How this service works
Explore 230 pay-per-use x402 APIs and 27 agent-native digital products, with Base USDC service pricing, Polar checkout, and free discovery.
Output
Returns a JSON object with a validation result field containing the assessment of the OHLCV data, a warnings array listing any detected issues or anomalies, an evidence_scope field indicating the source of the evaluated data, a status field ('succeeded'), and a full receipt including payment ID, network, execution metadata, and a SHA-256 hash of the result for auditability.
Example use cases
Pre-backtest data quality check
“Before I run my backtest, can you validate this OHLCV data I pulled from my broker and let me know if there are any bad candles or data integrity issues I should fix?”
Detect inverted high-low candles
“I think some of my historical candlestick data has high values lower than the low values — can you run it through your OHLCV validator and tell me which candles are flagged?”
Verify third-party market feed data
“I just received this candlestick data from a third-party market data vendor — can you validate the OHLCV values to make sure they're internally consistent before I import them into my trading system?”
Technical details
Endpoint
POSThttps://signalharness.ai/api/agent/services/ohlcv_validate/invoke?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, pay-per-call, agent-native validation of OHLCV financial data with cryptographic receipts and on-chain payment settlement. Ideal for trading bots, backtesting pipelines, or data ingestion workflows that need programmatic, verifiable quality checks on candlestick data without spinning up custom validation logic. Prefer over manual checks or generic data validators when auditability via receipt hash is important.
Side effects
- Empty or malformed ohlcv_validation_request string returns a validation error
- Input exceeding 65536 characters is rejected
- Network or payment failure on Base (eip155:8453) results in failed status
- Ambiguous or non-parseable market data may produce inconclusive validation output
- Service downtime returns a non-200 response with no receipt
