Build the AI-Powered API Your Business Systems Need
A custom API connects your disparate internal business systems with AI by creating a central data hub that standardizes information from your various tools and feeds it to models like Claude. The build complexity depends on the specific systems involved and the extent of data transformation required. For instance, integrating modern tools with clear REST APIs differs significantly from connecting legacy databases or extracting unstructured data from documents in cloud storage.
Syntora specializes in connecting disparate internal business systems with AI through custom API development. We design and build robust data orchestration layers that standardize information flow, preparing data from various sources for advanced analysis by AI models like Claude. Our approach focuses on technical architecture and clear engagement deliverables, ensuring a tailored solution for your specific integration challenges.
What Problem Does This Solve?
Many teams try to connect systems using Airtable as a central database. It works for simple data, but its API rate limit of 5 requests per second chokes when you process hundreds of documents for an AI model. Chaining tools together with an integrator often creates a different bottleneck: task-based pricing.
A 15-person marketing agency used Trello for projects, Google Drive for documents, and a custom CRM. The director wanted to ask, "Which projects are at risk of going over budget?" Answering this required manually cross-referencing Trello cards with client notes in Google Docs, a 5-hour weekly task for a project manager. The data was too siloed for any off-the-shelf dashboard.
These setups fail because they treat data integration as a series of one-way pushes. A Trello card update triggers a Slack message. A new Google Doc triggers a notification. They cannot handle a two-way conversation where an AI model needs to fetch data from three systems, analyze it, and then write insights back to a fourth. This requires a dedicated, stateful application, not a stateless workflow.
How Would Syntora Approach This?
Syntora would approach this problem by first conducting a thorough discovery phase. We'd start by auditing your existing data sources, identifying internal APIs, databases, and document repositories, and mapping the required data transformations to prepare information for AI processing. This initial phase typically involves understanding your business logic and existing data contracts, and defining clear data schemas using tools like Pydantic. We frequently use Python's httpx library for fast, asynchronous data retrieval from existing system APIs.
The core of the system would be a FastAPI application, acting as a secure central point for all data orchestration. This API would expose secure endpoints designed to abstract the complexity of your underlying systems. For example, an endpoint might accept a project identifier, then internally fetch task data from a project management tool, relevant document contents from a cloud storage API, and budget information from a CRM. This consolidated data object would then be ready for AI analysis.
We have built document processing pipelines using the Claude API for financial documents, and the same pattern applies to extracting and analyzing information from internal business documents. The consolidated data would be fed to the Claude API with a carefully engineered prompt, designed for tasks like extraction, summarization, or risk analysis. The model would return structured insights, for example, a JSON object containing a risk score and a concise summary. The FastAPI service would implement caching strategies, such as using a Supabase Postgres database, to store AI responses and avoid redundant API calls, significantly improving response times for repeated queries. The service would be deployed as a serverless function, for instance, on AWS Lambda, providing cost-effective and scalable operation.
As a key deliverable, the system would typically include a user-friendly interface, such as a dashboard built with Streamlit and hosted on Vercel, for your team to access these AI-generated insights. This interface would incorporate role-based access control, managed through Supabase, to ensure data security and relevance for different user roles. We would also implement structured logging with tools like structlog, shipping logs to a system like AWS CloudWatch with custom alarms to proactively monitor system health and detect anomalies. Typical build timelines for an integration of this complexity range from 6 to 12 weeks, depending on the number and type of systems involved. Your team would need to provide API access credentials, clear documentation of existing data structures, and define the specific business questions the AI should address.
What Are the Key Benefits?
Production System Live in 4 Weeks
From our first call to a deployed system your team is using takes 20 business days. We scope tightly to deliver a working tool quickly.
Fixed Build Cost, Minimal Hosting Fees
You pay a one-time project fee. After launch, your only cost is the direct pass-through for AWS Lambda and Claude API usage, typically under $50/month.
You Receive the Full Source Code
The entire Python codebase is delivered to your private GitHub repository. You get a production system, not a black box subscription you can't modify.
Monitoring and Alerts are Built-In
We configure AWS CloudWatch alarms that send a Slack alert if API error rates exceed 2% or latency passes 500ms. We know when things are slow.
Connects to Any Tool with an API
We integrate with modern SaaS tools like HubSpot and legacy systems like on-premise SQL databases. The API normalizes the data so the AI model doesn't care about the source.
What Does the Process Look Like?
System Mapping (Week 1)
You provide read-only API credentials for your systems. We deliver a technical diagram showing every data flow, endpoint, and transformation rule.
Core API Development (Weeks 2-3)
We build the FastAPI service and integrate it with the Claude API. You receive a secure staging URL to test the API endpoints directly.
Dashboard and Deployment (Week 4)
We build the user-facing dashboard and deploy the full system to your cloud infrastructure. You receive credentials and a walkthrough video for your team.
Post-Launch Support (Weeks 5-8)
We monitor system performance and fix any bugs that emerge. At the end of the period, we deliver a runbook with full documentation for handoff.
Frequently Asked Questions
- What does a typical project cost and how long does it take?
- Most builds are 3-6 week engagements. The primary factors determining cost are the number of systems to integrate and the cleanliness of the source data. Connecting two modern SaaS tools is straightforward. Connecting a 10-year-old custom database requires significant data mapping and transformation, which increases the scope. Book a discovery call to get a specific quote.
- What happens when an external API we rely on changes or goes down?
- We build with defensive coding practices, including retry logic with exponential backoff for API calls. If a service like Trello's API is down, our system will retry a few times before logging an error and alerting us. For breaking API changes from a vendor, our support plan covers the engineering work needed to update the integration.
- How is this different from hiring a freelance developer on Upwork?
- A freelancer can write code. Syntora delivers a production system. That includes deployment, infrastructure as code, monitoring, alerting, and documentation. The person you talk to on the discovery call is the engineer who writes the code and supports it after launch. There is no handoff to a junior developer or a separate project manager.
- Can we use a different AI model, like GPT-4?
- Yes. The core API is model-agnostic. We build an adapter layer that can call any major LLM API. We typically start with the Claude API for its large context window and strong instruction following, but we can swap in another model if you have a specific need or existing license. The choice of model can be configured via an environment variable.
- Our data is sensitive. How do you ensure security?
- Your data never leaves your own infrastructure. We deploy the entire system within your AWS account. API keys and secrets are managed through AWS Secrets Manager, not stored in code. Access to the dashboard is handled through role-based permissions, ensuring users only see the data they are authorized to view. We do not use third-party data processors.
- What kind of team is a good fit for this?
- Syntora is for 5-50 person businesses that have a clear, high-value process they want to automate with AI. You have identified a bottleneck that costs your team hours every week and cannot be solved with off-the-shelf tools. You need a hands-on engineer to build and maintain a business-critical system, not a large agency to conduct a "digital transformation".
