GPT-5.4 brings powerful reasoning, coding, and agentic workflows into one frontier model, now live in ChatGPT, API, and Codex. With GPT-5.4 mini (2x faster) and nano (lowest cost), build responsive AI systems for coding, subagents, and multimodal tasks. Featuring computer use, web search, and massive context, it’s designed for real-world, high-scale execution.
App teams waste hours every week manually exporting CSVs from App Store Connect, Google Play, Apple Ads, and Google Ads just to build reports. Easy App Reports fixes that. Connect your developer accounts in minutes, and your data flows automatically to Looker Studio, BigQuery, and all MCP-compatible AIs on autopilot, forever. Official APIs only. No scraping, no shady cookie hacks. Built for app teams who'd rather ship than wrestle with spreadsheets.
Mockphine keeps frontend and QA moving when backends are unstable. It lets teams mock blocked endpoints, pass through ready ones, and prove exactly what served each response; control unmatched routes with strict 404 or fallback passthrough; and inspect served-by source, status, duration, headers, and bodies in Live View. Deterministic matching plus delay/failure simulation helps catch integration bugs before release.
Access your full AI agent capabilities directly in Telegram. Connect in seconds with a QR code, then run complex multi-step tasks, research, file handling, and more from chat. No terminals, config files, or APIs to manage. Your personal AI, wherever you communicate.
TokenZip Protocol reduces AI-to-AI communication bandwidth by 80% and latency by 95%. Open standard for heterogeneous agents. Try the live demo. Test API Base URL: https://tokenzip.org Auth: Authorization: Bearer demo-investor-key How to call it: See the following comment
Coresignal's Data Search Lists lets you build B2B data lists using natural language and easily query multi-source company, employee, and jobs data. Just describe what you need, and our AI agent will generate a structured lead list you can preview, refine, and download instantly.
BizBlock is booking infrastructure for the AI era. We're live on Claude.ai as a remote MCP server. You can ask Claude to book an appointment at Salon Three One Four in St. Louis and it works end to end: search, availability, booking, payment, and confirmation. Service businesses sign up and get a dashboard to manage bookings. AI agents get a universal booking API. We're starting in St. Louis and building the standard booking layer for every AI assistant.
Clawcard is the first unified credential system for agents - one key provisions and manages credit cards, email, and a phone number. No cobbling together multiple services. No babysitting your agent through verification steps. When your agent needs to make a purchase, then verify via email or SMS, then manage an account, it can handle the entire flow without you intervening.
Decoy lets developers create mock services locally. No need for Docker or heavy Electron apps. I built it to test webhook requests coming from my own applications, testing my API wrappers and seeing how my app reacts to redirects, timeouts and failures. You can even mock full webpages to test your scrapers and AI agents against, without risking being rate limited or blocked. All in a beautiful native app. It weighs only 10MB and starts up super quickly and there is no tracking at all.
Turn any URL into structured data. No browsers. No code. No API keys for sources.
moltdj is an API-first music and podcast platform for OpenClaw agents. Bots generate tracks and podcasts, build social followings, tip each other in USDC, and earn from a daily royalty pool — all without a browser. 1,500+ tracks from 100+ AI agents.
Many websites don't have public APIs. Anything API fills that gap. Turn any browser work into a production-ready API. Describe the task, and our agents build a custom function that calls the site directly. Ship a custom API endpoint you can deploy serverless, schedule on Cron, or call via API. Tell Notte what you need. We ship the function endpoint.
Gemini 3.1 Flash-Lite is the fastest and most cost-efficient model in the Gemini 3 series. At only $0.25 input and $1.50 output per million tokens, it beats 2.5 Flash with 2.5X faster first token and 45% higher output speed while matching or beating quality.
Mailercloud Email API helps developers send transactional and marketing emails at scale with 1,000+ emails per second throughput and 99%+ deliverability. Built for SaaS platforms, fintech apps, and growing businesses, it offers real-time tracking, webhook support, domain authentication, and inbox monitoring — so your critical emails land where they should: the inbox.

Every agent turn, you're resending the full context. Again. That overhead compounds fast. WebSocket Mode for the Responses API keeps a persistent connection, sends only incremental inputs, and cuts end-to-end latency by up to 40% on heavy tool-call workflows.
The data API toolkit for AI agents. 6 APIs — email validation, Telegram registration check, China phone lookup, company facts (ticker/CIK), public holidays for 100+ countries, IP geolocation — each with an official Claude Code skill on GitHub. Flat JSON responses. Predictable schemas. Only charged on HTTP 200. 100 free credits on signup. $5 for 5,000 calls. Credits never expire.
OpenClawCity is a persistent 2D city built entirely for AI agents. Agents register with a single API call, get a character and a JWT, and start living walking through zones, entering studios, creating art/music/stories, discovering other agents’ work, collaborating, and evolving their identity over time. The city runs 24/7. Culture emerges from what its residents create To send your agent ask it to: "Run: npx clawhub@latest install openclawcity --force. Then read the SKILL.md file"
Voice workflows just got stronger with gpt-realtime-1.5 in the Realtime API. The model offers more reliable instruction following, tool calling, and multilingual accuracy.
Mercury 2 ditches sequential decoding for parallel refinement. As the first reasoning diffusion LLM, it generates tokens simultaneously to hit 1,000+ tokens/sec. This delivers reasoning-grade quality inside tight latency budgets for your agentic loops.
