Last month I needed to add AI features to two side projects.
One required resume parsing (80+ languages). Another needed SEO meta tags and product descriptions.
I didn't want to spend weeks fine‑tuning models or fighting with Python environments.
So I did what any lazy developer would do: I tested ready‑made AI APIs.
I tried over a dozen. Some were terrible. A few were surprisingly good.
Below are the 10 I'd actually use again.
Plus – because I know many of you build side projects – I've included which ones offer solid referral programs (yes, passive income).
What you'll get from this post
✅ The API that saved me 12 hours of parsing resumes
✅ Which platforms offer 30% lifetime recurring commissions
✅ A comparison of pricing models (free tiers, pay‑as‑you‑go, subscriptions)
✅ One tool I'll never touch again (spoiler: none here – I only kept the good ones)
Let's go.
1. SharpAPI – The AI Workflow Toolkit That Actually Saves Your Weekends
I'll be honest: SharpAPI surprised me.
It's not just another generic LLM wrapper. It gives you 30+ pre‑built endpoints for boring but necessary tasks.
What I actually used it for:
Parsing resumes from PDF, DOCX, and even images (80+ languages). Worked flawlessly.
Generating SEO meta titles and descriptions for an e‑commerce prototype.
Translating product descriptions into 15 languages in one batch.
The killer feature (I didn't expect to love it):
Custom Workflows – a visual no‑code builder.
You write a prompt in plain English, for example:
"Extract the product name, price, and availability from this HTML"
SharpAPI instantly turns that into a live REST endpoint. No backend code. No waiting for your ML engineer.
It feels like cheating.
Pricing:
Free trial: 100,000 words – no credit card required.
Paid plans start at $20/month (credit‑based, pay‑as‑you‑go also available).
Pros (from my experience):
Integrates in an afternoon – SDKs for Python, Node, PHP, Laravel, .NET, Flutter.
SOC 2 Type II certified – enterprise‑grade security. Important if you handle customer data.
Referral program: 30% lifetime recurring commission. Bring a client once, get paid every month forever. Minimum payout $50.
Cons:
Outages (rare) can break your app – that's the risk of any external API.
For massive scale (millions of calls/month), rolling your own open‑source model might be cheaper.
Best for: MVPs, SaaS products, and developers who hate reinventing the wheel.
2. Together AI – Open‑Source LLMs Without the GPU Headache
Together AI gives you API access to 200+ open‑source models – Llama 4, Qwen 3, Mistral, etc.
Pricing:
0.27–3.00 per million tokens. New users get $5 free credits.
Pros:
Huge model choice.
Fast inference – one of the fastest I've tested.
Much cheaper than AWS SageMaker.
Cons:
No individual referral program.
Pricing can be confusing (different models = different costs).
Best for: Teams that need flexibility and no vendor lock‑in.
3. Deepgram – Speech‑to‑Text That Actually Works in Real Time
Deepgram does one thing well: transcribing audio with low latency. Their Nova‑3 model handles accents and background noise impressively.
Pricing:
$0.0166 per 10 minutes of audio.
Voice Agent API: $4.50/hour.
Free tier: 500+ hours/month for developers.
Pros:
Sub‑700ms latency – fast enough for live captions.
Works with messy Zoom recordings.
Clear docs and SDKs (Python, Node, Go).
Cons:
No native referral program (they use FlexOffers network).
Voice agent features are still evolving.
Best for: Voice assistants, meeting transcriptions, podcast apps.
4. Replicate – Run Thousands of Open‑Source Models with One API
Replicate is a catalog of 1000+ open‑source models – image generation, video, audio, LLMs.
Pricing:
Pay‑per‑second of compute. SDXL costs ~$0.003 per image.
$25 free credits for new users.
Pros:
Insane variety. Remove backgrounds, generate music, etc.
Simple API – just POST to one endpoint.
New models appear weekly.
Cons:
No referral program.
Costs can spiral – always check model pricing before scaling.
Best for: Prototyping, creative coding, exploring what's possible.
5. Apify – Web Scraping Turned into a Platform
Apify is a web scraping and automation platform (not pure AI). You run scrapers (Actors) in the cloud; many use AI to parse data.
Pricing:
Free plan with $5 monthly credits.
Paid tiers from 5 to 499/month.
Pros:
Huge library of pre‑built Actors (Amazon scraper, Google Maps extractor, etc.).
Write your own Actors in Node.js or Python.
*Referral program: *~$2 per active user (one‑time).
Cons:
AI isn't built‑in – you need to combine Actors or add your own.
Pricing gets complex with multiple Actors.
Best for: Data extraction, competitor monitoring, custom scrapers.
6. n8n – Self‑Hosted Workflow Automation
n8n is the open‑source alternative to Zapier. Build multi‑step automations visually, and host everything yourself.
Pricing:
Free Community Edition (self‑hosted) – unlimited.
Cloud plans start at €20/month.
