Give your AI agents structured web data

We build managed API endpoints on top of any website. Your agents call our API, get clean JSON back, and never deal with HTML parsing or site changes.

Sub-second response times. We handle uptime, adaptation, and scaling.

Trusted by 300 public and private organizations.

How Website-to-API works

AI agents need structured data, but most of the world’s information lives on websites without APIs. We build lightweight API layers on top of target websites. Your agents get deterministic, accurate JSON every time, with none of the fragility of direct scraping or LLM-based parsing.

Structured JSON from any website

Clean, typed output. No HTML parsing on your side. Schema designed together with your team.

Automatic site adaptation

When source websites change their layout, we update the API. Your agents keep working.

Sub-second responses

Cached and optimized for real-time agent queries. Faster than scraping on every call.

Rate limiting and auth built in

We handle rate limits, authentication, and retries. Your agents see a clean REST endpoint.

What most teams try first

Direct scraping inside agent code

The appeal

Your agents already make HTTP requests. Add a parser and you own the whole stack.

Where it breaks

Works until the site changes layout, adds bot detection, or your agent hits rate limits at 2am. Maintenance becomes a recurring engineering tax.

LLM-based page parsing (send HTML to GPT)

The appeal

No brittle selectors. The model figures out the structure.

Where it breaks

LLMs hallucinate field values, miss records, and cost 10-50x more per query than a purpose-built endpoint. Not viable when your agents need deterministic, accurate data.

Built for these situations

Teams building AI agents that need real-time data from websites without APIs
Companies running price monitoring, lead enrichment, or competitive intelligence agents
Engineering teams tired of maintaining fragile scraping code inside their agent pipelines
Organizations that need deterministic data extraction, not probabilistic LLM parsing

Tell us which websites your agents need

We’ll design the API schema together and have a working endpoint within days.

Factors: number of source websites, output schema complexity, query volume, and site anti-bot measures.

From website to API in days

01

Identify sources

Tell us which websites your AI agents need to access. We assess feasibility and data structure.

02

Design schemas

We design the JSON output format together. You define what your agents need, we map it to the source.

03

Build and deploy

We deploy a managed API endpoint for each source. Typical build time is 3 to 5 days per source.

04

Integrate

Your agents call our REST API like any other data source. Standard authentication, documented endpoints.

05

Monitor and adapt

We handle uptime monitoring, site change detection, and automatic adaptation. You get alerts, not outages.

Why teams choose Stratalis for Website-to-API

Scraping is our core discipline

We’ve built hundreds of production scrapers. Anti-bot systems, JavaScript rendering, dynamic content. All routine for us.

Deterministic, not probabilistic

LLMs hallucinate field values and miss records. Our APIs return accurate, typed data every time.

You talk to engineers

No account managers. The people designing your API are the people building it.

We own the maintenance

When sites change, we fix the API. You don’t get paged at 3am because a CSS selector broke.

FAQ

One endpoint per source website. If you need data from 5 sites, you get 5 endpoints with a consistent schema across all of them.

We detect layout changes automatically and update the extraction logic. Your API contract stays the same. Typical adaptation time is under 24 hours.

Tell us which websites your agents need

Share your target sites and data requirements. We’ll scope the API within 48 hours.
