Changelog

What changed, in public. The catalogue, the verification rules and every agent surface.

2026-11-12

Public site refresh

The marketplace, listing pages, bundles, provider pages, guides, docs and receipts are now available on the public site. The catalogue keeps the same x402 prices and direct USDC settlement on Base.

2026-11-12

Spotify API v2

Added 23 Spotify v2 routes: catalogue search, track, album and artist metadata, complete artist discographies, artist playlists, related artists, discovered-on and featuring playlists, similar albums, podcasts, episodes, audiobooks, chapters, genres and public user profiles. Every v2 route is $0.03 per call on Base and accepts a Spotify URL, URI or id without a Spotify login or API key.

2026-11-12

Spotify Artist Research bundle

Added a five-step bundle for music research: search for an artist, resolve the profile, read the complete discography, find related artists and collect artist playlists. Each step is a normal paid call, so an agent can stop or branch at any point.

2026-11-11

Spotify track metadata

Added the Spotify track endpoint with title, artists, release date, duration, explicit flag, playable state, preview URL and artwork. The track route is $0.02 per call on Base. Playlist, album and artist routes also accept ?id= and an id field in JSON bodies.

2026-11-11

Spotify artist metadata

Added the Spotify artist endpoint with an artist image, monthly listeners, followers and top tracks. Each top track includes collaborators, duration, explicit flag, playable state, preview URL and artwork. The artist route is $0.02 per call on Base.

2026-11-10

Spotify album metadata

Added the Spotify album endpoint with album artists, type, release date, cover art, track count, duration, explicit count, copyright lines and the full ordered track list. The album route is $0.02 per call on Base.

2026-11-10

Spotify API for agents

Added the Spotify API for agents with playlist intelligence: ordered tracks, artists, durations, explicit flags, preview links and optional album enrichment. The playlist route is $0.02 per call on Base.

2026-11-10

Email verification improvements

Added stronger syntax rules, internationalised domain support, null MX and implicit MX detection, disposable and role-account flags, typo suggestions, a confidence score and a checks array. The route still does not send mail or claim that a mailbox exists.

2026-11-10

Agent metadata on every listing

Added a For AI agents summary, explicit scope and intent phrases to every first-party listing. The fields appear on the listing page, in the JSON and Markdown records, in MCP discovery and in agent search.

2026-11-10

API bundles and endpoint validation

Added outcome-oriented API bundles and a free x402 endpoint validator. Each bundle lists its steps, estimated cost, prompt and sample output so an agent can follow a complete workflow instead of guessing the order.

2026-11-10

Blog and guides

Added a blog with original articles on agent discovery, x402 pricing, verification and MCP versus OpenAPI. Every article has a Markdown twin, BlogPosting structured data and an RSS feed.

2026-11-09

Agent-ready guides

Published x402 in 60 seconds, best APIs for agent traffic, MCP server best practices and the agent-ready API checklist.
