Proof Launches x401, the Open Protocol for Verifying the Authority Behind AI Agents

Published

on

Developed by Proof with contributors across payments, identity and AI, x401 lets any online service request proof of who authorized an agent’s actions. Live demos and a CLI are available today.

BOSTON, June 25, 2026 /PRNewswire-PRWeb/ — AI agents can now buy, sign, build, publish and move money. What they can’t carry is proof of who authorized the agent.

“AI is making actions and content effortless to generate. Trust will come from knowing who stands behind them. x401 gives every service a common way to ask for proof. Proof Digital ID gives people and organizations a high-assurance signed record of who authorized what.” – Pat Kinsel, CEO of Proof. “

Every company is racing to open its products to AI. The hard part isn’t getting agents to act; it’s trusting that a real person authorized them. Without that, a service has no safe way to let an agent through.

Today, Proof, the identity authorization company, launched x401, an open, issuer-neutral protocol that lets any website or API ask for and verify the identity behind agents.

With x401, a service can ask for the proof it requires: verified identity, age, membership, organizational affiliation, signing authority, proof of humanness, orf another trusted claim. The agent presents a compatible credential and authorization. The service verifies the issuer, claim, scope and action before proceeding.

Identity establishes who or what an agent represents. Authorization establishes what it is permitted to do. x401 binds the two into proof and unlocks agents’ ability to act on people’s behalf.

Open by design
x401 is an open protocol allowing any conforming issuer to deliver x401-compatible credentials. Any agent can present them. Every service determines which claims, issuers and levels of assurance it will accept.

That separation allows one protocol to support many forms of authority without forcing the internet to adopt a single identity provider or credential model.

x401 was developed by Proof with technical contributors from leading payments, identity and AI organizations. The public specification, implementation materials, and complete contributor list are available at x401.id.

Proof will submit x401 to the FIDO Alliance’s agentic authentication standards workgroup.

Built to complete the agent stack
x401 is designed to work with the protocols already emerging around agentic activity. In payments, x402 enables machines to make payments. AP2 and Verifiable Intent capture instructions and approvals in commerce. x401 now completes the missing link, when used together with these other protocols, agents can now pay, prove a person’s identity, and authorize specific actions.

“x402 is the open standard that lets agents pay for web resources over HTTP with pay-per-request settled in stablecoins, with no accounts or API keys. Through Circle Agent Stack and USDC, which settles nearly all x402 volumes, Circle has been one of its core contributors. x401, built with Proof, pairs that with identity: x402 answers how an agent pays, x401 answers who it is. Those are the first two questions any agentic transaction has to clear, and now each has an open standard. Circle is proud to be an early adopter and co-endorser of x401.” — Gagan Mac, VP Product, Circle

Proof’s digital identity: A high-assurance identity that can sign
Proof is launching the first live implementation that can satisfy an x401 challenge. Proof’s digital identity is one of the first inline implementations of OID4VC Issuance and Presentation, allowing people to verify their identity to an IAL2 standard and enroll just-in-time or instantly reauthenticate with a biometric. Developers simply request identity and Proof manages the complexity of who is enrolled vs not.

Using selective disclosure and zero-knowledge proofs, someone can prove that they are verified, their nationality, over a required age or authorized to represent an organization without exposing their complete identity record.

In addition to credential presentation, Proof’s platform is the first to support transaction signing, which produces verifiable records. The API supports signing authorizations like AP2 with Verifiable Intent and cryptographically binds a verified identity to any payment, transaction, or payload. Verifiable records prove who you are and what you’ve authorized, creating the evidence that every industry requires in the agentic era. U.S. law has recognized agreements made by electronic agents for decades. Proof provides what’s been missing: trustworthy proof of the person behind the transaction.

Proof’s digital identity is backed by Proof’s Kantara-certified NIST IAL2 identity service and WebTrust-audited certificate-authority infrastructure. As a Certificate Authority that pairs a publicly trusted, audited certificate hierarchy with IAL2-grade identity proofing, Proof’s digital identity is the only legal credential that can secure everything a person signs, does in person, does online, or delegates to an agent.

x401 works end-to-end today
The documentation for x401 is live today. The public specification, technical documentation, sample apps, and contributor list are available at x401.id.

