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.

# 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.

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.

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.
