Comparison
Ways to get this data
Three approaches teams use today, and where each one runs into trouble.
| Approach | What it takes | Cost | Trade-off |
|---|---|---|---|
| Y Combinator directly | Open the page on Y Combinator and read it | Free, and slow | Fine for one record, useless across a list, and the layout differs on every platform |
| Building a scraper | Write it, host it, and repair it when Y Combinator changes its pages | Engineering time | A maintenance commitment for something that isn't your product |
| NeuralVerge | One request, the same shape as every other source in the catalog | $5 per 1,000, misses not billed | Returns what Y Combinator publishes at request time. Other platforms are separate sources with the same request format |

How to run it
The same lookup works from the app, the API, or as a tool an agent can call mid-task.
One record per request. Results come back in the same envelope as every other source: a session id, a readable summary, the structured result and the points charged.
curl -X POST https://api.neuralverge.ai/functions/v1/run-yc-companies \
-H "Authorization: Bearer YOUR_API_KEY" \
-H "Content-Type: application/json" \
-d '{"company":"airbnb"}'Use cases

- —Funding rounds and valuation are not part of the directory page.
