# x402stock Stock Backtest with PNG Report > x402stock Stock Backtest with PNG Report is a paid API for AI agents from agents.x402stock.xyz, paid per call via MPP, $0.5/call, status unknown (last checked 2026-09-10). Runs an SMA crossover or RSI mean-reversion backtest on a US stock ticker over up to 5 years of daily history and returns performance statistics plus a hosted equity-curve PNG report. ## Facts - Endpoint: GET https://agents.x402stock.xyz/api/v1/backtest/{ticker} - Price: $0.5/call - Payment: MPP - Status: unknown - Last checked: 2026-09-10 - Activations on Zero: 0 - Provider: agents.x402stock.xyz - Website: https://agents.x402stock.xyz - Canonical page: https://www.zero.xyz/c/agents-x402stock-xyz-x402stock-stock-backtest-with-png-report-24a0fe0b - Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_Zq6XEbV_Drc30iNRzDczi Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently. ## How to call it through Zero Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`): ```sh zero fetch --capability agents-x402stock-xyz-x402stock-stock-backtest-with-png-report-24a0fe0b ``` Example prompt: Run a backtest on AAPL using the SMA crossover strategy with a 50-day fast and 200-day slow moving average over the last 3 years, starting with $10,000 capital, and give me the performance stats and equity curve chart. ## When to prefer this Choose this endpoint when you need a quick, no-setup quantitative backtest of a classic technical strategy (SMA crossover or RSI mean-reversion) on a US-listed stock or ETF, and want both machine-readable statistics and a shareable visual equity curve PNG in a single call. It is ideal for agents that need to evaluate strategy viability, compare against buy-and-hold, or generate a report artifact without running their own backtesting infrastructure. Prefer alternatives if you need custom strategies beyond SMA cross or RSI reversion, intraday data, or multi-asset portfolio-level backtests. ## Known failure modes - Unknown or delisted ticker returns a 404 or error response - Strategy parameter conflicts (fast >= slow for SMA) may cause a validation error - Insufficient historical data for the requested years returns partial or error response - years parameter exceeding 5 is rejected - Invalid strategy enum value returns a 400 bad request - Payment not processed via x402 returns a 402 Payment Required - Artifact URL expires after the stated expiry time and becomes inaccessible ## How this service works Backtests a simple rule on a US stock and returns a finished report PNG. Runs an SMA crossover (?strategy=sma_cross&fast=50&slow=200) or RSI mean-reversion (?strategy=rsi_reversion&period=14&lower=30&upper=70) over daily history (?years=, max 5), no lookahead, rendered as an equity curve vs buy & hold. Returns full stats plus a hosted `artifact.png_url`. From x402stock ## Output Returns a JSON object containing: a hosted PNG artifact URL (equity curve vs buy-and-hold, expires after a set time), strategy metadata (kind, label, parameters), full performance stats (total return, Sharpe-equivalent metrics, max drawdown as available), trade-level detail (count, win rate, average/best/worst return per trade, full trade list), buy-and-hold comparison stats, the date range and bar count used, and a disclaimer. The PNG is accessible via the artifact.url field. ## Request schema (JSON Schema) ```json { "type": "object", "required": [ "ticker" ], "properties": { "fast": { "type": "integer", "default": 50, "maximum": 200, "exclusiveMinimum": 0 }, "slow": { "type": "integer", "default": 200, "maximum": 400, "exclusiveMinimum": 0 }, "lower": { "type": "number", "default": 30, "maximum": 99, "minimum": 1 }, "upper": { "type": "number", "default": 70, "maximum": 99, "minimum": 1 }, "years": { "type": "number", "default": 3, "maximum": 5, "exclusiveMinimum": 0 }, "period": { "type": "integer", "default": 14, "maximum": 100, "exclusiveMinimum": 0 }, "ticker": { "type": "string", "description": "US-listed ticker symbol (uppercase), e.g. AAPL." }, "capital": { "type": "number", "default": 10000, "maximum": 1000000000, "exclusiveMinimum": 0 }, "strategy": { "enum": [ "sma_cross", "rsi_reversion" ], "type": "string", "default": "sma_cross" } } } ``` ## Response schema (JSON Schema) ```json { "type": "object", "required": [ "ticker", "source", "as_of", "artifact", "strategy", "data", "disclaimer" ], "properties": { "data": { "type": "object", "required": [ "bars", "start_date", "end_date", "initial_capital", "strategy", "buy_hold", "trades" ], "properties": { "bars": { "type": "number" }, "trades": { "type": "object", "required": [ "count", "win_rate_percent", "avg_return_percent", "best_percent", "worst_percent", "list" ], "properties": { "list": { "type": "array", "items": { "type": "object", "propertyNames": { "type": "string" }, "additionalProperties": { "anyOf": [ { "type": "number" }, { "type": "string" }, { "type": "null" } ] } } }, "count": { "type": "number" }, "best_percent": { "type": "number" }, "worst_percent": { "type": "number" }, "win_rate_percent": { "type": "number" }, "avg_return_percent": { "type": "number" } }, "additionalProperties": false }, "buy_hold": { "type": "object", "propertyNames": { "type": "string" }, "additionalProperties": { "type": "number" } }, "end_date": { "anyOf": [ { "type": "string" }, { "type": "null" } ] }, "strategy": { "type": "object", "propertyNames": { "type": "string" }, "additionalProperties": { "type": "number" } }, "start_date": { "anyOf": [ { "type": "string" }, { "type": "null" } ] }, "initial_capital": { "type": "number" } }, "additionalProperties": false }, "as_of": { "type": "string" }, "source": { "type": "string", "const": "x402stock" }, "ticker": { "type": "string" }, "artifact": { "type": "object", "required": [ "id", "url", "format", "expires_at" ], "properties": { "id": { "type": "string" }, "url": { "type": "string" }, "format": { "type": "string", "const": "png" }, "expires_at": { "type": "string" } }, "additionalProp … (truncated) ``` ## More - Live health (JSON, refreshed every minute): https://www.zero.xyz/c/agents-x402stock-xyz-x402stock-stock-backtest-with-png-report-24a0fe0b/health.json - [Zero catalog index](https://www.zero.xyz/llms.txt) - [Other services from agents.x402stock.xyz](https://www.zero.xyz/host/agents.x402stock.xyz/llms.txt)
