# List opportunities
> Read the opportunity library: publisher surfaces where a link or citation could be earned, one record per surface with its evidence, gate verdicts, verification state, provenance, rights and dates.
`list_opportunities`
Read the opportunity library: publisher surfaces where a link or citation could be earned, one record per surface with its evidence, gate verdicts, verification state, provenance, rights and dates. Filter by niche, opportunity type, status, route state, freshness, source class and updated-since; page with the returned cursor. Ordered by update time, never by authority. Every answer carries the coverage block for the niches read; a surface absent from the result was not read and is not known to lack an opportunity. No score, no contact data, no fetch.
Available in the deployed MCP and HTTP bundle. Confirm access and inputs with your connected catalog. Workspace scopes and enabled providers still apply.

## Example request
Connect through [MCP](/guides/connect-mcp), [CLI](/guides/connect-cli), or [HTTP](/guides/connect-http). Replace example identifiers with records from your workspace.
```json MCP theme={null}

"params": {
"name": "list_opportunities",
"arguments": {

}
```
```bash CLI theme={null}

```
```bash HTTP theme={null}

```
## Returned result
Illustrative data validated against the documented response schema. IDs and dates are examples, not a live account capture. MCP returns this data in `structuredContent` and in a text content block; generic HTTP and CLI return the JSON result directly.

## Input fields
Omit optional fields when you do not want to supply them. Null is accepted only where listed. Unknown input properties are rejected.
| Field | Type | Presence | Meaning and constraints |
| ----------------- | ------- | -------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `niche` | string | Optional | Niche id from the library niche table, such as us-probate. Omit to read every niche. maxLength: 64; pattern: "^\[a-z0-9-]+\$" |
| `opportunityType` | string | Optional | How a link would be earned on the surface: one of the six library opportunity types. values: "directory", "resource\_page", "listicle\_or\_review", "guest\_post\_program", "link\_insertion", "ai\_citation\_source" |
| `status` | string | Optional | Record status: held, published or withdrawn. Records are never deleted, so withdrawn records remain readable with their reason. values: "held", "published", "withdrawn" |
| `routeState` | string | Optional | Route verification state: verified (route page read and states the route), partial (renders client-side) or unverified (could not be read). values: "verified", "partial", "unverified" |
| `freshness` | string | Optional | Age of the last verification against the fixed 90-day window: fresh (under 60 days), aging (60 to 90 days) or stale (over 90 days or never verified). Computed at read time. values: "fresh", "aging", "stale" |
| `sourceClass` | string | Optional | Provenance source class, which decides redistribution rights per class, never per row. values: "owned\_corpus", "directory\_inventory", "cc\_host\_graph\_seed", "consented\_project\_lane", "owned\_submission" |
| `updatedSince` | string | Optional | ISO 8601 timestamp; only records whose dates.updated\_at is at or after this instant are returned. format: "date-time"; pattern: "^(?:(?:\d\d\[2468]\[048]\|\d\d\[13579]\[26]\|\d\d0\[48]\|\[02468]\[048]00\|\[13579]\[26]00)-02-29\|\d\{4}-(?:(?:0\[13578]\|1\[02])-(?:0\[1-9]\|\[12]\d\|3\[01])\|(?:0\[469]\|11)-(?:0\[1-9]\|\[12]\d\|30)\|(?:02)-(?:0\[1-9]\|1\d\|2\[0-8])))T(?:(?:\[01]\d\|2\[0-3]):\[0-5]\d:\[0-5]\d(?:\\.\d+)?(?:Z\|([+-](?:\[01]\d\|2\[0-3]):\[0-5]\d)))\$" |
| `cursor` | string | Optional | Opaque continuation returned by this same listing with the same filters; omit for the first page. minLength: 1; maxLength: 1024 |
| `limit` | integer | Optional | Maximum records in this page, 1 to 100; defaults to 100. minimum: 1; maximum: 100; default: 100 |
### Validation and omitted values
Omit cursor for the first page. Keep continuation cursors opaque and use them only with the same filters; a cursor from a different filter set is refused with INVALID\_CURSOR.
Pages are ordered by dates.updated\_at descending, then record\_id. Nothing in the library is ordered by authority, traffic or rel tokens, and no record carries a score.
Every answer carries the coverage block for the niches read and absence\_claim not\_supported. A record missing from the result was not read; it is never evidence that a surface has no opportunity.
freshness is computed at read time from verification.last\_verified\_at against the fixed 90-day window (aging from day 60) and is not stored on the record.
Omitted filters apply no restriction. Records are product data shared across workspaces; nothing here names a customer, a customer's target or a contact address.
### Defaults when omitted
| Field | Default |
| ------- | ------- |
| `limit` | `100` |
## Output fields
Fields inside optional or nullable parents apply only when that parent exists. [Common schema conventions](/reference/schemas) explain evidence states, empty lists and extensions.
* **`schema_version`** (number, required): must equal 1
* **`read_at`** (string, required): UTC timestamp the read used for freshness.
* **`freshness_basis`** (object, required).
* **`absence_claim`** (string, required): not\_supported: missing dataset rows cannot prove link absence. must equal "not\_supported"
* **`whole_web_coverage`** (boolean, required): False: these results do not measure the whole web. must equal false
* **`absence_note`** (string, required): Plain statement that a surface missing from this result was not read; it is never evidence that no opportunity exists.
* **`coverage`** (array, required): Dataset scope and completeness, including limits on what these results establish.
* **`filters`** (object, required).
* **`ordering`** (string, required): How the page is ordered: by update time then record id, never by authority, traffic or rel tokens.
* **`limit`** (number, required).
* **`items`** (array, required): Records in this bounded page.
* **`has_more`** (boolean, required): True when another page is available.
* **`next_cursor`** (string / null, required): Opaque continuation for the same listing; null means no further page.

## Errors and retries
The command is annotated idempotent. Reuse an accepted idempotency key when the input provides one; changing the payload under a reused key can conflict.
See [error recovery](/reference/errors) for status, scope, cooldown, cursor and retry handling. Unknown observations are result data and do not establish loss.
## HTTP resource routes
These existing resource routes share the operation’s domain behavior. Their parameter placement, status and response envelope can differ from generic invocation. See [HTTP route details](/reference/http/routes).
| Method and route | Success | Details |
