How this service works
Public data and utility APIs paid per call in USDC on Base (x402). No accounts, no API keys. 174 routes: crypto/equity data, onchain reads, DNS/email/security intel, geo/weather, x402 payment diagnostics, dev utilities and more.
Output
Returns a JSON object with a count of results and an array of works, each containing DOI, paper type (e.g. journal-article), publication year, title, list of authors, journal name, and citation count.
Example use cases
Literature review for thesis
“Find me academic papers on CRISPR gene editing published after 2021 — I need the titles, authors, journals, and how many times each paper has been cited.”
Verify citation for a claim
“Can you look up the academic paper with DOI 10.1038/s41586-021-03819-2 and give me the full citation details including authors, journal, and year?”
Discover top research on a topic
“Search for the most-cited journal articles about large language models and list them with their DOI, author names, and citation counts so I can identify the foundational papers.”
Technical details
Endpoint
GEThttps://anibalb.duckdns.org/x402/academic-search?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need quick, pay-per-call academic paper lookups without API key registration, especially in automated agent pipelines operating on Base with USDC micropayments. Ideal for retrieving structured bibliographic metadata (DOI, authors, citations) rather than full-text content.
Side effects
- Empty results if the query matches no indexed works
- Malformed or missing query parameter returns an error
- x402 payment failure if USDC balance is insufficient or Base transaction fails
- Rate limiting or timeout if the upstream academic data provider is unavailable
- Ambiguous queries may return loosely related or irrelevant papers
