Parsing large price fluctuations on dex through the free geckoterminal api

Budget: 400 USD Deadline: 6 days

Hello!
I am implementing an asynchronous service in Python for parallel price monitoring through 100+ proxies. I will set up batch requests, spike analytics (5/30 min), and instant notifications in Telegram. I will ensure stable operation with the database and reliable bypassing of CoinGecko limits.

Budget: 600 USD Deadline: 10 days

I can take on the implementation.

How I see the solution:

Architecture

Module for obtaining a complete list of tokens from the CoinGecko API → saving in JSON once an hour

Price parser:

iterating through tokens in batches of 30 tokens

requests to the most liquid pools

parallel execution using 50–100 proxies

limit: 1 request/second from each proxy

Database (PostgreSQL):

constant price recording

history of changes

Analytical module:

checking changes of 30 / 50 / 100%

for different intervals: between updates, 5 min, 30 min (and others — can be flexibly configured)

Telegram notifications upon detecting anomalous changes

Logging and protection against duplicates / API errors

Technologies

Python (asyncio)

aiohttp / httpx

Proxy rotation

PostgreSQL

Telegram Bot API

Cron / worker

Timeline

Basic system (collection, proxy, DB, alerts): 10–14 days

Fine-tuning the analysis logic to precise criteria: +2–4 days

Cost

$600–900, depending on:

final complexity of the analytics,

volume of tokens,

number of proxies and load.

I suggest starting with an MVP, and refining the detailed analysis criteria (percentages, time windows) at the end — as you plan.
I am ready to discuss the details and start immediately. Expand

Good day!

I have significant experience with EVM blockchain/web3, worked with DEXes, write contracts, worked on a HyperEVM trading project.

I will do it with minimal latency, let's discuss!

Budget: 300 USD Deadline: 3 days

Hello. I will do it in php+mysql. I will say right away that the first free proxies that come along will not work. Here, we need to be realistic. Feel free to reach out.

Budget: 450 USD Deadline: 7 days

Good day. I recently developed a similar script, but for CEX. I can redo it for DEX. I will be waiting in private messages to discuss the details.

Hello! Do you need to record data only from the most liquid pools, or is it preferable to include all available ones? Regarding the budget and deadlines, I can provide more precise information in personal correspondence.

1. I will use the Coingecko API to obtain a list of all tokens and will store this information in JSON format every hour.
2. Using a parser, I will work with the JSON file, iterating through all tokens one by one, 30 tokens per batch request, to get prices in the most liquid pools.
3. I will store all prices in a database and analyze them based on certain criteria. If the price changes by 30-50-100% from the last update or if it changes by 30-50-100% within 5 minutes, 30 minutes, etc., I will send you a message on Telegram.

Thank you for considering my proposal. I look forward to the opportunity to collaborate with you!
