Predictions
Meta-model Historical
The endpoint GET /v2/prediction/metamodel/historical returns the 10,000 paths of the variance-based weighted meta-model (not based on the meta-leaderboard but on miner contributions, cf https://github.com/synthdataco/synth-subnet/blob/main/research/synth_metamodel_paper.pdf)
Usage
The main usage is to backtest strategies.
Fetch the prompts
GET /validation/prompts: it returns the start time of the prediction one which we can perform a backtestFetch the historical meta-model
GET /v2/prediction/metamodel/historical
Endpoint definition
GET /validation/prompts
time_increment
int
The increment of time between prompts in seconds (e.g., 300 for 24h horizon and 60 for 1h horizon).
time_length
int
The time length of the predictions in seconds (e.g., 86400 for the 24h horizon and 3600 for the 1h horizon).
asset
string
The asset for which the data is being requested (BTC, ETH, SOL, HYPE, XRP, XAU, SPY, NVDA, GOOGL, TSLA, AAPL).
from
string
The start date for the data in ISO format (e.g., 2026-03-02).
to
string
The end date for the data in ISO format (e.g., 2026-03-31).
GET /v2/prediction/metamodel/historical
asset
string
The asset identifier, such as XAU for gold.
prompt_name
string
The name of the prompt frequency to use, such as 'low' for the 24h horizon and 'high" for the 1h horizon
start_time
string
The starting time for the prediction in ISO format (e.g., 2026-04-10).
Prediction Historical
Returns historical predictions for backtesting.
Parameters
asset
string
The asset identifier.
miner
int
The ID of the miner.
start_time
string
The starting time in ISO format (e.g., 2026-03-09).
time_increment
int
The time increment in seconds (e.g., 60).
time_length
int
The duration of the prediction in seconds (e.g., 3600).
Example: curl -L 'https://api.synthdata.co/v2/prediction/historical?asset=BTC&miner=198&miner=200&miner=39&start_time=2026-03-09&time_increment=60&time_length=3600' -H 'Authorization: Apikey ...'
Usage
Typical usage is to fetch the historical meta-leaderboard and then the historical predictions of the top miners.
curl -L 'https://api.synthdata.co/v2/meta-leaderboard/historical?start_time=2026-01-09T00%3A00%3A00Z&prompt_name=high'
