For developers and AI agents

Everything we know, open through the API

Every grant with its solicitation documents and extracted requirements, every funding organization, every investor with dossier and funding events, every longevity company with scores, per-dimension rationale, theories and evidence, heroes, rated projects, scientific theories and the canonical ideas graph. No key needed. Data we produced is CC BY 4.0.

Four ways in

REST API at https://eternalsearch.net/api/v1: documentation, OpenAPI 3.1 spec (works as a ChatGPT Action or any OpenAPI client). Every list is paginated (limit up to 200, offset, pagination.has_more).
MCP server at https://eternalsearch.net/api/mcp: add it as a connector in Claude, ChatGPT or Cursor; in Claude Code run claude mcp add --transport http eternal-search https://eternalsearch.net/api/mcp. Tools for every family plus resources for the catalogue and the spec.
Nightly dumps at /datasets/index.json: one NDJSON.gz file per family with size and SHA-256, for bulk reads without paging.
Change feed at /api/v1/changes: rows updated since a moment, with a cursor, so a mirror stays current cheaply.

AI agents: read /llms.txt first, or /llms-full.txt for the endpoint list and worked examples.

Licence and text policy

Data produced by Eternal Search (scores, rationale, extracted requirements, theories, summaries, the ideas graph) is licensed under CC BY 4.0. Attribution: “Eternal Search (eternalsearch.net), powered by Open Longevity”. Every API response and every dump carries this licence line.

Third-party texts we harvested (articles, posts, transcripts, documents) keep their authors’ rights. Each record carries text_policy: full returns the whole text for public-domain, open-licence, press-wire or funder-hosted sources; excerpt_only returns a short quotation plus the source URL, and you fetch the original yourself. Our own summaries, quotes used as evidence and structured extractions are always open.

What stays behind a key

Nothing analytical. A team key adds the team’s own working data (CRM, meetings, contacts, research jobs, pipeline state) and full third-party text for analysis. The personal layer of investor research (health, family, photo observations, aircraft, money observations) is served only to the Open Longevity team and is never part of the open API, the MCP server or the dumps. No open endpoint runs a model or spends tokens; everything you read already exists in the database.

Profiles of people are professional and analytical. Anyone we profile can ask for correction or removal through the privacy page; removals propagate to the API, the dumps and the change feed.

Limits

Anonymous requests: 600 per minute per IP, answered with 429 and Retry-After beyond that. Use the dumps for bulk reads. CORS is open for browser clients.
