Every check your business runs — sign-in, real person, age, identity, consent — answered with a signed proof instead of a document. You get trust, never custody.
By industry
01Financial services
KYC you can rely on, without the document vault
Onboard customers on a KYC-grade check and identify any of them the moment something warrants it — with a signed request and a stated reason. You hold access to identity, not a copy of it.
TodayWith Leagle.id
A per-check KYC fee for every customer you onboard
A person verified once arrives verified — no new check, no new fee per customer
A bucket of passports and selfies to secure, retain and delete
No identity documents stored; a breach can’t expose what you never held
A deepfaked executive on a call can talk finance into wiring money
Payment instructions arrive sealed by a verified person — a fake carries no valid seal
Players prove they are old enough in one tap, and one person is one account. You keep a signed proof of every check for your regulator — not a birthdate you never needed.
TodayWith Leagle.id
Players abandon at the ID upload and the selfie
One approval in the wallet; the answer is a signed “older than 18”
Bonus abuse and multi-accounting through fresh sign-ups
One person, one Holder ID at your service — a duplicate shows up as the same player
Dates of birth and ID scans of minors in your database
Proof of the check without the data behind it
Age check
Real-person check

03Travel & mobility
Bookings from AI agents, with a verified traveller behind each one
Your guests’ assistants already search for flights, rooms and cars. Accept their bookings on a budget the traveller signed, take payment with your own checks, and sign a receipt for each sale.
TodayWith Leagle.id
Agents blocked as bots — and the booking goes to whoever accepts them
An agent presents a certificate: your line, the option, the cap the traveller approved
Agents logging in with the traveller’s password and card
Agents never hold a password or a card; each line is accepted once per plan
Passport details retyped for every booking
Ask for the claim you need — a valid licence for category B, residence in the EU
Sell to your customers’ agents, and win the dispute after
One standard endpoint for every AI agent, not an integration per vendor. Every agent purchase sits inside a plan the customer signed, so “I didn’t order this” has an answer.
TodayWith Leagle.id
Chargebacks you lose for lack of evidence
The presented certificate and your signed Sale Receipt show exactly what was approved
Promo, trial and referral abuse by duplicate accounts
Bans stick: a banned person can’t return as a new account
Card details in your systems and a wide PCI scope
The customer signs a Payment Instruction a licensed provider executes
Real people on your platform, and nothing to leak about them
Every account is backed by a verified, unique person — disclosed to you only as a pseudonym. Meet age-assurance rules without holding minors’ data, and know which delegate acted when something goes wrong.
TodayWith Leagle.id
Fake sign-ups, bots and ban evasion
A bot can’t pass the one-time verification; a returning person is the same Holder ID
Age assurance under the DSA or the UK Online Safety Act means collecting IDs
A signed claim per check — kept as evidence you can show an auditor
Abuse from an account you can’t attribute
Ask the person to account for which delegate did it; escalate to identity if they don’t
No passwords, no per-user identity bill, no shared API keys
Your users sign in with a key they hold; you verify offline and keep your own sessions. Assistants, accountants and agents get scoped, expiring access instead of someone’s password.
TodayWith Leagle.id
A password database, reset e-mails and lockout tickets
Nothing to leak, stuff, phish or reset — a signature over your fresh challenge
An identity provider billing per active user, and sitting in your login path
Leagle.id is never in your login path: certificates verify against a public key
Customers share passwords and personal API keys with their assistants
Each delegate gets its own link with only the rights it needs, until a set time

07Professional services
Consent you can prove, from clients you know are real
When a client later says “that wasn’t me”, a checkbox shows someone clicked. A Sign-off proves who agreed, to exactly what, and when — signed by a verified person.
TodayWith Leagle.id
“I agree” checkboxes and confirmation e-mails as your evidence
A non-repudiable signature over the exact terms, kept by you
An e-signature fee for every simple consent
Sign-off on contracts, payments and settings changes — part of the same integration
Accountants and assistants logging in as the client
Delegated access that can only narrow, recorded under its own pseudonym

Any industry
One integration, then every check is a different question
One verification per person backs every level. Start with sign-in, then ask for more exactly where you need it.

02Real-person checkA real, unique person
03Age check“Older than 18”, nothing more
04KYC on demandIdentity on a signed request
05Sign-offWho agreed, to what, when
Never in your path
You verify certificates offline against Leagle.id’s public key. It sits in neither your login nor your checkout.
No cutover
Every check runs next to what you have today. Retire the old vendor when its share no longer justifies its cost.
Verified once, everywhere
One verification per person backs every check. Someone verified for another service arrives verified at yours.
Trust, never custody
You receive signed answers, not the data behind them — unless the person hands it over, visibly and revocably.
A pseudonym per service
Nobody, Leagle.id included, can link one person across services. Your users can’t be profiled through you.
Money stays licensed
Banks and licensed providers hold and move money. Leagle.id only carries the person’s signed instruction.
Evaluate it yourself
Ask your own agent what it means for you
Your agent gets facts to reason with, not a pitch: the problems a service may have, what to look for in your code, the objections and how to migrate. It matches them to what you actually run and offers a Migration Overview you can share.
