How this service works
Ai for 500 provides evidence-backed market intelligence for the emerging AI-agent economy. Market Check costs $0.05 USDC per request through x402.
Output
A JSON object containing: a plain-English summary recommendation, an assessment label (e.g. GO, WATCH, STOP), a confidence score (0–1) reflecting evidence sufficiency, a numeric decision score (0–100), tracked competitor count, median call volume over 30 days, median payer signal over 30 days, and usage evidence coverage percentage.
Example use cases
Pre-launch offer validation for indie maker
“Before I spend another month building, can you check if there's actual market evidence for a subscription-based AI meeting summarizer aimed at remote teams — give me the assessment and confidence score so I know whether to keep going.”
Competitive landscape check for AI startup
“How saturated is the market for AI-powered customer support chatbots right now? I want to see how many competitors are being tracked and what the payer signal looks like before we pitch investors.”
Budget allocation decision for product pivot
“We're thinking of pivoting our agent to focus on AI-driven expense categorization for freelancers — can you pull a market check on that offer so I can see the decision score and whether the evidence says WATCH, GO, or STOP?”
Technical details
Endpoint
POSThttps://aifor500.com/api/market-check.phpWhen to prefer
Choose this endpoint when you need a fast, quantitative market signal grounded in actual usage and payer data for the AI-agent economy specifically — not general web sentiment or survey data. It is especially useful for pre-launch validation, resource allocation decisions, and competitive scoping within the agent/AI tooling space. Prefer it over generic market research APIs when you want a scored, evidence-backed go/no-go output with explicit confidence framing.
Side effects
- Insufficient market data for a very novel or narrow niche may yield low evidence coverage and a low confidence score
- Vague or overly broad product descriptions may produce less actionable assessments
- Payment failure (insufficient USDC balance or x402 protocol error) will prevent the request from completing
- Rate limiting or service unavailability may return non-200 responses
