As answered by people managing YieldStack and Bewary.
YieldStack's answer
The largest CRE Lenders in the USA
Bewary's answer:
The API launched on 1 November 2026, and there are no customers to name yet.
YieldStack's answer
AI integrations supporting the platform’s workflows.
Bewary's answer:
Python with FastAPI and PostgreSQL behind the API, a remote MCP server over streamable HTTP with OAuth 2.1 sign-in, a Node.js CLI published on npm as bewary, and an Astro website.
YieldStack's answer
YieldStack combines AI-assisted lender matching with hands-on commercial mortgage brokerage. Borrowers submit once, compare financing options, and work with a team that handles structuring, negotiation, and closing coordination. Borrowers approve lender outreach, with no upfront fees and a broker fee paid only at closing.
Bewary's answer:
Bewary answers from evidence, not from a language model. Each lookup returns a verdict (scam, suspicious, safe or unknown), the probability that it is a scam, the facts behind it and reason codes your code can branch on, and unknown is never safe. One key covers links, domains, IP addresses, phone numbers, SMS short codes, email addresses, crypto wallets, IBANs, mobile apps and payment handles, through a REST API, a remote MCP server for AI agents and a CLI.
YieldStack's answer
YieldStack helps borrowers evaluate the whole financing offer: rate, leverage, fees, reserves, prepayment terms, and closing requirements. Its platform organizes the process, while its brokerage team helps borrowers find suitable lenders and move the deal forward. One submission gives borrowers a coordinated financing process without an upfront brokerage fee.
Bewary's answer:
One key and one typed response format cover ten kinds of input, so an app or an agent does not stitch together a URL API, a phone API and a wallet screening service. Bewary also answers questions few APIs do: which company operates a US SMS short code, the FTC and FCC complaints behind a phone number, and whether Tether or Circle froze a wallet. Commercial use is allowed, and a free key gets 1,000 credits a month with no card.
YieldStack's answer
Commercial real estate investors, developers, operators, and mortgage brokers seeking bridge, DSCR, fix-and-flip, construction, multifamily, and permanent financing across the United States.
Bewary's answer:
Developers who add a link, phone number or email check to an app; builders of AI agents that need to check a link, number or payment before acting; trust and safety and fraud teams screening sign-ups, sellers and payouts; and security teams loading a scam domain feed into a DNS resolver or a threat intelligence platform.
YieldStack's answer
Rommin Adl and Daniel Chesney founded YieldStack to simplify commercial real estate financing. The platform brings deal preparation, lender matching, offer comparison, and closing coordination into one workflow, combining AI-assisted analysis with human brokerage expertise.
Bewary's answer:
Bewary started as a consumer scam checker. The engine behind it, built on public complaint data, threat feeds, certificate transparency logs and its own DNS history, turned out to be what businesses and AI agents need, so since November 2026 Bewary is an API, an MCP server and a CLI.
