Nasdaq API Skill

Use this skill to fetch stock-universe data from Nasdaq's public screener endpoint and to ground API decisions in official Nasdaq Data Link docs.

Workflow

1. Confirm scope before calling APIs:

• If the task is stock screener rows/symbol lists, use scripts/nasdaq-screener.sh.
• If the task is product/API selection, auth, or limits, read references/api_docs.md first.

2. Use the CLI instead of ad-hoc curl when possible:

• Run scripts/nasdaq-screener.sh --help for options.
• Start with --limit and --offset for deterministic pagination.
• Use --format symbols for ticker-only output, or --format rows for JSON row objects.

3. Handle reliability constraints:

• Include browser-like headers (script does this by default).
• Prefer retries in caller workflows for transient failures.
• Keep requests paced; avoid burst loops.

4. Validate result shape before downstream logic:

• Expect top-level data.rows for screener queries.
• Fail fast if status.bCodeMessage is present or data.rows is missing.
