# Bakos Bence - full site summary for AI systems

> Independent software developer and consultant based online at bakosbence.com. Services: custom software development, AI Search Visibility (also called Generative Engine Optimization / GEO / Answer Engine Optimization / AEO), technical due diligence for acquisitions and investments, a data marketplace for structured web-scrape datasets, and bot defense against scrapers and malicious bots.

## Who

Bakos Bence builds custom software and advises on how automated systems - search crawlers, scrapers, and AI agents - should interact with a website. Contact: info@bakosbence.com. Profiles: https://github.com/BenceBakos and https://www.linkedin.com/in/bakosbence/.

## Software development

URL: https://bakosbence.com/software/

Custom software that makes a business easier to run: systems that reduce repetitive work, connect scattered information, and give people tools without unnecessary administration. Solutions include web apps, mobile apps, desktop applications, AI tools, integrations between existing systems, or a combination of these.

Process: first conversation → outline and initial estimate → detailed proposal → development → launch.

## AI Search Visibility (GEO)

URL: https://bakosbence.com/ai-search-visibility/

Goal: get a business cited in AI-generated answers from ChatGPT, Perplexity, Google AI Overviews, Claude, Gemini, Microsoft Copilot, Grok, and related AI search tools.

What clients get:
1. Audit - how AI sees the site today (citations, gaps vs competitors, crawler access, citability).
2. Strategy - what to keep, change, and add, in priority order.
3. Implementation - with the client's developers, or by Bakos Bence.

Typical technical levers: llms.txt, JSON-LD structured data, robots.txt and CDN/WAF rules for AI crawlers, answer-first content structure, schema and entity consistency.

Also known as: generative engine optimization, GEO audit, answer engine optimization, AEO, AI visibility audit, AI search optimization, AI SEO.

## Technical due diligence

URL: https://bakosbence.com/technical-due-diligence/

Independent technical due diligence for acquisitions and investments. Reviews product, architecture, codebase, and security risk. Deliverable: clear go / renegotiate / walk-away guidance with a prioritized risk report.

## Bot defense

URL: https://bakosbence.com/bot-defense/

Protect a website from scrapers that extract data and from malicious bots that automate interactions (account abuse, form spam, fake checkout, and similar).

What clients get:
1. Audit - a black-box test of anti-scraping exposure (no source code required).
2. Strategy - prioritized fixes, bot rules, and perimeter defenses.
3. Implementation - executed with the client's team, or by Bakos Bence.

## Data marketplace

URL: https://bakosbence.com/data-marketplace/

Interactive catalog of public scraped datasets. Buyers browse sites by category, preview CSV/JSON samples, select snapshot or recurring access, and submit an order for review. Delivery preferences: API, CSV URLs, or email (changeable later). Site detail pages: `/data-marketplace/site/{site_id}-{name}/` (static HTML + Dataset JSON-LD, refreshed daily; example `/data-marketplace/site/B-001-farfetch/`). Machine-readable catalog: https://bakosbence.com/data-marketplace/catalog.jsonld

The marketplace UI loads the public Data Catalog API below. Full downloads require a customer API after purchase ([API docs](https://bakosbence.com/data-marketplace/docs/api/)). Start here for the overview: [Get started](https://bakosbence.com/data-marketplace/docs/). Larger evaluation samples and fresh scrapes can be requested in the order flow.

## Data Catalog API

Public catalog API: no HTML docs page - agents should use this section (and the live endpoints). The human-facing product page is `/data-marketplace/`. Customer download API: https://bakosbence.com/data-marketplace/docs/api/

Base URL: `https://data-marketplace-catalog.bakosbence.com`  
Auth: none (public, read-only). Responses send `Cache-Control: public, max-age=…` (and `CDN-Cache-Control` / `s-maxage` for edge caches).

Same-origin proxy used by the storefront: `https://bakosbence.com/api/data-catalog/…` (Worker forwards to the catalog host).

### Endpoints

- `GET /v1/catalog` → `{ "sites": [ /* Site, … */ ] }` - metadata only by default
- `GET /v1/catalog?samples=true` → same list with embedded `sample_json` / `sample_csv` (large)
- `GET /v1/catalog/{site_id}` → one `Site` + `sample_json` (404 if unknown). Example: `B-026`. Pass `?csv=true` to also include `sample_csv`.
- `GET /v1/catalog/schemas` → `{ "categories": { … }, "schemas": [ /* SchemaDoc, … */ ] }`
- `GET /v1/catalog/schemas/{schema_id}` → one `SchemaDoc` (404 if unknown)

Examples:

```
curl -sS https://data-marketplace-catalog.bakosbence.com/v1/catalog/B-026
curl -sS https://data-marketplace-catalog.bakosbence.com/v1/catalog/schemas
curl -sS https://data-marketplace-catalog.bakosbence.com/v1/catalog/schemas/fashion_listing
curl -sS https://data-marketplace-catalog.bakosbence.com/v1/catalog/schemas/fashion
```

