What Are Custom Data API Services?

A Custom Data API is a structured way to make extracted and processed data available to your applications, databases, dashboards, or other business systems.

Instead of simply delivering a raw web scraping output, our approach covers the complete data flow. We collect information from the required website, app, marketplace, or other source, process and normalize the data, and then deliver it through an API or format that matches your technical requirements.

For example, a business may need product prices from several marketplaces. We can collect the required product data, standardize fields such as product name, SKU, price, currency, and availability, and then expose the processed dataset through a REST API, GraphQL API, webhook, scheduled feed, or another agreed delivery method.

The API is therefore the delivery layer, while data extraction and processing form the foundation behind it.

Key Features

Key Features of
Custom Data API Solutions

The objective is not simply to create an endpoint. We build the data pipeline behind that endpoint so the information reaching your system is structured, consistent, and aligned with your requirements.

Data Extraction from Websites, Apps & Marketplaces
The process starts with collecting the required information from the sources relevant to your business. These sources may include websites, scraping mobile applications, marketplaces, public data sources, or other permitted online platforms. The extraction approach depends on the source and the type of information required.

The collected data then moves into the processing layer before being exposed through the final delivery method.
REST & GraphQL API Integration
A REST API or GraphQL API can be used as the delivery interface for processed data, depending on how your applications consume information. The API structure can be designed around the fields, endpoints, filters, authentication requirements, and response structure your development team needs. This means your system receives the processed dataset through an interface designed for its actual use case rather than a generic API structure.
JSON Data Delivery
JSON is commonly used for application-to-application data exchange. We can structure extracted and normalized data into JSON responses based on your agreed schema. Fields, data types, nesting, naming conventions, and response structures can be defined during the project so your development team receives predictable data.
XML Feed Delivery
For systems and integrations that require XML, the processed dataset can be delivered in an XML structure aligned with the receiving system's requirements. The same extraction, processing, normalization, and validation workflow applies regardless of whether the final output is JSON, XML, or another format.
Real-Time Data API
Some use cases require data to reach downstream systems soon after a relevant change is detected. A Real-Time Data API can support these workflows where the source and collection architecture allow frequent or near-real-time updates. Depending on the use case, updates can be made available through an API, webhook, streaming mechanism, or another agreed delivery method. This is particularly relevant for use cases such as pricing, inventory, availability, and other frequently changing information.
Webhook Delivery
Webhooks can automatically notify your system when defined data events occur. For example, a webhook can be configured to send a notification when a new record is collected, a monitored field changes, or another predefined event takes place. This allows downstream workflows to respond to data changes without repeatedly polling an endpoint.
Schema Customization & Data Normalization
Different sources rarely structure information in exactly the same way. One marketplace may use one product field structure while another uses different names, formats, or units. Our Data Processing & Normalization layer standardizes these differences before the information reaches your system.

This can include: field mapping, data-type standardization, naming normalization, currency or unit normalization, duplicate handling, missing-value checks, source-specific formatting, and custom business rules. The resulting data is then delivered according to the schema agreed during project planning.

Why Choose Us

Why Choose Techdataseeders for
Custom Data API Services?

A useful API depends on the quality and consistency of the data behind it. Our approach covers the data pipeline from source collection through final delivery rather than treating API development as an isolated task.

End-to-End Data Pipeline
We manage the workflow from data extraction to processing, normalization, and delivery. This means your API or data feed is connected to an underlying data pipeline designed around the sources and information your business actually needs.
Custom Data Structure
Every business has different data models. We can map extracted fields into a custom schema based on your application's requirements, including field names, data types, nesting, and response structure.
Developer-Friendly API Design
Where an API is required, we can provide structured endpoints, authentication requirements, sample payloads, schema information, and documentation to support integration with your development team's workflow.
Ongoing Data Pipeline Support
Data sources can change over time. Ongoing projects can include monitoring and maintenance of the extraction and processing workflow so changes in source structures can be addressed and the resulting data remains aligned with the agreed schema.
Our Process

Our Process for Delivering
Custom Data API Projects

01
Source & Requirement Mapping
We start by identifying where the data needs to come from — websites, mobile apps, marketplaces, or other permitted sources — and what information your system needs. We then define the required fields, data structure, update frequency, processing rules, and final delivery method.
02
Data Extraction Architecture
Our engineers determine the appropriate method for collecting the required information from each source. The extraction architecture is selected according to the source type, data requirements, access method, collection frequency, and other project-specific considerations.
03
Data Processing & Normalization
Raw extracted information is processed before delivery. This stage can include field mapping, cleaning, deduplication, data-type conversion, normalization, validation, and application of custom business rules. The objective is to make information from different sources consistent with the schema your system expects.
04
Custom API / Data Feed Development
Once the data structure is defined, the processed information is made available through the required delivery layer. Depending on your requirements, this may include a REST API, GraphQL API, JSON response, XML feed, webhook, scheduled data feed, or another agreed integration method.
05
Integration & Data Delivery
The final data is connected to the client's system according to the agreed integration method.
