## Available tools

| Tool | What it does | Cost and limits |
| - | - | - |

| `listDatasetTables` | Lists the available dataset tables. | Free |
| `getTableDetails` | Returns the columns and constraints for one table. | Free |
| `getQueryExamples` | Returns example queries by research category. | Free |
| `previewData` | Runs a read-only SQL query for analysis and previews. | Free; up to 15 rows per response and 1,000 preview rows in a rolling 24-hour period |
| `exportData` | Creates a downloadable CSV from a read-only query. | 1 credit per exported row; up to 1,000 rows |
| `unlockPersonEmail` | Retrieves a verified email for one person when available. | Up to 5 credits; repeat unlocks for the same account cost 0 |
| `unlockPersonEmails` | Retrieves verified emails for an explicitly bounded batch of 1–20 people. | Up to 5 credits per new email; free outcomes use 0 |

## Previews, exports, and approval

Fundable separates research from paid retrieval:

* Analytical previews are free and return at most 15 rows at a time.
* Preview queries are read-only and cannot modify the dataset.
* A CSV export happens only after you explicitly request a file or download and
  approve a maximum credit amount.
* Exports support up to 1,000 rows, 25 columns, 4,096 bytes per cell, and 10 MB per
  file. A result above your approved ceiling or a file limit is rejected without a
  charge.
* Retrying identical export SQL within 15 minutes recovers the same export without a
  second charge.
* Email unlocks require explicit approval. Missing emails, invalid identifiers,
  duplicates, and emails previously unlocked by the same account use 0 credits.

<Tip>
  Begin broad research with a free preview. Ask for a CSV only after the filters and
  columns look right.