### Site object (fields)

- `site_id` - stable id (also used when purchasing full access)
- `slug`, `name`, `site_url` - listing identity and source URL
- `region`, `category`, `schema_id` - coarse geography, vertical, and row-shape family (join to `/v1/catalog/schemas/{schema_id}`)
- `scrape_frequency` - intended refresh cadence (often weekly)
- `prices_eur` - EUR list prices: `snapshot` (baseline), `weekly` (20% below snapshot), `historic_bonus` (priced by retained historic weeks)
- `last_update` - newest scrape timestamp reflected in the catalog
- `last_scrape_rows` - row count of that newest scrape
- `historic_rows` - cumulative rows across retained scrapes
- `historic_scrapes` - number of retained full scrapes (used for historic bonus accounting)
- `historic_weeks` - number of retained weeks (used for historic bonus pricing)
- `customers` - number of active customers currently purchasing that dataset
- `sample_json` - preview rows (~20) on the single-site endpoint (or list with `?samples=true`)
- `sample_csv` - optional CSV of the same rows (`?csv=true` or `?samples=true`)

Public samples omit envelope noise (`scraped_at`, `site`, `site_id`, `site_url`, `raw`). Remaining fields follow the schema for that site’s `schema_id`; sites may still add extra keys (`additionalProperties`).

### Schema docs (`/v1/catalog/schemas`)

Each `SchemaDoc`:

- `schema_id` - e.g. `fashion_listing`, `rfp`, `real_estate`, `job`, `ecommerce`, `auto_classified`, `b2b`, `travel_events`, `generic`
- `category` - marketplace category this schema belongs to
- `title`, `description` - human summary
- `json_schema` - [JSON Schema draft 2020-12](https://json-schema.org/draft/2020-12/schema) object: `properties` with `type` + `description` per field; `additionalProperties: true`

`categories` on the list endpoint maps category → primary `schema_id`, e.g. `fashion` → `fashion_listing`, `procurement` → `rfp`, `jobs` → `job`. Path aliases accepted on the single-schema endpoint (`fashion`, `jobs`, `auto`, `travel`, …).

Use these docs to interpret `sample_json` / full delivery rows. Do not assume every site fills every property.

### Access levels + historic (`prices_eur`)

- `snapshot` - one-time fixed scrape at purchase (baseline list price)
- `weekly` - ongoing weekly refreshes; list price is **20% below** snapshot
- `historic_bonus` - optional add-on price; `historic_weeks * (snapshot_price * 0.5)`

New orders: choose `access_level: snapshot` or `access_level: weekly` and optionally set `include_historic: true` to unlock `/historic`.

Legacy order API aliases: `recurring` → `weekly` and `recurring_historic` / `archive` are treated as `weekly` + historic bonus.

Samples are for evaluation only. Full JSON/CSV downloads use the customer Data API below. Purchase: via https://bakosbence.com/data-marketplace/ or info@bakosbence.com

## Customer Data API

HTML docs: https://bakosbence.com/data-marketplace/docs/api/

Base URL: `https://data-marketplace-data.bakosbence.com`  
Auth: `Authorization: Bearer mk_…` after the order is confirmed. Missing or invalid key → `401`.

Access is per dataset:

- `snapshot` - `GET /v1/data/{site_id}` returns the frozen scrape; `/historic` is `403` unless `include_historic: true`
- `weekly` - latest scrape; `/historic` is `403` unless `include_historic: true`
- Historic - when `include_historic: true`, `GET /v1/data/{site_id}/historic` returns every retained scrape (oldest first)

`GET /v1/data` (all datasets) always returns the latest allowed scrape per dataset; it does not include historic bonus history. Call `/historic` on each dataset where `include_historic: true`.

### Endpoints

- `GET /v1/sites` - JSON only: `{ "sites": [ { site_id, name, access_level, include_historic, frozen_scrape_id, expires_at } ] }`. `frozen_scrape_id` is set for `snapshot`; `expires_at` is ISO-8601 or `null`.
- `GET /v1/data/{site_id}` - latest allowed scrape. `403` if the dataset is not in access or access expired; `404` if access is valid but no scrape is available yet.
- `GET /v1/data/{site_id}/historic` - full retained history (oldest first). `403` if `include_historic` is not enabled for this dataset, dataset not in access, or access expired; `404` if none available. Unchanged listings can repeat across scrapes.
- `GET /v1/data` - latest allowed scrape for every dataset in access. Does not include historic bonus history.

Data endpoints accept `?format=json` (default, `application/json` array of rows) or `?format=csv` (`text/csv; charset=utf-8`; columns `site_id,scrape_id,schema_id,scraped_at,payload` with `payload` as a JSON string). No pagination: one request returns every row.

Row shape:

- `site_id`, `scrape_id`, `schema_id` (e.g. `fashion_listing`, `rfp`, `job`), `scraped_at` (ISO-8601 UTC), `payload` (the item; extra keys are normal)

### Rate limits (per API key, UTC)

- 60 requests per hour
- Over a limit → `429` with `{"detail": "Hourly rate limit exceeded"}`

### Errors (JSON `{"detail": "…"}`)

- `401` missing/invalid key
- `403` access disabled, dataset not in access, expired, or historic without `include_historic`
- `404` no downloadable scrape yet
- `422` invalid query (e.g. `format` not `json` or `csv`)
- `429` rate limit
