## How to call it through Zero

```sh
zero fetch --capability postcode-context-uk-bulk-batch-enrichment-aabbccab
```

Example prompt: Can you pull demographic and property intelligence for these 50 UK postcodes — SW1A 1AA, EC1A 1BB, W1A 0AX, M1 1AE, B1 1BB — and give me the full enrichment for each one?

## When to prefer this

Choose this endpoint when you need to enrich multiple UK postcodes simultaneously (up to 50) in a single API call, rather than making individual lookups. Ideal for bulk CRM enrichment, batch address processing, cohort analysis, or any workflow where efficiency at scale matters. Use the single-postcode or compare endpoints for smaller or comparative tasks.

## Known failure modes

- More than 50 postcodes submitted — request rejected or truncated
- Invalid or malformed postcode format — individual postcode entries may return errors or null data
- Non-UK postcodes submitted — unrecognised and likely return null or error
- Empty postcodes parameter — returns validation error
- Network timeout for very large batches close to the 50-postcode limit

## How this service works

POST /api/v1/batch — Bulk UK Postcode Demographics & IMD Enrichment (1 to 50 postcodes with cohort aggregation and spatial summaries)

## Output

A structured batch response containing demographic, property, and socio-economic enrichment data for each of the submitted UK postcodes, including cohort synthesis across all postcodes in the batch — up to 50 postcodes processed in a single response.