Proof Digital ID documentation is available at dev.proof.com. Developers can connect Proof’s live x401 MCP server to Claude and ChatGPT to use x401 in real agent workflows. Participating organizations will announce their implementations as they become available.

Proof is the identity authorization company that verifies people and organizations, issues high-assurance cryptographic credentials and creates tamper-evident evidence of what they authorize—whether they act directly or through AI agents. Proof has secured more than $640 billion in transactions for 10,000 organizations, including 16 of the Fortune 100. Learn more at proof.com.

From boots to bookings: Mastercard insights show where Calgary Stampede drives meaningful lift for local businesses

Published

on

By

The Mastercard Economics Institute shows restaurants, retail and accommodations are among the biggest beneficiaries.

CALGARY, AB, June 25, 2026 /CNW/ – New insights from the Mastercard Economics Institute (MEI) show the Calgary Stampede does more than draw crowds, it sets Calgary’s economy in motion even before the gates open, from last-minute retail runs ahead of opening weekend to surging restaurant demand and early hotel bookings downtown.

Using aggregated and anonymized spending insights from 2025, alongside travel trends through bookings made by the end of May 2026 with departure dates from June 29 through July 12 for Calgary International Airport, MEI examined how economic activity around the Calgary Stampede compared with expected baseline levels without the event.

MEI estimates that the 2025 Calgary Stampede generated an approximate 18 per cent lift in spending at local merchants relative to baseline, with restaurants experiencing one of the strongest lifts at roughly 29 per cent. Retail spending also surged ahead of opening weekend, while accommodation demand built early, especially in downtown Calgary.

The data reveals a clear pattern: Stampede’s economic impact builds in waves. Retail spending jumps before the festivities begin, as Calgarians and visitors prepare for the week ahead. Dining demand remains elevated through the event, and accommodation spend is front-loaded into the first few days as visitors arrive and settle in. Together, the insights show that Stampede is not just busy, it is an engine of local spending in ways that are visible across time, place and category.

The spending story is also being shaped by international interest in Stampede. Preliminary booking data suggests international travel tied to Stampede is up year over year in 2026, with some of the strongest international growth coming from the United States, Belgium, the Netherlands, Great Britain and Australia.

“The Calgary Stampede is a great example of how a cultural moment can also be a major economic catalyst,” said Benjamin Jacob, Senior Vice President, Services, Mastercard, Canada. “For local businesses, success during Stampede is not just about being busy, it is about being ready. Insights like these can help businesses better anticipate demand and make smarter decisions around staffing and inventory during one of Calgary’s most important economic moments.”

“While the Calgary Stampede is a cultural and recreational highlight for our city, it is also a key opportunity to showcase Calgary on the global stage. The 10-day event reflects the energy, entrepreneurial spirit and community pride that defines Calgary, while attracting visitors from around the world,” said Melanie McDonald, Vice President, Strategic Initiatives, Partnerships and Engagement, Calgary Chamber of Commerce. “Generating an estimated $664 million in economic activity in Calgary in 2025, the Stampede provides a significant boost to restaurants, bars, hotels, entertainment venues, coffee shops, retailers and many other local businesses across the city. It is also a time when Calgary’s business community comes together to strengthen relationships and celebrate the spirit of collaboration that supports the city’s continued growth.”

The insights show how Stampede spending unfolds across the city:

MEI estimates that the 2025 Calgary Stampede drove a roughly 18 per cent lift in overall spending at local merchants relative to expected baseline without the event.Restaurants saw some of the strongest lift in spend, approximately 29 per cent, underscoring the role dining plays in the Stampede experience.Retail spending surged on the Thursday ahead of opening weekend, as consumers prepared for Stampede festivities.Accommodation demand built early, with the strongest lift concentrated downtown in the first few days of the event.Among international markets tied to Stampede travel in 2026, the United States accounts for roughly one-third of all bookings.Travel bookings are up year over year from international markets, including the Netherlands, Belgium, Great Britain and Australia.  

