Identity Resolver

Resolve public social profiles into one stable JSON identity.

Identity Resolver turns public Facebook, Instagram, and LinkedIn profile references into a predictable JSON object for applications that need reliable social identity cards. Send a platform plus username, numeric Facebook profile id, or public profile URL, and the service returns platform, id, name, username, avatar, picture, cover, verified status, and profile URL when public metadata is available. Successful responses always include name and picture; otherwise the API returns a precise structured error instead of partial data.

Resolve public social identities into a stable JSON profile

Identity Resolver is a lightweight API for products that need to normalize public social profile references before storing, displaying, or enriching them. Instead of keeping a raw Facebook, Instagram, or LinkedIn handle, your application can request a consistent identity object with platform, id, username, name, picture, avatar, cover, and verified status.

The service is intentionally free and simple. It is useful for lead tools, CRM enrichment, social proof widgets, profile import flows, creator databases, and admin panels where a user may paste either a username, profile id, or public profile URL.

Required name + picture

Successful responses always include a non-empty name and picture so your UI never receives a half-empty identity card.

Facebook username or id

Facebook accepts both usernames and numeric profile IDs, including public personal profiles when public metadata is available.

Stable JSON shape

The response keeps the same keys across Facebook, Instagram, and LinkedIn for predictable parsing.

Completely free

No token, no checkout, and no subscription plan is required for basic identity resolution calls.

How it works

How developers use the service

01

Send platform and identifier

Call /api/identity-resolver/v1/resolve with platform plus username, id, identifier, profile, or url.

02

Resolver builds public profile candidates

For Facebook, usernames and numeric profile IDs are converted into the correct public profile URL patterns.

03

Public metadata is inspected

The service reads public metadata such as Open Graph and title tags, then normalizes the result.

04

Use the stable identity object

Store name, picture, avatar, username, platform, verified state, and profile URL in your product.

Use cases

Where Identity Resolver helps

  • Lead enrichment tools that store social profile references.
  • CRM forms where users paste Facebook, Instagram, or LinkedIn handles.
  • Social proof widgets that need a name and profile picture before rendering.
  • Creator, candidate, partner, or customer directories.
  • Admin panels that need to validate whether a pasted social identity can be displayed.

Resolver Capabilities

Facebook, Instagram, and LinkedIn profile metadata normalized into one response format.

Facebook identity resolution

Accepts Facebook usernames, profile URLs, and numeric profile IDs, including public personal profiles when metadata is available.

Instagram and LinkedIn

Normalizes public Instagram and LinkedIn profile metadata into the same response shape.

Required name and picture

A successful response always includes both name and picture, so user-facing cards are not rendered with missing core identity data.
