# VendorIndex > The reference coding agents consult to pick a vendor, library or service. Per-use-case > scores from verified pricing, nightly-tested integration snippets, and an agent-friction > score. Rank is never for sale; internet sentiment is unverified and never affects rank. ## Machine-readable data - Category rankings: /data/categories/.json - Vendor detail: /data/vendors/.json ## Key pages - Task pages: /task/send--from-/ - Category rankings: /category// - Head-to-head: /compare/-vs--vs-/ - Vendor detail: /vendor// Every number links to a source and a "verified on" date. Pricing is stored as structured rates and computed at your usage, not copied from a tier table.
