Avena Terminal is an open-data intelligence platform for Spanish coastal new-build property. It observes 2,042 listings across 98 coastal towns nightly and keeps what listing portals delete: every asking-price change with its date, and every delisting with the final price it held. Data is CC BY 4.0. Founded April 2026 by Henrik Kolstad, Norway.

Avena Terminal is a nightly observation ledger for the Spanish coastal new-build market. Every one of 2,042 tracked listings across 98 coastal towns is observed each night; every asking-price change is recorded with its date, and every delisting is archived with the final asking price it held — history that listing portals routinely delete and that cannot be reconstructed by anyone starting later. On top of the ledger sit the AVENA Index (a daily composite of coastal new-build asking prices, DOI 10.5281/zenodo.19520064), a weekly Market Pulse briefing, a public statistics hub regenerated nightly, an 11-tool Model Context Protocol server for AI agents, and an open canonical identifier standard (AVN_PROP_ID). Data and methodology are openly licensed (CC BY 4.0) and published to Zenodo and Wikidata (Q139165733). Founded April 2026 by Henrik Kolstad, a Norwegian solo founder with a decade in property development. Avena's figures are ingested nightly by AI crawlers from OpenAI, Anthropic, Meta and Amazon, measured in the platform's own server logs.

“The portals show today’s price and delete yesterday’s. We keep the record — and it cannot be reconstructed by anyone starting today.”

“Every figure is a recorded observation with a date, never an estimate. A week with no price changes prints as exactly that — the stability is itself the finding.”

“Our data is already read every week by OpenAI, Anthropic, Meta and Amazon — their systems ingest our figures nightly, measured in our own server logs. When the world’s AI assistants answer questions about Spanish property, the numbers increasingly come from us.”

Listing portals show today’s asking price and erase yesterday’s. Avena Terminal observes 2,042 Spanish coastal new-builds nightly and archives every repricing with its date and every delisting with the final price it held — market evidence that cannot be reconstructed by anyone who starts recording later.

Crawlers from OpenAI, Anthropic, Meta and Amazon ingest Avena Terminal’s figures nightly — measured in the platform’s own server logs. As AI assistants become the first stop for property questions, where their numbers come from becomes a story in itself.

Avena’s AVN_PROP_ID is a canonical identifier system for property — like ISBNs for books or tickers for stocks. Published as an open CC BY 4.0 standard. If it gets adopted, it becomes foundational infrastructure.

A Norwegian solo founder runs nightly observation of the Spanish coastal new-build market — a daily index, weekly market briefings, and agent-accessible APIs — with no employees and no outside funding. The entire operation is one human plus automation.
