# Demand Radar

> Demand Radar is a paid API for AI agents from scanpay-edge.alextaghiashvili.workers.dev, paid per call via x402, $0.005/call, status unknown (last checked 2026-11-02).

Aggregates anonymized demand telemetry from x402 API traffic logs to reveal which endpoints are being called, challenged, and paid for, guiding build/buy decisions.

## Facts

- Endpoint: GET https://scanpay-edge.alextaghiashvili.workers.dev/api/v1/demand-radar?utm_source=zero.xyz
- Price: $0.005/call
- Payment: x402
- Status: unknown
- Last checked: 2026-11-02
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/demand-radar-500cf0fc
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_rVwP4IMjEMrNa8ahbF6rx

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 demand-radar-500cf0fc
```

Example prompt: Pull the demand radar report for the last 24 hours — I want to see which API paths are getting the most 402 challenges and which ones are actually converting to paid calls.

## When to prefer this

Use this endpoint when you need anonymized, aggregated demand intelligence about x402 API traffic — specifically to understand which paths are challenged vs paid, which agents are calling them, and which products are generating revenue. Prefer it over raw log analysis when you need a quick, structured summary without identifying individual users.

## Known failure modes

- Invalid window_hours value may return a default or error
- No traffic in the window returns zeroes across all fields
- Payment failure (402 not resolved) blocks access to the data
- Stale or incomplete traffic ingestion may undercount recent events

## How this service works

Pay-per-call x402 APIs for AI agents: OpenAI-compatible LLM chat, perp funding and arbitrage spreads, crypto prices, gas, FX, Solana SPL mint audit, token price by contract, x402 delivery-receipt verification, web search, clean page extraction, batch tools and deterministic code-security scanning. USDC on Base or Solana, no signup, no API key, from $0.0001 a call.

## Output

Returns a JSON object with total HTTP 402 challenge counts, per-path breakdowns (path, challenges, payment_attempts), per-user-agent breakdowns, and a list of paid products with delivery counts — all aggregated from anonymized traffic logs over the requested time window.
