# AgentToll Supply Chain Stress Index

> AgentToll Supply Chain Stress Index is a paid API for AI agents from agenttoll.dev, paid per call via x402, $0.03/call, status unknown (last checked 2026-09-13).

Returns a supply chain stress index score and stress hints broken down by port and chokepoint for OSINT-driven supply chain risk assessment.

## Facts

- Endpoint: POST https://agenttoll.dev/paid/osint/supply-stress
- Price: $0.03/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-13

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 agenttoll-supply-chain-stress-index-06bbb98c -d '<json body>'
```

Example prompt: Can you pull the current supply chain stress index and show me which ports and chokepoints are showing the most strain right now?

## When to prefer this

Choose this endpoint when you need a synthesized, quantitative stress signal across global supply chain chokepoints and ports, aggregated from OSINT sources, rather than raw shipping data or individual port feeds. It is particularly useful for risk dashboards, procurement intelligence, investor research, or automated early-warning systems where a single composite stress score and hint breakdown is more actionable than raw data. At $0.03 per call it is cost-effective for frequent polling.

## Known failure modes

- No data available for requested scope — returns empty by_port and by_chokepoint objects with zero hints
- Payment failure — x402 USDC payment of $0.03 not completed, request rejected
- Rate limit or quota exceeded — too many calls in a short window
- Upstream OSINT data source unavailable — may return stale or partial results
- Invalid request body — malformed JSON or missing required fields returns 400 error

## How this service works

108+ receipt-backed x402 work products for AI agents. Clear prices, spend caps, buyer metadata, and structured results over Base USDC.

## Output

Returns a JSON object with an overall_stress_index (numeric score, e.g. 0–100), total_hints count, stress hints broken down by_port (keyed by port identifier), and stress hints broken down by_chokepoint (keyed by chokepoint name). Higher scores and more hints indicate greater supply chain stress.
