Google Patents API Is Dead — 6 Alternatives for Prior-Art and Freedom-to-Operate Search
Google Patents Public Datasets retired without a documented replacement, and the USPTO migrated PEDS into a new Open Data Portal mid-2026, breaking pipelines on the way. Here's what actually works in 2026 for prior-art, FTO, and IP-research workloads — six alternatives, side by side.
How to Build a Scientific Literature-Review Agent Without Getting Rate-Limited
Build a literature-review agent on raw arXiv + PubMed + Semantic Scholar today and you'll hit 429s before you finish ten papers. Here's why the rate limits got worse, what PaperQA / Undermind actually do under the hood, and a working pattern that survives a real review session.
Polymarket vs Kalshi API: A Developer's Side-by-Side Guide (Auth, CLOB, WebSocket, Historical Data)
Polymarket and Kalshi run the same primitive — yes/no contracts on a CLOB — through completely different APIs. One demands EIP-712 signatures and a Polygon wallet; the other is a REST endpoint with optional FIX. If you're building a forecasting agent, an arbitrage bot, or a smart-money monitor, here's the side-by-side guide that should already exist.
Citation-Grounded UK Case Law Retrieval After Ayinde v Haringey
Ayinde v Haringey changed the calculus for UK legal AI overnight. A barrister cited five fake cases generated by an LLM and got referred to the Bar Standards Board. Hallucinated citations now have professional-conduct consequences. Here's the developer's guide to building citation-grounded UK case law retrieval — TNA Find Case Law, legislation.gov.uk, neutral-citation parsing, and how to wire it into a working agent.
Wiring ClinicalTrials.gov v2 + openFDA + ChEMBL into a License-Clean Drug Intelligence Endpoint
Pharma R&D, medical-AI startups, and pharmacovigilance teams all want the same thing: one endpoint that pulls trials, labels, adverse events, and bioactivity in a license-clean way. Here's the working architecture, with the trap doors that have surprised teams in production.
Build a Research Agent with Search + URL Extract (Claude tool use, end-to-end)
Most 'AI research agent' tutorials stop at 'here's a tool definition.' This one ships a working agent: question in, cited answer out. Search, extract, reason, cite — all under 120 lines of Python.
Building a Due-Diligence Agent on SEC Filings (10-K, 10-Q, 8-K, Earnings)
Reading a 10-K is mostly Ctrl+F. Doing it for fifty companies is a job. Replace the boring 80% with a search-and-extract agent against SEC EDGAR — keep the 20% that matters for the human analyst.
Why APIs Should Charge Only on Success — The Case for HTTP-200 Billing
Most APIs charge on every billable call. AI agents retry on flaky upstream services constantly — which means the legacy 'always charge' model effectively taxes resilience. Here's the case for billing only on HTTP 200, and what it changes about how you design agents.
Tavily vs Exa vs Serper vs API Pick : quelle API de Web Search choisir pour vos LLM ?
Tavily, Exa, Serper et API Pick promettent tous d'être la couche de recherche de votre LLM. Ils diffèrent fortement sur le format, les filtres et la facturation. Comparatif terrain.
Firecrawl vs Jina Reader vs API Pick : APIs d'extraction d'URL comparées
Si vous avez déjà déployé un agent qui lit une liste d'URL et résume, vous connaissez la 'taxe de nettoyage des URL'. Firecrawl, Jina Reader et API Pick Extract la résolvent différemment. Comparatif terrain.
Ajouter une Web Search temps réel à un agent OpenAI ou Claude en 4 étapes
Vous voulez que votre agent étaye ses réponses avec de l'info à jour ? Il vous faut exactement deux choses : une API de recherche qui rend des snippets prêts pour LLM, et une définition d'outil que le modèle peut appeler. Ce guide fait les deux en 4 étapes.
Construire un agent de briefing matinal avec la News Search API
Fondateurs, PM et analystes veulent la même chose à 8h : un digest propre de ce qui a changé pendant la nuit. Avec une News Search API, un LLM et une plateforme de cron, vous le construisez en un après-midi.
