I need a complete historical extract from Betfair covering every horse racing and greyhound racing market between 1 Jan 2022 and 11 May 2026. The file (or files, one per year) must be in CSV format and contain every standard Betfair header, all available price ladders, and a one-minute snapshot of each runner’s odds with an accompanying timestamp column. I am only interested in WIN markets, but I want them from every country Betfair lists—no geographic filtering. You will have to source the data through your own Betfair Historical Data or Streaming API (free from Betfair) subscription; without an active key this task cannot be completed. To confirm you have access and the structure matches what I expect, send me a small sample (a dozen rows is fine) before we move to full extraction. Deliverables will be considered complete when: • The full date range is covered with no gaps • Each CSV opens cleanly and matches the sample format • Columns include: all standard headers, selection odds for every price point captured at one-minute granularity, and an explicit timestamp field If you normally work in Python, R, or a similar toolset please mention it—it helps me understand how you’ll automate the pull and verify integrity.

The Betfair API rate limits historical pulls, so batching by date range and market type is the right approach. I would pull catalogue data plus prices and volumes for both horse racing and greyhound markets into clean daily CSVs. I can start today and deliver a working script in 2 days. Bid and timeline reflect the post as written. Once I know the date range you need, the final numbers may shift. Want to jump on a quick call?

Hi, this project requires precise historical data extraction from Betfair’s API with comprehensive coverage and strict formatting requirements. The main engineering risk lies in orchestrating reliable, gap-free ingestion of minute-by-minute odds snapshots at scale across multiple years and geographies. I usually structure data pipelines to separate extraction, validation, and output formatting layers to ensure integrity and maintainability. I’ve built several systems that automate complex data pulls and transform them into consistent, analyzable formats. My experience with Custom Feature Development & Integration and NYSE Day Trading Bot Development highlights my ability to handle large-scale API data extraction and produce clean, validated outputs. I recommend designing the pipeline to include robust error detection and schema validation to accommodate any Betfair API changes over time. Systems like these must be built for long-term reliability and clarity, with automated checks for completeness and timestamp consistency. I can start by outlining the retrieval pipeline and reviewing the CSV chunking strategy to ensure clean yearly splits and full coverage. Thanks, Hercules

Hello, I understand you need a complete historical Betfair extract for all horse racing and greyhound WIN markets from 1 Jan 2022 to 11 May 2026, including one-minute odds snapshots, full standard Betfair headers, timestamps, and no missing coverage across all countries listed on Betfair. You also require an initial sample dataset before full extraction to validate format and structure. I can build a fully automated data pipeline using Python with the Betfair Historical Data/Streaming API to extract, structure, and normalize market data into clean yearly CSV files. The system will capture one-minute interval snapshots of all runners’ odds, ensure consistent timestamping, filter WIN markets only, and validate data completeness across the full date range. I will also ensure schema consistency with standard Betfair headers and provide a sample extract (dozen-row dataset) for approval before scaling the full historical pull. I’m ready to start by setting up API authentication, defining the extraction schema, and generating the sample dataset for your confirmation. Once approved, I will proceed with full historical backfill and integrity checks to ensure no gaps in coverage. Thanks, Asif

Hi, I can help extract and prepare the Betfair historical WIN market data for horse racing and greyhound racing from 1 Jan 2022 to 11 May 2026 in clean CSV format. I have strong experience with Python data pipelines, API extraction, large CSV generation, data validation, price ladder parsing, timestamp normalization, and integrity checks across large date ranges. I can automate the pull by year, filter only WIN markets, include all countries available in Betfair, and generate one-minute runner odds snapshots with the required timestamp field and standard Betfair headers. Before full extraction, I can provide a small sample CSV with around a dozen rows so you can confirm the structure, headers, price ladders, and timestamp format. After that, I will run the full extraction, split files by year if preferred, verify there are no date gaps, and ensure each CSV opens cleanly. I will use Python scripts with clear logging so the process is repeatable and auditable. Best, Justin

Hello there, I’ve built robust data pipelines for large historical datasets and complex market data, focusing on accuracy, completeness, and repeatable exports. I’m an independent developer skilled in PHP, API integration, web scraping, and data processing, with a practical approach to turning Betfair-like data into clean CSVs and reliable verification checks. In past work I’ve extracted structured market data, produced per-market CSVs with full headers, timestamps, and multi-price ladders, and verified integrity against sample outputs. I’ll design a repeatable pull-and-validate workflow that pulls across the full 2022-2026 window, includes all WIN markets from all Betfair regions, and outputs one file per year with one-minute-interval odds snapshots and explicit timestamps. I can handle this end-to-end using PHP, with automated validation steps and a deliverable-ready CSV suite. The plan includes an initial sample (around a dozen rows) to confirm structure before full extraction, then a full rollout with checks for gaps and clean CSV opens. Best regards, Billy Bryan
