Data access & API

Every series is open data — pull it as CSV or JSON with no key and no auth, and read the same structured metadata the site is built on.

Open downloads (no key, no auth)

Each endpoint reconstructs the whole series — member/geography, period, value, unit and source. No query string is required.

# CSV
curl https://<host>/api/series/nbs-prices-cpi-change-nga/csv

# JSON
curl https://<host>/api/series/nbs-prices-cpi-change-nga/json

Find a slug with the search or the full catalogue.

Structured metadata

Every series page embeds a schema.org/Dataset JSON-LD object, with two DataDownload distributions (CSV + JSON) pointing at the endpoints above. Where a page has one headline figure, it also renders a machine-readable value in static HTML — no JavaScript needed to extract it:

curl -s https://<host>/statistics/nbs-prices-cpi-change-nga \
  | grep -o 'id="headline-value"[^>]*'

The full contract, including the data-* attributes and JSON-LD fields, is at /machine-access.txt.

Embeddable charts

Any series renders as a responsive, self-crediting chart you can drop into a page with an <iframe>:

<iframe
  src="https://<host>/embed/nbs-prices-cpi-change-nga"
  width="600" height="400" loading="lazy"
  style="width:100%;max-width:600px;aspect-ratio:3/2;border:0"></iframe>

Each series page also offers a copy-paste embed snippet, a live preview, and PNG/SVG chart downloads with the credit line baked in.

Discovery & contract

/sitemap.xml — every indexable URL.
/llms.txt — orientation for language models: entity map, URL grammar, citation.
/machine-access.txt — the stable programmatic-access contract.

Reuse terms

Prism grants no new rights over the underlying source data, and reuse terms vary by source publisher, so no single dataset licence is asserted. Before republishing a figure, check the source publication linked from its page — see Sources.