Pros:
Total data control (self‑hosting = privacy win).
400+ nodes to connect with (APIs, databases, email, etc.).
Write custom JavaScript/Python code inside workflows.
Referral program: 30% recurring commission for 12 months on Starter/Pro plans.
Cons:
Self‑hosting requires maintenance (Docker, backups, updates).
Visual builder has a learning curve.
Best for: Developers who want full control and don't trust cloud automation.
7. Relevance AI – Build AI Agents Without Code
Relevance AI lets you build, deploy, and manage AI agents – customer support bots, sales agents, research assistants – via a no‑code interface.
Pricing:
Free "Build" plan.
Pro plan from $19/month.
Pros:
No‑code agent builder is surprisingly flexible.
Chain multiple agents together (multi‑agent systems).

Cons:
Lock‑in: migrating complex agents away is hard.
Pricing jumps quickly with high usage.
Best for: Startups that need AI staff without ML engineers.
8. Pipedream – Code‑First Integration Platform
Pipedream is my favorite for gluing APIs together. Write small code steps (Node.js or Python) that run on HTTP requests, timers, webhooks, etc.
Pricing:
Free plan: 10,000 invocations/month.
Paid plans from $29/month.
Pros:
Built‑in secret management, delays, error handling.
Supports 2,000+ pre‑built app integrations.
Referral program: 33% recurring commission (waitlist currently).
Cons:
Not purely AI – it's a platform for workflows that use AI APIs.
Free plan has tight limits.
Best for: Developers who orchestrate multiple APIs without spinning up servers.
9. Eden AI – Unified API Gateway for 500+ Models
Eden AI gives you one API key to call models from OpenAI, Anthropic, Google, and 500+ others.
Pricing:
Pay‑as‑you‑go. You pay provider's price plus 5.5% platform fee. No hidden markup.
Pros:
Easy fallback: if one model fails, Eden retries with another.
Compare performance and cost across providers.
Clean, unified response format.
Cons:
No referral program (custom deals only).
Extra hop = slightly higher latency.
Best for: Production apps that need reliability and provider flexibility.
10. Twelve Labs – Video Understanding That Actually Works
Twelve Labs builds AI that understands video – not just captions, but scenes, actions, objects, and speech. Their Pegasus‑1 model is genuinely impressive.
Pricing:
Free plan: 600 minutes of video.
Search API: from $4 per 1,000 queries.
Pros:
Semantic video search ("find the scene where the cat jumps") works shockingly well.
Good documentation and SDKs.

❓ FAQ – What I actually get asked
1. Which has the most generous free tier?
Deepgram (500+ hours transcription free). Replicate ($25 credits). SharpAPI (100k words, no credit card). For volume, Deepgram wins. For flexibility, Replicate.
2. Can I use multiple AI APIs together?
Yes – that's the smart move. Deepgram for speech, SharpAPI for documents, Together AI for LLM. Pipedream or n8n help glue them together.
3. Easiest for a junior developer?
SharpAPI and Deepgram have the cleanest docs and ready‑to‑run snippets. Replicate is also simple (just POST). Avoid Twelve Labs and Eden AI as first projects – powerful but steeper.
4. Hidden costs to watch out for?
Together AI and Replicate: costs depend on model size – set billing alerts. Eden AI: +5.5% fee. SharpAPI and Apify have predictable monthly caps – safer for production.
5. Which referral program actually pays out?
SharpAPI (30% lifetime) and n8n (30% for 12 months) are transparent. Relevance AI pays but has a $100 minimum. Avoid "up to X%" without a fixed number – usually low effective rates.
6. Is SharpAPI really SOC 2 Type II certified? Why does that matter?
Yes. Independent auditor verified their security, availability, and confidentiality. If you're building for enterprise or handling sensitive data, this removes compliance headaches. Not many AI APIs at this price point have it.
7. What exactly is a "Custom Workflow" in SharpAPI?
A no‑code visual builder. You write a prompt in English – e.g., "extract name, price, and availability from this HTML" – and SharpAPI turns that into a dedicated API endpoint. No backend code. Insane for rapid prototyping.
8. Can I self‑host any of these?
Only n8n (Community Edition) is fully self‑hostable. The others are cloud‑only. If data privacy is your top priority, go n8n or run open‑source models yourself (more work).
Final take – my honest recommendation
Need resume parsing, SEO generation, or custom AI workflows without coding? → SharpAPI (also best referral program for passive income).
Building a voice assistant? → Deepgram.
Want to play with hundreds of open‑source models? → Replicate or Together AI.
Automating tasks across multiple services? → n8n or Pipedream.
Don't want to manage infrastructure? → Apify or Relevance AI.
If you want to earn passive income while recommending tools you actually use – SharpAPI (30% lifetime) and n8n (30% for 12 months) are your best bets right now.
Have you used any of these in production? Let me know in the comments – I'd love to hear your war stories.
