the selected implementation.

Vibecode SharpAPI
Kinda. The core of SharpAPI is buildable in a weekend with the prompt on this page, but there are real gaps: tuned prompts per use case, tested against messy real-world inputs, response contracts that stay stable when the underlying models change. Read the honest list above before committing.
How much does SharpAPI cost?
SharpAPI costs about $50/month (Build, checked 2026-08-10), which is $600 per year.
What do I lose by replacing SharpAPI?
Honestly: tuned prompts per use case, tested against messy real-world inputs; response contracts that stay stable when the underlying models change; the managed async queue with polling, throttling, and rate limits; ready SDKs for PHP/Laravel, Node, and Python; 80+ language coverage tested per endpoint. If any of those are load-bearing for you, keep paying.
Is there an open-source alternative to SharpAPI?
Yes: OpenAI Node SDK (official client with structured outputs, the engine behind most DIY task endpoints), Instructor (schema-validated structured extraction from LLMs, with retries on invalid output), BullMQ (Redis-backed job queue if the SQLite job table stops being enough). Using prior art is also vibecoding; the prompt is for when you want it exactly your way.
