Example prompt: Can you pull the current U.S. federal Failure to Deliver threshold securities list for me? I want to see which tickers are flagged right now.

## When to prefer this

Use this endpoint when you need programmatic, pay-per-call access to the U.S. federal Failure to Deliver threshold securities list and can pay in USDC on Base via x402. Prefer this over scraping SEC/FINRA websites directly when you want a clean API interface and are already integrated with the x402 micropayment protocol.

## Known failure modes

- Payment not settled in USDC on Base — returns 402 Payment Required
- x402 facilitator unreachable — payment cannot be processed
- No data available for current period — empty or error response
- Rate limiting or server unavailability on Render hosting — 503 Service Unavailable
- Malformed request missing required HTTP method field — 400 Bad Request

## How this service works

Pay-per-call crypto, RWA, federal, SEC, Section 8/HUD housing, and compliance APIs via x402. Primary: USDC on Base (eip155:8453). Also accepts Global Dollar (USDG) on Robinhood Chain (eip155:4663) via sovereign X-PAYMENT-TX. Hyphen routes only (e.g. /x402/gas-tracker, /x402/pha-lookup, /x402/sec-8k). MARKETPLACE REVIEW: use free /x402/playground/* (no key, no payment). Production /x402/* returns 402 unless paid via x402 or X-Api-Market-Key / X-API-Key from seller dashboard.

## Output

A list of U.S. securities currently on the Failure to Deliver (FTD) threshold list, typically including ticker symbols, security names, and threshold status as sourced from federal data. Payment of $0.02 USDC on Base is required per call via x402 protocol.
