Automation of bid increases through Hotline API (Auctions)

Budget: 12000 UAH Deadline: 7 days

Hello.

I am implementing a service for automatic bid management through the Hotline Auctions API with a secure architecture and risk control.

Here’s how I propose to do it:
• Python service with modular logic (core + API client + rule engine).
• Configuration via YAML/JSON (min_bid, max_bid, step, budgets, working hours, change limits).
• Scheduler (cron/apscheduler) with customizable frequency.
• Protection against "bid ramping": limit on changes per hour and daily cap on growth.
• Complete logging in the database (PostgreSQL) + CSV export.
• Telegram notifications for errors, hitting max_bid, exceeding budget.
• Retries with backoff + safe stop during API instability.
• Docker for deployment on any VPS.

MVP (1 offer_id) — I will create it as a separate stable module, which can then be scaled to a list or the entire store.

Documentation, README, config, demo day with logs — included.

I am ready to start with the MVP and then expand to a full set of rules. Expand

Hello.

I am a NodeJS developer. I am ready to take on the task. Write to me, we will discuss.

Good day.

The technical specification is well-developed, and it is clear that you understand the business logic of auctions. However, the described functionality is a fully automated bidding service with logging, restrictions, error handling, and notifications.

With the current budget of 3000 UAH, it is only possible to implement an MVP for one offer_id:

- data retrieval via API
- basic logic of min_bid / max_bid / step
- scheduled execution
- logging to a file
- error handling with retries

Extended limits, reporting, Telegram notifications, protection against cyclical growth, and multi-products will require separate development.

I am ready to implement a compact, stable MVP within the specified budget. If full functionality is planned, I can offer a phased implementation.

I am ready to discuss the format. Expand

Good day, Yuri!

I have experience in developing automatic price and bidding management systems through API. I clearly understand the task — autobidder through Hotline Auctions API.

What I will implement:
1. Integration with Hotline Auctions API (API key, offer_id)
2. Logic for automatic bid increase (min/max/step, budget limit)
3. Scheduling launches (via cron or continuous monitoring)
4. Logging + demo in test mode

Python solution, possibly with Docker. Ready to start in 1-2 days. Let's discuss in private. Expand

Budget: 6000 UAH Deadline: 5 days

Hello.

I can implement the first stage of the project: an MVP service for automatic bid management through the Hotline Auctions API for one offer_id.

As part of the MVP, I will perform:
- obtaining current data for offer_id through the API;
- increasing/decreasing the bid according to the rules min_bid / max_bid / step;
- configuration of parameters: min_bid, max_bid, step, max_daily_budget, working_hours, schedule, pause_conditions;
- scheduled launches (every 5/10/15 minutes) and the possibility of manual launch;
- operation in the Europe/Kyiv time zone;
- logging of bid changes and API responses: timestamp, offer_id, old bid -> new bid, reason for change, API code/status, errors, and retry;
- retry, safe stop, protection against infinite growth (max N bid changes per hour, limit on total increase per day);
- secure storage of the API key through env, without outputting keys/tokens in logs;
- simple output of change history in CSV;
- README, configuration, and launch instructions;
- if necessary, launch in Docker.

An important point: I will first technically fix which metrics the API actually returns in your case. If the API does not return position, exact competitor bids, or CPC directly, then the management scheme is built on available metrics and API advices, and this is separately documented without unnecessary assumptions.

Deadline: 3–4 days for implementation + 1 day for test run with logs.

After receiving the API key, test offer_id, and parameters min/max/step/schedule, I can immediately start with a short API validation / proof of concept, and then bring it to a working MVP. Scaling to a list of products, all store products, and extended notifications can be done as a separate next stage. Expand

Hello! I can implement it. Write to me privately to discuss all the details. I will be happy to collaborate!

Good day.

I have experience in developing automated bidding management services through API (CPC/auction models), with min/max/step logic, budget constraints, retries, and protection against "circular growth."

I envision the architecture as follows:
Python service (or Node.js) + scheduler (cron) or Docker container,
config (yaml/json) with rules for offer_id,
logging in DB/CSV,
retry/backoff on API errors,
limits on the number of changes per hour and total growth per day,
Telegram/email notifications for critical events.

I suggest moving to private messages for clarification of details, assessment of timelines, and costs. Expand

Hello!
I can implement a service for automatic bid management through the Hotline Auctions API. The solution will be in Python, with the ability to configure rules (min/max/step, budget, working hours, etc.), logging, and notifications in Telegram/Email. MVP - management of one product, then it can be scaled to a list or the entire store. The implementation will be in a Docker container, with installation instructions and configuration for parameters.

✋ Hello! We are the IT company dZENcode.

We implement a service for automatic bid management through the Hotline API using Python or Node.js with flexible rule logic, logging, notifications, and secure key storage, relying on the team's experience, best practices, and our own developments.

Where is the deployment planned — VPS, Docker, or serverless?
Is a web admin panel needed, or is a config file sufficient for the MVP?

Hello! Your project looks wonderful. I am ready to start working immediately and complete it at a high level.

Budget: 3000 UAH Deadline: 14 days

I will develop a service for automating bid increases through the Hotline API, which will allow controlling positions in the search results and expenses. I will implement an algorithm with the ability to customize parameters for each product, including minimum and maximum bids, bid increments, target position, and daily budget.

I have experience working with APIs, particularly in automating business processes, and I am familiar with JavaScript, TypeScript, and Python. I have used similar approaches to optimize advertising in other projects, which allowed my clients to effectively manage their expenses and positions.

What specific conditions for stopping bid increases do you plan to implement? Do you need a separate interface for managing parameters?

Price: according to the project budget. Timeline: 2-3 weeks depending on the scope of work.

Budget: 7000 UAH Deadline: 7 days

interesting project, detailed technical specification. There is experience in various automation, interaction with various APIs. I develop in Python. I would be happy to collaborate.
