# Marcus Tran, Senior AI Engineer at Fieldstone Labs (Series B, ~130 people) — read of search-api-optimized-for-ai-agents-that-returns-cu, June 18 2026

> 8 years building backend systems, last 2 fully on agent infrastructure. Currently the person responsible for our LangGraph pipeline that breaks every time a third-party API changes their docs without warning.

## How I got here

Googled "search API for AI agents real-time documentation" after the fourth time this month our ReAct agent hallucinated a deprecated endpoint. Tavily gives me web results but not code-first, version-aware answers. This page showed up around result 6 or 7. Clicked it thinking it was an actual API I could hit with a curl command.

## What I clicked first

"Stop feeding your AI agents outdated docs and SEO spam" got me. That is the exact phrase I used in our internal Slack two weeks ago, almost word for word. So I kept reading.

Then I hit "Code examples, not blog posts" and "Returns working code snippets alongside docs, skipping opinion pieces and outdated tutorials." OK, now I'm reading the integration docs in my head. Where's the endpoint? What's the request shape? What does a response object look like?

It's not there.

## Where I paused

"Honest disclosure: we don't have live customers on this idea yet. We shipped the strategy package; you ship the customer conversations."

I had to re-read that sentence three times. I came here looking for a search API to plug into my agent pipeline. What I'm actually on is a page selling me the *idea* of building a search API. That's not a disclosure buried in fine print -- that's a total category mismatch with what I was searching for, and it's sitting below the fold after a feature table that reads exactly like product documentation.

I'm not mad. It's honest. But it's also strange that the page spends that much time describing API features that don't exist yet as if they're ship-ready.

## What I distrusted

The scoring system. "71/100 Adoptability" with axes like "pain intensity: 10/10" and "buyer clarity: 10/10" but "financial upside: 1/10." I don't know what methodology produced those numbers. "Fermi" is mentioned twice -- $-22,000 Year-1 take-home -- and I'm supposed to just trust that? Who ran the Fermi estimate? What assumptions went in? The score feels like authority-cosplay. A number in a box with no visible math is not the same as transparency.

Also "meaningful-success odds: 1 in 8." That's a confident-sounding fraction. Is that based on comparable SaaS products? Historical outcomes from Wishdeal ideas? The founder's gut? I genuinely cannot tell.

## What would convince me

If this were a real API: one working endpoint I could call right now with a test key, returning a JSON blob. That's it. Everything else is noise until that exists.

If this is an idea I'm supposed to adopt and build: show me one person who adopted a previous Wishdeal idea and has paying customers. Not a testimonial. A company name I can look up. Revenue number doesn't need to be impressive. I just need to know the path from "I bought the $99 package" to "someone gave me money" has been walked before by a real human.

The "financial upside: 1/10" with a negative Year-1 estimate actually builds trust with me in a weird way. That's an honest thing to say. But I need to understand what the upside *could* look like in Year 2 or 3, not just the pessimistic Fermi.

## What I'd ask in an email reply

1. Has anyone bought the $99 adopt package for any of your other ideas and shipped it? Can I talk to them?
2. The feature table describes real-time source ranking and API-native search -- is any of this prototyped, or is the $99 tier literally a Notion doc and a code scaffold that doesn't run yet?
3. You say "pain intensity: 10/10" -- who validated that? Developers you talked to, or developers you observed building agents? There's a difference.

## Verdict: on-the-fence

The underlying pain is real, the honesty about having no customers is unusual in a good way, and "Stop feeding your AI agents outdated docs" is a line that will stick with me. But I showed up looking for an API and found a pitch deck for an API, and that gap needs to be resolved in the first two sentences of the page, not after the feature table.
