API Tools

Gemini 3.1 Flash-Lite runs tool calling, classification, translation, and multimodal processing via API on Google's Gemini Enterprise Agent Platform. For AI engineers building high-volume, latency-sensitive agent pipelines in production.

The all-in-one platform to design, document, manage, and observe your APIs. Built for the developers shipping them, the customers integrating them, and the agents now calling them at scale.

- Chat endpoint for selling in the chat with a sell agent - AI first Selling agent with payment processing - RazorPay, Stripe and Paypal support

Build event-driven email workflows with triggers, conditions, delays, and full run visibility.

The all-in-one platform to design, document, manage, and observe your APIs. Built for the developers shipping them, the customers integrating them, and the agents now calling them at scale.

Feed the feed, faster. Craft scroll-stopping carousels, snap them to any platform size instantly, and ride the latest trends with top tier AI models. One workspace to power your brand's social presence.

Don't let Claude and Codex roam free on your customers' SaaS data. Apideck MCP gives AI agents permissioned access to 200+ apps, including Accounting, CRM, HRIS, ATS, and more, through a single endpoint. Scoped read/write permissions and field-level redaction are enforced at the MCP layer. Works with any MCP client (Claude, Cursor, Codex, Windsurf, LangChain, Vercel AI SDK) and agent runtimes like OpenClaw and Hermes. One MCP server. 200+ apps. Production-ready.

APIEval-20 is a black-box benchmark for API testing agents. Each agent gets only a JSON schema and one sample payload, then generates a test suite. We run those tests against live reference APIs with planted bugs and score bug detection, API coverage, and efficiency. Unlike LLM-as-judge evals, scoring is fully objective: a bug is either caught or it isn’t. Tasks span auth, errors, pagination, schemas, and multi-step flows. Open on Hugging Face.

Build safer, smarter chat with CometChat Moderation, the all-in-one safety layer for conversations. From contextual AI moderation to message and media controls, plus review and escalation workflows, everything you need to enforce trust at scale. Malware & Virus Scanning is built in, scanning every file before delivery and blocking threats instantly. Turn it on from the Dashboard in minutes, no extra code required.

On Lingo.dev, teams configure localization engines: Stateful translation APIs with glossaries, brand voice rules, per-locale model chains, and AI quality scoring, and then call them via API, CLI, CI/CD, or MCP.

A reasoning model that interprets intent before it generates. Less than half the price and latency of comparable models. Two endpoints. Python, JS/TS, Go SDKs & CLI. Production grade from day one.

Realtime TTS 1.5 is #1 on Artificial Analysis, voted best in blind tests by thousands of real users. TTS-2 builds on that with six major upgrades: natural language voice direction for tone, emotion, speed, and pitch. Text-based voice design, where you describe a voice in words and generate it. Cross-lingual synthesis across 100+ languages preserving speaker identity. IPA phonetic control for brand names and rare words. And improved alphanumeric pronunciation.

Pay.sh let's agents instantly discover, access, and pay-per-request for any API autonomously. No accounts. No API keys. No subscriptions needed.

API Report Card is a free tool from SaaStr.ai that grades any B2B API for how well it works in an agent-first world. It scores APIs across categories like authentication, error handling, documentation, pagination, idempotency, and overall agent-readiness, surfaces a letter grade from F to A+, and generates ready-to-paste prompts that developers can drop into Cursor, Claude, or Replit to fix the issues.

Replyke is the complete infrastructure layer for how users interact and create content in your app. Comments, reactions, spaces, feeds, notifications, chat, follows — every system your users need, already modeled, moderation-ready, and production-ready. Stop rebuilding the same user interaction systems. Install an SDK, wrap your app in a provider, and ship your first feature in under an hour. Multi-platform: React, React Native, Expo, and Node.js.

Agent first platform where autonomous AI agents discuss news, share market signals, and debate positions. It is a social layer for agents to analyze recent events from a financial perspective.

Tabstack is a web data and automation API that delivers reliable structured output. Pass a URL and a schema, get back JSON that matches every time. Run research in one call and get cited answers back. Automate browsers without running infrastructure. The intelligence is built into every API call. No scraper to build, maintain, or watch break when a site changes. Built at Mozilla.

The fastest path to a working Voice Agent, built on the most accurate Voice AI in the market. Stream audio in, get audio back. We handle the rest. ~1s latency. Best-in-class accuracy on the stuff that matters (numbers, emails, names). Tool calling that doesn't go silent. Mid-call prompt + voice + tool updates. $4.50/hr flat. No per-token. No concurrency caps. Most devs ship a working agent the same day.

Two research agents in the Gemini API: Deep Research for low-latency interactive workflows, Deep Research Max for exhaustive async synthesis. Both support MCP data sources and native chart generation. For developers and AI engineers.

Vibe training for AI agent reliability. Describe what your agent should and should not do — Plurai generates training data, validates it, and deploys a custom model in minutes. It feels like vibe coding, but for evaluation and guardrails. No labeled data. No annotation pipeline. No prompt engineering. Under the hood, small language models deliver sub 100ms latency, 8x lower cost than GPT as judge, and over 43% fewer failures. Always on, not sampled. Built on published research (BARRED).

One API for public social data. Scrape profiles, posts, comments, videos, and transcripts from TikTok, Instagram, YouTube, X (Twitter), LinkedIn and Facebook. Pay-as-you-go credits, no rate limits, 100 free credits, no card required.
