> Browse and search course articulation agreements between California Community Colleges and UC/CSU institutions on ASSIST.org. Look up which CCC courses satisfy transfer requirements for a given major and receiving university, or retrieve articulation data across all participating colleges.

**Category:** Education | **Website:** [www.assist.org/](https://www.assist.org/) | **Docs:** [parse.bot/marketplace/861ca057-4fed-425d-a01c-1df24205f53a/assist-org-api](https://parse.bot/marketplace/861ca057-4fed-425d-a01c-1df24205f53a/assist-org-api)

Pay-per-use API proxy for Locus Pro. Each call burns credits from your workspace balance.

## Access

**Base URL:** `https://api.paywithlocus.com/api/wrapped/credits/assist/`
**Auth:** `Authorization: Bearer <LOCUS_CREDITS_SECRET_KEY>` (an `lcr_` secret key or a scoped `lcac_` agent credential)
**Required header:** `Idempotency-Key: <fresh UUID per call>`. A retry with the same key replays the stored result without a new charge.
**Response:** the provider response after any endpoint-specific normalization. `X-Locus-Credits-Charged` carries the charge and `X-Locus-Credits-Balance` the remaining balance. Insufficient credits return `402` before the provider is called.
**Pricing:** estimated costs below are USD. Locus debits the credit equivalent at your workspace rate.

Full call contract: https://docs.paywithlocus.com/api-reference/introduction

> Using a Pay With Locus wallet key (`claw_` prefix)? Wallet routes are documented separately: https://docs.paywithlocus.com/wrapped-apis/for-agents

## Endpoints

### Get all articulations

Get Computer Science B.S. articulation data for multiple California Community Colleges transferring to UC Davis. Processes CCCs in alphabetical order. The offset selects the start position and batch_size controls how many to process. Each CCC requires multiple upstream API calls (~6s each); use a batch_size of 1-2 per call to avoid timeouts. Returns summary statistics and an array of articulation results.

**Estimated cost:** Metered

| Field | Type | Required | Description |
|-------|------|----------|-------------|
| `academic_year_id` | integer | No | Academic year ID (76=2025-2026, 75=2024-2025, 74=2023-2024) |
| `batch_size` | integer | No | Max number of CCCs to process (0 = all). Recommended: 1-2 per call to avoid timeouts. |
| `offset` | integer | No | Start index in the alphabetically sorted CCC list (0-based) |

```bash
curl -X POST https://api.paywithlocus.com/api/wrapped/credits/assist/get-all-articulations \
  -H "Authorization: Bearer $LOCUS_CREDITS_SECRET_KEY" \
  -H "Idempotency-Key: $(uuidgen)" \
  -H "Content-Type: application/json" \
  -d '{"academic_year_id":"<integer>","batch_size":"<integer>","offset":"<integer>"}'
```

### Get single articulation

Get Computer Science B.S. course articulation data for a single California Community College transferring to UC Davis. Returns the receiving institution's course requirements and the equivalent CCC courses that satisfy them. Either ccc_name or ccc_id must be provided. Course mappings are grouped by section (e.g. MATHEMATICS, COMPUTER SCIENCE ENGINEERING).

**Estimated cost:** Metered

| Field | Type | Required | Description |
|-------|------|----------|-------------|
| `academic_year_id` | integer | No | Academic year ID (76=2025-2026, 75=2024-2025, 74=2023-2024) |
| `ccc_id` | integer | No | ASSIST.org institution ID of the CCC (from list_cccs endpoint). Either ccc_name or ccc_id is required. |
| `ccc_name` | string | No | Partial or full name of the CCC (case-insensitive substring match). Either ccc_name or ccc_id is required. |

```bash
curl -X POST https://api.paywithlocus.com/api/wrapped/credits/assist/get-single-articulation \
  -H "Authorization: Bearer $LOCUS_CREDITS_SECRET_KEY" \
  -H "Idempotency-Key: $(uuidgen)" \
  -H "Content-Type: application/json" \
  -d '{"academic_year_id":"<integer>","ccc_id":"<integer>","ccc_name":"<string>"}'
```

### List cccs

List all California Community Colleges with their ASSIST.org institution IDs and names. Returns the full set of 116 CCCs. Each entry provides the id needed for get_single_articulation and the name for substring search.

**Estimated cost:** Metered

_No parameters required._

```bash
curl -X POST https://api.paywithlocus.com/api/wrapped/credits/assist/list-cccs \
  -H "Authorization: Bearer $LOCUS_CREDITS_SECRET_KEY" \
  -H "Idempotency-Key: $(uuidgen)" \
  -H "Content-Type: application/json" \
  -d '{}'
```
