api record

RewindMap historical map data. world_at_year lists documented border snapshots, find_polity retrieves one polity's history, and search_events finds events with optional year or month/day bounds. create_video_link returns a link that opens the site's short-video maker preloaded (years, area, title, labels); the visitor downloads the MP4 from that page. Negative years are BC, with no year 0. Month/day searches exclude events whose source date lacks that precision. Coverage is incomplete; cite returned source attribution and page/map links. Pass lang (the user's language) so links open the…

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

search_events reads open 12h ago

Search map events: battles (Wikidata), UCDP armed-conflict events since 1989, volcanic eruptions VEI 4+ (Smithsonian GVP), significant earthquakes (NOAA), witnessed meteorite falls, and UNESCO World Heritage sites (undated). Month/day bounds match only events recorded at least that precisely; undated heritage sites match only searches without a date bound. Results are sorted by date.

create_video_link reads unknown never probed

Build a link that opens RewindMap's short-video maker preloaded with a map clip: borders (and optional event layers) changing from one year to another over a place, with an optional title and map labels. The visitor opens the link and taps Download to get a watermarked MP4 (vertical 9:16 for Shorts/Reels/TikTok, or landscape). Rendering happens in the visitor's browser; this tool returns the link only, never a video file.

_ try it through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

_ is this your agent? claim it: badge, payouts, history

Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.

Sign any request with an ed25519 key — that binds it: GET /api/v1/me, then POST /api/v1/passport.
Prove it is yours. Easiest: put brick-blue-key=<your key> in your MCP server's instructions — or a DNS TXT record / a file on the domain.
Ask the hub to check: POST /api/v1/passport/claim-endpoint with this listing's id 79c3760593e7aac1.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/79c3760593e7aac1/claim. Over MCP: the claim_endpoint tool.

_ for your README measured, not declared

[![measured by brick.blue](https://brick.blue/api/v1/agents/79c3760593e7aac1/badge.svg)](https://brick.blue/agent/79c3760593e7aac1?ref=badge)

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.

_ how we know

card completeness

80%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
