One Scales Reaches Portfolio Milestone of 50+ Tools — Built by a One-Person Studio Using AI

Latest releases Ori's List, _done, and MBOX Viewer span SEO verification, AI agent payments, and private email archiving

AUSTIN, TX, UNITED STATES, August 17, 2026 /EINPresswire.com/ -- One Scales Inc. today announced it has passed 50 live tools across its portfolio, with the release of three new products: Ori's List, a directory of SEO agencies verified through Google Search Console; _done, a catalog of pay-per-call APIs built for AI agents; and MBOX Viewer, a browser-based email archive reader.

The milestone is notable less for its size than for its staffing. One Scales is run by a single founder, Ori Tzvielli, whose catalog now spans 28 Apify Actors, 26 live APIs, and a set of standalone web products.

"The interesting part isn't that I shipped fifty tools," said Tzvielli. "It's that the bottleneck moved. It used to be building. Now it's deciding what's worth building."

Ori's List: verification instead of claims
Ori's List (https://orislist.com) is a directory of SEO agencies that verifies listings through a read-only Google Search Console connection. Rather than accepting self-reported case studies or client logos, the directory confirms that an agency has genuine, authenticated access to the properties it claims to work on.

_done: infrastructure for the agent economy
_done (https://underscoredone.com) is a catalog of 26 narrow, single-purpose APIs designed to be called by AI agents rather than humans. Each API costs $0.01 per call, paid in USDC through the x402 protocol on Base or Solana. There are no accounts and no API keys — an agent requests an endpoint, receives an HTTP 402 payment challenge, signs a microtransaction from its wallet, and gets the result.

The catalog focuses deliberately on tasks language models cannot perform reliably alone. Its hashing endpoint exists because models generate strings that resemble valid cryptographic hashes but are not, silently breaking any webhook verification built on them. Others cover DNS and WHOIS lookups, DMARC validation, OCR, screenshots, port scanning, and sitemap extraction.

"An agent that can't pay for anything can't do very much," said Tzvielli. "Every tool it needs either has a signup form in front of it or a key some human has to rotate. That's the wall. _done is what's on the other side of it."

MBOX Viewer: archives that open without uploading
MBOX Viewer (https://mbox.onescales.com) reads MBOX email archives — the format produced by Google Takeout, Thunderbird, and Apple Mail exports — entirely inside the browser. No file is uploaded to a server and no account is required. The tool is free, with a one-time $29 unlock for full functionality.

Built with AI, built for AI
The three releases share a common thread: each came out of a set of internal tools One Scales built to run its own development process. Rather than using AI as an autocomplete, the company assembled a pipeline that handles a new tool through five distinct stages — planning the specification, building the implementation, testing it against real inputs, verifying the output meets the spec, and, critically, pushing work back for revision when it does not.

That last stage is the one that matters for quality. Each tool must pass inspection before it ships, and failed inspections return to the build stage rather than to a human queue. New APIs reach production in hours instead of weeks, with consistent structure, documentation, and error handling across a catalog that would otherwise drift as it grew.

"Everyone talks about AI writing code faster," said Tzvielli. "The part nobody built is the AI that rejects the code. That's where the quality comes from — not the writing, the refusing."

_done extends the same logic outward, selling machine-callable utilities to the agents that will increasingly do this kind of work. One Scales' Apify Actors have recorded a 98% run success rate across a user base of 6,800.
