How this service works
Historical revealed signal snapshots (commit-reveal hash chain): past BUY/SELL/HOLD + confidence across major pairs, each with its verifiable hash. Bulk pay-per-call data for AI agents (USDC on Base).
Output
Returns a JSON object containing a count of records, a list of historical signal entries each with a hash, timestamp, sequence number, previous hash reference, and an array of signals per trading pair (including pair name, signal direction BUY/SELL/HOLD, and confidence score), plus a generated_at timestamp.
Example use cases
Example prompt
“Show me the historical BUY/SELL/HOLD trading signals for BTC/USD — I want to see past signals with their confidence scores so I can review the recent market-state history.”
Technical details
Endpoint
GEThttps://signals.nsgoods.org/historyWhen to prefer
Choose this endpoint when you need a tamper-evident, chained historical log of crypto market-state signals (BUY/SELL/HOLD) with confidence scores, especially for backtesting, auditing signal history, or reviewing past trading recommendations. Prefer this over real-time signal endpoints when historical context and sequence integrity (via hash chaining) are important.
Side effects
- 402 Payment Required if x402 payment on Base is not included or fails
- No history returned if no signals have been generated yet
- Malformed response if payment is accepted but upstream Kraken data is unavailable
- Rate limiting or access denial if payment is invalid or insufficient (0.05 USDC per call required)
- Empty history array if the requested time range has no signals
