Public API · free · Science
DOI metadata
Retrieve title, authors, journal and publication dates for a known DOI from Crossref. JSON includes source URL, retrieval time, source hash and explicit limitations. Contract and examples.
Capability catalog and prototype inventory
This inventory recovers the existing project work. Status labels distinguish the deployed API from local prototypes and proposed capabilities. Unavailable entries cannot be ordered or called on this website.
Local prototype · not deployed · Business Intelligence
Domain Intelligence
Public DNS snapshot for A, AAAA, MX, NS and TXT. The local implementation uses Cloudflare with Google Public DNS fallback on provider errors, records provenance and reports partial results. DNS records do not establish company identity, ownership or reputation.
Local demonstrator · not deployed · Developer Tools
JSON Validate
Validate JSON syntax, return formatted JSON, top-level type and object keys. A successful syntax check does not validate a domain-specific schema.
Local demonstrator · not deployed · Trust & Verification
Content Fingerprint
Compute SHA-256 and UTF-8 byte length for text. A matching hash checks byte integrity, not authenticity, authorship or truth.
Local demonstrator · not deployed · Documents
Text Intelligence
Count Unicode code points, whitespace-delimited words, lines and UTF-8 bytes. This is deterministic inspection, not semantic understanding or language-aware tokenization.
Local prototype · not deployed · Science
Bibliography audit
Process 1–20 DOIs with Crossref metadata and heuristic title comparison. Missing metadata or a mismatch is a review signal, not proof of fabrication. It does not validate scientific claims or provide complete retraction checks.
Proposed · not implemented publicly · Crypto & Blockchain
Contract Risk
A possible service for structured smart-contract risk signals on Base. Supported checks, providers and delivery quality remain to be established; no security audit or investment assessment is offered.
Proposed · not implemented publicly · Crypto & Blockchain
Wallet Intelligence
A possible structured account-activity service. Networks, coverage and interpretation remain undefined; no public wallet-analysis endpoint is available.
Proposed · not implemented publicly · Web & Research
Web Search
A possible service for finding current research sources. Provider selection, usage rights, cost and result quality require validation.
Experiment specification · not deployed · Web & Research
Page Evidence
A proposed public-page extraction contract for source URL, retrieved text, timestamp, hash, truncation and warnings. The specification excludes login, browser actions and full-site crawling. Network safety and delivery benchmarks must be completed before exposure.
Proposed · not implemented publicly · Media
Audio Transcription
A possible timestamped speech-to-text service. No audio upload endpoint, supported-language commitment or delivery price is currently offered.
Proposed · not implemented publicly · Engineering
Geometry Check
A possible geometry-file structural inspection service. File formats and validation rules are not yet defined; no engineering certification is offered.
Proposed · not implemented publicly · Geospatial
Geospatial Lookup
A possible location-to-coordinate service. Provider, licensing, coverage and precision need validation before a public offer.
Catalog scope
The original catalog spans Crypto & Blockchain, Web & Research, Business Intelligence, Documents, Science, Media, Developer Tools, Engineering, Geospatial, and Trust & Verification. These categories describe the project scope; they do not imply that every category has a working public service.
