# What's new in v2

> Every change in AgentSource v2: structural conventions, new Research endpoints, renamed fields, removed response fields, and new limits.

<Info>
  **Beta.** AgentSource v2 is in beta. Details may still change before GA.
</Info>

## Structural changes

| Change                         | Detail                                                                               |
| :----------------------------- | :----------------------------------------------------------------------------------- |
| **Path versioning**            | Every endpoint moves under `/v2`, replacing its `/v1` equivalent                     |
| **No bulk endpoints**          | A single endpoint accepts one ID or a list of IDs; `/bulk_enrich` routes are removed |
| **Sync/async pairing**         | Every enrichment exposes `.../enrich` and `.../job`                                  |
| **Autocomplete consolidation** | One `/v2/autocomplete` endpoint replaces the per-entity autocomplete routes          |

## New capabilities

* **[Research (GenAI) endpoints](/v2/endpoints/research)** — custom AI-powered research over businesses or prospects, with a caller-defined `output_schema` and optional real-time web grounding.
* **[Async job infrastructure](/v2/async-jobs)** — shared job submission, status, and result retrieval behind every `.../job` endpoint.
* **[Contact information waterfall](/v2/prospects/enrichments/contact_information_job)** — the async contact endpoint can fall back to a verified external provider for prospects Explorium data cannot enrich, with per-result source tagging.

## Signal fixes

Misspelled field names corrected in v2:

| Endpoint / feature                                                                  | Current (typo)                                                 | Correct in v2        |
| :---------------------------------------------------------------------------------- | :------------------------------------------------------------- | :------------------- |
| `POST /v2/businesses/events` → `new_funding_round` payload                          | `founding_stage`                                               | `funding_stage`      |
| `POST /v2/businesses/events` → `new_funding_round` payload                          | `founding_date`                                                | `funding_date`       |
| `POST /v2/prospects/contact_information/enrich` → `ContactsInformationOutputSchema` | `professions_email` (title "Professions Email", format: email) | `professional_email` |

## Renamed

| v1                              | v2                    |
| :------------------------------ | :-------------------- |
| `contacts_information` endpoint | `contact_information` |

## Removed fields

<Warning>
  These are breaking changes for any consumer reading the fields below.
</Warning>

* `entity_id` — no longer returned for enrichments
* `display_name` — removed from the business `linkedin_posts` enrichment response
* Address signals removed from the `company_ratings_by_employees` enrichment:
  * `company_city`
  * `company_country_code`
  * `company_region`
  * `company_street`
  * `company_zip_code`

## Changed defaults and parameters

* The `size` parameter is **removed** from pagination in fetch. The default stays 60K.
* `include_operating_locations` in business fetch now defaults to **`false`**.

## New limits

| Limit                       | Value              |
| :-------------------------- | :----------------- |
| Async enrichment input size | Max 10,000 records |
| Async job run time          | Max 24 hours       |
