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.

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.

Write, we will do everything. There is a similar case with price change analysis and notifications in Telegram.

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!

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.

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!
