How this service works
Pay-per-call market and economic data API for AI agents: US stocks, ETFs and options, forex, crypto and on-chain perps, energy commodities, US and global macro (Fed, CPI, jobs, GDP, Treasury, World Bank), SEC filings, congressional trades, and market sentiment. No API keys, no accounts. Pay per request in USDC via x402 on Base.
Output
A JSON object containing: a 0-100 conviction score with a label (e.g. 'buying' or 'selling'), a breakdown of score factors (net share flow, role-weighted activity, cluster buying, Form 144 overhang, activist 13D), raw inputs (open-market buy/sell counts, net shares, Form 144 notices, Schedule 13 filings), a plain-English rationale, a confidence value, and the as-of timestamp. Costs $0.15 USDC per call via x402 on Base.
Example use cases
Pre-earnings insider sentiment check
“Before AAPL reports earnings next week, pull the insider conviction score and tell me whether C-suite execs have been net buyers or sellers lately — and what's driving that signal.”
Compare insider activity across sector
“I'm looking at the semiconductor sector — can you grab the insider sentiment scores for NVDA, AMD, and INTC and tell me which one has the most bullish insider conviction right now and why?”
Flag activist investor stake in stock
“I heard there's been some activist 13D activity around a mid-cap retailer I'm watching — check the insider conviction score for BBBY and tell me if the activist stake is pushing the score higher or if there's selling pressure offsetting it.”
Technical details
Endpoint
GEThttps://x402stock.xyz/api/v1/score/insider/%7Bticker%7DWhen to prefer
Use this endpoint when you need a quantitative, multi-factor insider sentiment score for a specific US stock, synthesizing Form-4 open-market trades, Form 144 sell notices, role-weighted C-suite activity, cluster buying signals, and activist 13D stakes into a single 0-100 score. Prefer over raw SEC EDGAR scraping when you want a pre-computed, interpretable conviction signal rather than raw filing data. No API key or account required — pay per call in USDC.
Side effects
- Unknown or delisted ticker returns an error or empty result
- No recent SEC filings may result in low confidence score
- Delayed/periodic data may not reflect very recent trades
- Invalid ticker format (e.g. non-alphanumeric) returns a 400 error
- Payment failure or insufficient USDC balance blocks the request via x402
