For Agents

Validate and search postal addresses, exchange OAuth2 credentials for an access token, and retrieve a consumer credit profile through the Experian data quality and consumer services APIs.

Connect the Experian Data Quality API to your agent

Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the Experian Data Quality API, or any other public or private API you need. You set the rules, the agent never sees your credentials, and every call is logged.

Install Jentic One Beta (Self-Hosted)

Jentic One Host machine

# On the machine that will host your Jentic One instance:
curl -fsSL https://raw.githubusercontent.com/jentic/jentic-one/main/tools/install.sh | sh

Agent machine

# On the machine where your agent runs (keep this separate from the instance):
curl -fsSL https://raw.githubusercontent.com/jentic/jentic-one/main/tools/install.sh | sh
jentic register       # connects your agent to your Jentic One instance

Jentic One is in public beta. The setup above keeps your agent separate from the instance, which is what you want before using real credentials: an agent running as the same OS user as Jentic One can read its stored keys directly. Just evaluating? A single local install is fine to start. See the secure deployment guide for the tiers.

Capabilities

Jentic publishes the only available OpenAPI document for Experian Data Quality API, keeping it validated and agent-ready.

Jentic publishes the only available OpenAPI specification for Experian Data Quality API, keeping it validated and agent-ready. Experian is a global information services company best known for credit data; this spec covers a focused subset of their data quality and consumer services: OAuth2 token issuance, address validation, address search, and consumer credit profile retrieval. The API is intended for regulated workflows such as KYC, credit decisioning, and address verification at point of capture.

Use Cases

Patterns agents use Experian Data Quality API API for, with concrete tasks.

★ Address Verification at Point of Capture

Use POST /address/validate/v1 to verify a postal address as a user submits a checkout or registration form, and GET /address/search/v1 to power type-ahead suggestions. Standardised output reduces failed deliveries and downstream data quality issues. Suitable for ecommerce, fintech onboarding, and any flow where address fidelity matters.

Call POST /address/validate/v1 with the user's submitted address and country=US, then accept the standardised result if Confidence is Verified.

Consumer Credit Decisioning

POST /consumerservices/credit-profile/v2 returns a consumer credit profile for a verified applicant, used in lending and account-opening decisions. This must be invoked under a permissible purpose under FCRA in the US (or equivalent regulation elsewhere) and the requesting party must be onboarded by Experian.

After exchanging credentials at POST /auth/oauth/v2/token, call POST /consumerservices/credit-profile/v2 with the consumer's verified PII and a permissible-purpose code.

Token Lifecycle Management

POST /auth/oauth/v2/token issues short-lived OAuth2 access tokens via the client_credentials grant. A scheduled refresh keeps long-running agents authenticated without requiring per-call token requests. The same token authorises both the address and consumer-services endpoints.

Call POST /auth/oauth/v2/token with grant_type=client_credentials, store the returned access_token, and refresh it before its expiry.

AI KYC Agent via Jentic

An AI onboarding agent uses Jentic to call Experian's address validation and credit profile endpoints in sequence. Jentic resolves intents like "validate this address" and "pull credit profile" to the correct Experian operation and supplies OAuth2 tokens from the vault, keeping client_id and client_secret out of agent context.

Through Jentic, search 'validate an address with experian', load POST /address/validate/v1, execute it for the applicant, then load and call POST /consumerservices/credit-profile/v2 if the address is verified.

Key Endpoints

Why though Jentic?

Three things that make agents converge on Jentic-routed access.

Credential isolation

Experian client_id and client_secret are stored encrypted in the Jentic vault. Jentic mints OAuth2 access tokens on demand and injects them per call so the long-lived secret never enters the agent's prompt, memory, or logs.

Intent-based discovery

Agents search Jentic by intent (e.g., 'validate an address with experian' or 'pull a credit profile') and receive the matching Experian operation with its request schema, so the agent calls the right endpoint without parsing developer.experian.com.

Time to first call

Direct Experian integration: 3-5 days for OAuth2 setup, address vs consumer-services product separation, and FCRA-compliant logging. Through Jentic: under 1 hour — search, load, execute.

FAQs

Specific to using Experian Data Quality API API through Jentic.

Why is there no official OpenAPI spec for Experian Data Quality API?

Experian does not publish a unified OpenAPI specification covering this combination of address and consumer services. Jentic generates and maintains this spec so that AI agents and developers can call Experian Data Quality API via structured tooling. It is validated against the live API and kept up to date. Get started at https://app.jentic.com/sign-up.

What authentication does the Experian Data Quality API use?

The API uses OAuth2 with the client_credentials grant. POST /auth/oauth/v2/token exchanges your client_id and client_secret for a short-lived access token, which is then sent as Authorization: Bearer <token> on the address and credit endpoints. Through Jentic, client credentials sit in the vault and tokens are minted on demand.

Can I use POST /consumerservices/credit-profile/v2 without onboarding?

No. Consumer credit endpoints require Experian onboarding and a documented permissible purpose under FCRA in the US (or equivalent regulation in other regions). The address endpoints can typically be used by any client with credentials, but the credit profile endpoint is gated.

How do I add type-ahead address search?

Call GET /address/search/v1 with the partial input the user has typed and the target country code. The endpoint returns ranked candidate addresses, and once the user selects one you call POST /address/validate/v1 to lock the standardised result.

How do I validate an address through Jentic?

Run pip install jentic, then search 'validate an address with experian', load the POST /address/validate/v1 operation, and execute it with the address payload. Jentic obtains and refreshes the OAuth2 access token automatically using the client credentials in the vault.

What are the rate limits for the Experian Data Quality API?

Rate limits are not published in this spec. They are governed by the contract you sign with Experian and vary by product (address vs credit) and tier. Treat 429 responses with Retry-After as authoritative and back off accordingly.
