API Overview

Status: Limited

The T-Suite marketplace API is the API that Libertum’s own web apps use. It is not yet a supported public product: there is no published, maintained OpenAPI reference, and paths and fields can change between releases. Use this page to understand the shape of the API; agree any integration with Libertum before building on it. A public OpenAPI reference is planned.

Base path and hosts

All marketplace API routes are served under the base path:

/marketplace/v1

on the T-Suite API host for your deployment. The host is provided as part of an integration arrangement.

Requests and responses are JSON over HTTPS, except file uploads (multipart) and the real-time notification stream (Server-Sent Events).

Route groups

Group	Prefix	Authentication
Account	sign-up, sign-in, code verification and password reset at the root of the base path	None (these routes create the session)
Authenticated	/auth/...	User access token — see Authentication
Other authenticated groups	orders, dividends and subscription management have their own prefixes	User access token
Public	/public/...	None — read-only data that is already public, plus a few token-gated flows
Stablecoin developer API	/api/stablecoin/v1	Issuer API key

Most product routes behind /auth/... also pass the onboarding gate, and paid products additionally check the subscription module.

Resource groups

The main resource groups, by product area. This is a map, not an endpoint reference.

Investing and offerings

Resource group	Purpose
Offerings	Create, configure, deploy and list offerings; offering documents; Coming Soon listings and interest
Orders	Primary subscription orders and their payment rails (card, bank wire, USDC/USDT via Escrow)
Agreements	Agreement templates, investor signature specimens, signing, executed PDFs and audit trails
Dividends	Dividend distributions to token holders
Transfers	Token transfer requests and the transfer journal
Secondary market (P2P)	Peer-to-peer order book for listed tokens
Redemptions	Redemption windows, redemption requests and investor payout accounts
Governance	Proposals and investor voting
Investor statements	Investor summary and combined transaction feed
Holdings	A user’s token holdings

Accounts and billing

Resource group	Purpose
Profile and security	Profile, password, two-factor authentication and backup codes, sign-out
KYC / KYB	Identity-verification sessions and status (via SumSub)
Subscriptions	Plan and module catalogue, checkout, plan changes, add-ons, billing portal
Issuer team	Inviting team members and managing roles
Issuer billing and payments	Issuer invoices, payment settings, bank accounts and saved payment methods
Linked wallets	External wallets a user has connected
Country restrictions	The platform’s country grey-list and black-list
Support	Support tickets and disputes

Wallets and payments

Resource group	Purpose
Custodian Wallet	Balances, deposit details, saved withdrawal addresses and withdrawals
Gas treasury	Prepaid gas balance and network-fee charges for custodian transactions
T-Pay	Fiat on/off-ramp via Bridge.xyz (limited availability)

Distribution, structuring and other products

Resource group	Purpose
Distribution Hub	Investor CRM, AI matching, campaigns, pipeline, communications and Libby AI features
Hosting	Cross-marketplace hosting requests and the Ecosystem Directory
Structuring	Structuring projects, intake, research, document generation, artefacts and guest review links
Trading	Paper-trading accounts, signals and the Discover feed
Stablecoin Studio	Stablecoin configuration, mint and redeem orders, and the minter portal
Whitelabel	Tenant branding and custom-domain settings
Asset Management	Assets, portfolios, clients, work orders, tags, compliance items, reports and migration
Notifications	In-app notifications and the real-time stream — see Real-time & webhooks
Accreditation	Investor accreditation evidence (coming soon — not yet reviewed)
XRPL platform	XRPL infrastructure (not yet selectable by issuers)

Public routes cover data that is already visible on public pages — a public offering view and its NAV history, the country restriction lists, tenant branding, the platform fee, Distribution Hub investor self-registration, and the Structuring guest review page that outside counsel opens from a share link.

Token metadata. ERC-721 token metadata is served at a separate, permanent path outside /marketplace/v1, because that URL is written into token contracts and must never change. It resolves only for approved, deployed ERC-721 offerings.

Response format

Responses use a single envelope:

{
  "message": "Human-readable message",
  "status": 200,
  "data": { },
  "error": false
}

• error is true on any failure, and status repeats the HTTP status code.
• data carries the payload on success. On some failures it carries machine-readable detail — for example requiresOnboarding and missingStep from the onboarding gate, or reason and moduleId from a subscription check.
• Branch on status and on fields in data, not on the message text, which can change.

Exceptions: the real-time stream sends Server-Sent Events, and token metadata returns raw ERC-721 metadata without the envelope.

Status codes

Status	When you will see it
200 / 201	Success
400	Validation failed or the request is not allowed in the current state
401	Missing, invalid, expired or superseded access token
402	The account does not have the subscription module this product requires. data.reason names the case (for example, not subscribed versus a lapsed subscription that is now read-only) and data.moduleId names the module to add
403	Signed in but not allowed: 2FA step pending, onboarding incomplete, wrong role or persona, or a blocked account
404	The route or resource was not found
409	Conflict with existing data, such as a duplicate
429	Rate limit reached
500	Unexpected server error
503	A dependency, such as the session store, is temporarily unavailable — retry with backoff

Products that answer 402 today include Distribution Hub, Libby AI features, Structuring, Trading and Stablecoin Studio. A lapsed Structuring subscription keeps read access and answers 402 only on write actions.

Rate limits

Rate limits apply to specific sensitive routes — for example, requesting withdrawal verification codes, the public Structuring review page, and the Stablecoin developer API (300 requests per minute per client). When a limit is reached the API answers 429; limits are advertised in standard RateLimit-* response headers where they apply. Clients should back off and retry rather than hammering a route.

Stablecoin Studio developer API

Status: Limited

Stablecoin Studio issuers have a small, read-only developer API at /api/stablecoin/v1:

• Authentication: an issuer API key, created and revoked on the Developer page in Stablecoin Studio, sent as a Bearer token or in an API-key header.
• Scope: each key reads only its own issuer’s data — tokens, mint orders, redeem orders and API usage — plus a connectivity check.
• No writes: creating mint orders and other changes stay in the Stablecoin Studio app.
• Billing: API usage is metered per issuer; billing for developer API usage is coming soon.

OpenAPI reference

A maintained public OpenAPI reference is planned. Until it is published, treat this page as the authoritative description of the API’s shape, and request endpoint-level detail from Libertum as part of an integration agreement.
