# 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.
