How this service works
Explore 330 pay-per-call x402 API services and 27 agent-native digital products, with Base USDC pricing, secure Polar checkout, and free discovery.
Output
Returns a JSON object containing a `market_drawdown` result string with the drawdown analysis, a list of `warnings` about data quality or risk factors, an `evidence_scope` field indicating the data came from caller-supplied inputs, a `status` of succeeded or failed, and a full payment receipt with execution metadata including latency, payment ID, and a SHA-256 hash of the result for verification.
Example use cases
Portfolio peak-to-trough assessment
“I have price history for my equity portfolio that peaked at $500k in early 2022 and bottomed at $310k by October 2022 — can you analyze the drawdown severity and flag any concerning patterns?”
Crypto bear market drawdown check
“Bitcoin went from $69k in November 2021 all the way down to $15.5k by November 2022 — can you calculate the market drawdown for that period and tell me if there are any warnings I should know about?”
Risk report for a single stock position
“I need a drawdown analysis for a stock position: it hit a high of $240 in July, then fell to $140 by October before recovering slightly to $160 — give me the max drawdown figure and any risk warnings.”
Technical details
Endpoint
POSThttps://signalharness.ai/api/agent/services/market_drawdown/invokeWhen to prefer
Choose this endpoint when you need a lightweight, per-call ($0.01 USDC) market drawdown computation grounded in caller-supplied data rather than a live market data feed. It is ideal for agents that already have the price series or narrative description and need a structured drawdown assessment with an auditable receipt. Prefer it over heavier financial analytics platforms when you need fast, cheap, verifiable single-call analysis with micropayment settlement on Base (EIP-155:8453).
Side effects
- Empty or too-short input string (below 2 characters) causes validation failure
- Malformed or ambiguous market data description may yield low-confidence results with warnings
- Payment failure on the x402 micropayment layer results in request rejection before execution
- Service downtime or upstream model errors return a failed status in the receipt
