How this service works
Pay-per-call tools for people building AI agents: live web search and page contents, point-in-time crypto market data and news for backtests (no lookahead), verifiable track records of 1,000 crypto strategies locked on the Base network, company profiles, quick AI and batch prices. Ask us to turn a public website into a JSON endpoint. Pay per call, no account, free trial.
Output
Returns a JSON object with the strategy ID, an array of rows (each containing a period timestamp, the on-chain commit transaction hash, stamped signal calls, computed signal calls, and the return percentage for that period), total periods checked, count of identical periods, and an overall match rate between 0 and 1 indicating what fraction of periods reproduced exactly.
Example use cases
Auditing a crypto strategy before investment
“Before I allocate capital to strategy CRY-1h-042, can you reproduce its track record for the past 30 days and tell me if the signals actually match what was committed on-chain? I want the match rate and daily returns.”
Verifying a strategy vendor's claimed returns
“A strategy provider is claiming 95% accuracy for CRY-5m-005 over the last week. Can you independently verify that by reproducing the track record from 2024-06-01 to 2024-06-07 and checking if the stamped signals match the computed ones?”
Regular integrity check in an automated agent workflow
“Every Monday, run a reproduce check on strategy STK-1d-012 for the previous 7 days and alert me if the match rate drops below 0.95 — I need to know if the signals are still lining up with what was committed on-chain.”
Technical details
Endpoint
GEThttps://api.manylives.me/paid/trackrecord/reproduce?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need cryptographic, on-chain proof that a trading strategy's historical signals were committed before execution — not just self-reported backtests. Prefer this over generic backtesting tools when auditability and tamper-evidence matter, such as before allocating capital to a third-party strategy or when a regulatory or compliance context requires verifiable track records locked on the Base blockchain.
Side effects
- Missing or invalid strategy ID returns an error — the 'id' query parameter is required
- Strategy ID not found in the registry returns a 404 or empty result
- Date range too large may result in slow response or truncated data
- Invalid date format for 'from' or 'to' (must be YYYY-MM-DD) causes a validation error
- Payment of $0.02 USDC not provided or x402 flow not completed results in 402 Payment Required
- Network or blockchain unavailability may cause on-chain commit lookup to fail
