# Agent Demand Report — Uncovered API Requests

> Agent Demand Report — Uncovered API Requests is a paid API for AI agents from agentdata-api.sander-van-aard.workers.dev, paid per call via x402, $0.05/call, status unknown (last checked 2026-09-14).

Returns a 30-day aggregated report of what AI agents tried to pay for but couldn't find covered, based on rejected calls with payment presented, free-tier filings, and settled $0.01 intents at this provider.

## Facts

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 agent-demand-report-uncovered-api-requests-e1a65413 -d '<json body>'
```

Example prompt: Pull the 30-day demand report from the agentdata API — I want to see what kinds of API requests agents have been trying to pay for but couldn't find covered, broken down by category like coin, country, SMS, or monitor services.

## When to prefer this

Use this endpoint when you need a supply-side signal about what AI agents are actively trying to purchase but cannot, particularly within the x402 micropayment ecosystem. It is the only source for rejected-payment demand data aggregated at this provider. Prefer it over general market research when you want quantitative, payment-backed demand evidence rather than surveys or speculation. Not useful if you need network-wide demand data or individual transaction details.

## Known failure modes

- Payment not included or invalid x402 payment header — request rejected with 402
- Empty or malformed POST body — may return validation error
- No demand data available for the period — returns empty aggregates
- Network/worker downtime — connection timeout or 5xx error

## How this service works

What are agents asking for that they cannot buy yet, aggregated over 30 days. From our own measurements: calls we rejected on an uncovered value where the caller had already presented payment (kind is typically coin, country, vies_country, monitor_host or sms_service — free-form values possible), free requests filed by agents, and settled $0.01 intents. Demand at one provider, not a network-wide picture. Aggregates only: no wallets, no free text, no subject ids.

## Output

An aggregated JSON report covering the past 30 days of unmet agent demand at this provider: counts of rejected calls where payment was already presented (by kind such as coin, country, vies_country, monitor_host, sms_service, or free-form), free requests filed by agents, and settled $0.01 intents — all without any wallet IDs, free text, or subject identifiers.
