Compare two facial images using Didit Face Match API to verify identity by returning a similarity score with optional rotation and multi-face detection.
Compare two facial images using Didit Face Match API to verify identity by returning a similarity score with optional rotation and multi-face detection.
Hand the extracted package to your coding agent with a concrete install brief instead of figuring it out manually.
I downloaded a skill package from Yavira. Read SKILL.md from the extracted folder and install it by following the included instructions. Tell me what you changed and call out any manual steps you could not complete.
I downloaded an updated skill package from Yavira. Read SKILL.md from the extracted folder, compare it with my current installation, and upgrade it while preserving any custom configuration unless the package docs explicitly say otherwise. Summarize what changed and any follow-up checks I should run.
Compares two facial images to determine if they belong to the same person. Returns a similarity score (0-100). Key constraints: Supported formats: JPEG, PNG, WebP, TIFF Maximum file size: 5MB per image If multiple faces in an image, the largest face is used for comparison Both user_image and ref_image are required Capabilities: Similarity scoring, age estimation, gender detection, face bounding boxes, configurable decline threshold, optional image rotation for non-upright faces.

All requests require x-api-key header. Get your key from Didit Business Console → API & Webhooks, or via programmatic registration (see below).
If you don't have a Didit API key, create one in 2 API calls: Register: POST https://apx.didit.me/auth/v2/programmatic/register/ with {"email": "you@gmail.com", "password": "MyStr0ng!Pass"} Check email for a 6-character OTP code Verify: POST https://apx.didit.me/auth/v2/programmatic/verify-email/ with {"email": "you@gmail.com", "code": "A3K9F2"} → response includes api_key To add credits: GET /v3/billing/balance/ to check, POST /v3/billing/top-up/ with {"amount_in_dollars": 50} for a Stripe checkout link. See the didit-verification-management skill for full platform management (workflows, sessions, users, billing).
