Everything you need to build on Entidex: REST API, TypeScript SDK, CLI, reconciliation, decision-survival queries, machine-readable knowledge statements, and the MCP server.
Sign up for a free API key and start reading without a paid plan. A free key can resolve any entity and read the lite Entity Profile — canonical identity, identifiers, and last-cached headline signals (AI Visibility, Sentiment, Share of Voice) — on GET /v1/entities/resolve and GET /v1/entities/{entityId}. It can also pull the complete, categorized record on GET /v1/entities/{entityId}/complete, browse the network on GET /v1/categories, and sample raw observations on GET /v1/discovery/entity/{entityId}/observations. Rate-limited and read-only.
Free quota: 1,000 monthly credits (1,500 with verified email + phone). Per-call cost: resolve = 1 credit · complete = 5 · raw observations = 2. Upgrade to Starter for unlimited lite-profile reads, or Developer API (£29/mo) for predictable flat-rate access to L1–L4.
Try it without a key:
curl -X POST https://entidex.com/api/scan \
-H 'Content-Type: application/json' \
-d '{"query":"openai.com"}' | jq .Full profile, claims, insights, drift and alerts are available on paid tiers. See pricing for what each tier unlocks.
Keyless instant value: POST a domain to /api/scan and get the claim ledger — what AI engines say vs the verified record, plus a gap score. No signup, no key.
OpenAPI spec, tier mapping, endpoint catalog and quick start. The canonical reference.
Official zero-dependency client — npm install @entidex/sdk. resolve, getEntity, complete (the full categorized record in one call), and insights, fully typed against the v1 contract.
Preview the planned UX. The CLI is in private beta — use the REST API or MCP server today.
Resolve messy entity strings (domains, names, aliases) to canonical Entidex IDs in bulk. Confidence-scored, deduped against a 1,200+ entity graph. Patterns for batch matching with thresholds, candidate disambiguation, and Wikidata cross-reference.
Resolve any creator name or profile link to the canonical creator — every cross-verified handle, with provenance and a signed record. Keyless demo on the landing page; key-gated dataset twin at /api/v1/creators/resolve.
Query the AI engines under decision pressure and measure whether your entity survives. Endpoint + interpretation guide.
Ground your agents on resolved, provenance-backed entity records over MCP and the API: resolve, verify, read, correct. One layer, any agent.
Drop Entidex into any MCP-compatible LLM client. Live entity intelligence inside your AI workflow.
Crawlable, machine-readable verified records (Markdown · schema.org ClaimReview · JSON), signed by did:web:entidex.com, discoverable via llms.txt, verifiable in-flight via the entity_verify_fact MCP tool.