The insights also show that economic value is not evenly distributed. Spending patterns varied by sector, location and timing, with some of the strongest lifts concentrated in areas closest to the Stampede grounds and in experience-led categories such as dining and accommodations.

As businesses navigate a more complex economic environment, understanding those patterns matters. Through the Mastercard Economics Institute and its economic solutions, Mastercard helps businesses, governments and partners decode what is happening in the real economy using anonymized spending insights to help them plan with greater confidence and act on emerging opportunities.

Days After Launch, Attunio Health Expands Precision Psychiatry Infrastructure with Quest Diagnostics and Getlabs

Published

Quest Diagnostics and Getlabs strengthen Attunio’s AI-powered, biomarker-driven infrastructure with blood and genetic testing from home

ATLANTA, June 25, 2026 /PRNewswire/ — Just days after publicly launching its AI-powered precision psychiatry platform and gaining early media attention, Attunio Health announced a major expansion of its clinical infrastructure by selecting Quest Diagnostics as its national laboratory backbone and integrating Getlabs for at-home blood collection.

The announcement marks another significant milestone in Attunio’s rapid growth as the company builds what it believes is the future of mental healthcare: continuous, objective, data-driven care powered by artificial intelligence, biomarkers, and real-world patient signals.

While traditional psychiatry has long relied on subjective symptom reporting, episodic visits, and trial-and-error medication management, Attunio is building a fundamentally different model.

The firm’s system merges:

Clinical insights provided through artificial intelligence.

Physiological information collected by devices worn on the human body.

Examination of blood biomarkers

Examination of genetic material.

The observation of behavior.

Medical professional-directed therapy enhancement.

This infrastructure powers what Attunio calls Closed-Loop Precision Psychiatry™ — a model in which psychiatric treatment is continuously informed by evolving biological and behavioral data rather than limited to occasional appointments.

With Quest Diagnostics serving as Attunio’s national laboratory backbone, the platform can support scalable access to advanced diagnostic testing across the United States.

These diagnostic capabilities help clinicians identify biological contributors to mental health impairment, including:

Impaired metabolic function

Persistent inflammation

Lack of essential vitamins and nutrients.

A state of disrupted hormonal equilibrium.

Drug processing and indicators of safety.

Measures of neurobiological performance

Attunio has also integrated Getlabs to enable blood and genetic testing from home, allowing certified mobile phlebotomists to travel directly to patients’ homes or workplaces for specimen collection.

This dramatically reduces friction in diagnostic testing and makes biomarker-driven psychiatric care more accessible to patients nationwide.

By combining diagnostic testing with wearable data and AI analysis, Attunio aims to help clinicians answer critical questions traditional psychiatric visits often cannot:

Is declining focus caused by ADHD progression or poor sleep?

Is worsening anxiety linked to physiological stress or metabolic dysfunction?

Is medication underperforming due to biology, genetics, or adherence?

Can deterioration be detected before a patient reaches crisis?

As interest accelerates around AI in healthcare, digital biomarkers, and precision medicine, Attunio is positioning itself at the intersection of psychiatry, diagnostics, and artificial intelligence.

The company believes mental healthcare must evolve beyond reactive care.

The future, Attunio says, will be:

Predictive. Measurable. Personalized.

This latest infrastructure expansion builds on Attunio’s recent launch, which introduced a new model of behavioral healthcare centered on wearable data, biomarker analysis, and AI-powered clinical intelligence designed to improve outcomes for conditions such as ADHD, anxiety, depression, and cognitive burnout.

About Attunio Health

“Attunio Health is deeply committed to advancing health and wellness, striving to deliver innovative solutions that make a tangible difference in people’s lives every day. Our dedication extends beyond mere treatment, focusing on proactive care and fostering healthier communities across the region and beyond.” To learn more visit https://www.attuniohealth.com/marketplace
