API-плейбук для разработчиков и AI-агентов
Туториалы, сравнения и кейсы — чтобы подкреплять ответы LLM источниками, собирать пайплайны агентов и выводить AI-фичи в продакшен.
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: какую Web-Search API выбрать для LLM?
Tavily, Exa, Serper и API Pick — все обещают быть слоем поиска для вашего LLM. Они заметно отличаются по формату, фильтрам и тарификации. Прямое сравнение от инженера, который шипит агенты.
Firecrawl vs Jina Reader vs API Pick: сравнение API для извлечения контента из URL
Если вы хоть раз шипили агента, читающего список URL и делающего саммари, налог на чистку URL вам знаком. Firecrawl, Jina Reader и API Pick Extract решают это по-разному. Практический вывод.
Как добавить веб-поиск в реальном времени в OpenAI- или Claude-агента за 4 шага
Хотите, чтобы агент опирался на свежую информацию? Нужны ровно две вещи: search API, возвращающий LLM-friendly snippets, и описание инструмента, которое модель сможет вызвать. Этот гайд делает обе за 4 шага.
Утренний brief-агент на News Search API
Основатели, PM и аналитики хотят одного и того же в 8 утра: чистый дайджест того, что изменилось за ночь. С News Search API, LLM и cron-платформой это собирается за полдня.
