Can I vibecode SharpAPI?

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.

the prompt
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.

why people still pay

Because they need five of these workflows, not one, and someone else keeps the prompts, schemas, and model choices working while they ship their actual product. A team that only needs one endpoint is exactly who should DIY it.

questions
Is SharpAPI free?

14-day trial with 100,000 processed words, no credit card. Paid is Build at $50/mo (checked 2026-08-10).

Can I 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.
