# List catalog price versions

GET https://api.runledger.co/v1/catalog/prices

The versioned prices of catalog models, newest first, including versions that are scheduled to take effect later. Use `changed_since` to read what changed since you last looked. Each version names its source and the date it takes effect. Needs `config:read`.

Reference: https://docs.runledger.co/api-reference/catalog/prices/list

## Authentication

- `Authorization` header (bearer token, required) — A secret key (`rl_sk_test_...`, `rl_sk_live_...`) or a restricted key with limited scopes (`rl_rk_test_...`, `rl_rk_live_...`). A restricted key can carry `agent: true` and an `expires_at`, and is what a coding agent should hold. Keys end in a checksum so secret scanners can recognize them. People create, roll and revoke keys in the dashboard; `GET /v1/api_keys` lists them, masked.

## Request

### Query parameters

- `catalog_model` (string, optional) — Only versions of this catalog model (`catm_...`).
- `provider` (string, optional) — Only versions for models of this provider key.
- `status` (enum, optional) — Only versions with this status.
  - Allowed values: `scheduled`, `active`, `superseded`
- `changed_since` (datetime, optional) — Only versions Runledger published at or after this time.
- `limit` (integer, optional, default: 20) — Maximum number of objects to return, from 1 to 100.
- `cursor` (string, optional) — The `next_cursor` from the previous page.

## Response

### 200

A page of catalog price versions.

- `object` ("list", required)
- `data` (list of CatalogPrice, required)
- `has_more` (boolean, required)
- `next_cursor` (string, optional)

## Errors

### 400 Bad Request Error

The request was malformed or a parameter was invalid. A configuration that fails validation, such as two equally specific overrides with overlapping dates, returns `config_invalid`.

- `type` (string, required) — A URI for the error type. It links to the error codes table in the docs, where each `code` is listed with its cause. Branch on `code`, not on `type`.
- `title` (string, required) — A short summary of the error type.
- `status` (integer, required) — The HTTP status code.
- `code` (enum, required) — A stable, machine-readable error code. New codes may be added.
  - Allowed values: `invalid_request`, `parameter_missing`, `parameter_invalid`, `parameter_unknown`, `authentication_failed`, `permission_denied`, `insufficient_scope`, `proposal_required`, `config_invalid`, `livemode_mismatch`, `resource_not_found`, `resource_already_exists`, `idempotency_key_in_use`, `idempotency_key_reused`, `invalid_state`, `outcome_charge_locked`, `hold_not_active`, `insufficient_balance`, `credit_limit_exceeded`, `plan_locked`, `test_clock_advancing`, `provider_error`, `rate_limited`, `api_error`, `service_unavailable`
- `request_id` (string, required) — The ID of the request. Quote it to support, or look it up in request logs.
- `retryable` (boolean, required) — Whether sending the same request again, with the same idempotency key, may succeed.
- `detail` (string, optional) — An explanation of this occurrence. For people; don't parse it.
- `param` (string, optional) — The request parameter at fault, as a dotted path.
- `required_scope` (string, optional) — The scope the call needed, on `insufficient_scope`. Ask a person to widen the key, or reconnect with it.
- `errors` (list of ConfigIssue, optional) — Only with `config_invalid`: each problem the configuration document has, with the path of the part at fault, so an agent can fix the document without a second call.
- `blocked_by` (list of ErrorResponseBlockedByItems, optional) — On an `invalid_state` that names the objects in the way, the objects that must change first. Removing a payment provider lists every routing rule that uses it (`object: routing_rule`) and every customer whose own `payment_provider` names it (`object: customer`), in one list.

## Types

### CatalogPrice

One version of a catalog model's rates. A published version never changes: a price change, or a correction, is a new version with its own `effective_from`. A corrected price takes effect from the date it is published, not from an earlier date.

- `id` (string, required)
- `object` ("catalog_price", required)
- `catalog_model` (string, required) — The catalog model ID.
- `version` (integer, required) — 1 for the first version of a catalog model's prices, then one more for each change.
- `status` (enum, required) — `scheduled`: takes effect at `effective_from`. `active`: in force. `superseded`: replaced by a later version.
  - Allowed values: `scheduled`, `active`, `superseded`
- `currency` (string, required) — The currency the provider quotes. Runledger doesn't convert between currencies.
- `rates` (list of CostRate, required)
- `effective_from` (datetime, required) — When these rates start to apply. It is never earlier than the day the version is published, and that includes a correction. Costs dated before it keep the earlier version, and recorded costs are never repriced.
- `as_of` (date, required) — The date Runledger read these rates from the source.
- `source_url` (string, required) — Where the rates were read: the provider's pricing page or its change notice.
- `published_at` (datetime, required) — When Runledger published this version, which can be before it takes effect. The freshness target is to publish a provider's price change within 1 business day of the provider publishing it. A business day is Monday to Friday in Sydney time, with no public holiday calendar.
- `last_verified_at` (datetime, required) — When Runledger last checked this version against its source.
- `effective_to` (datetime, optional) — When a later version replaced this one. Left out while it is in force.
- `source_reference` (string, optional) — A note on the source, such as the page title or the notice date.
- `changes` (list of ConfigChange, optional) — What differs from the version before, rate by rate.

### ConfigIssue

A problem or warning about a part of a configuration document.

- `code` (string, required) — A stable code. New codes may be added.
- `message` (string, required)
- `path` (string, optional) — Where in the document, as a dotted path.

### ErrorResponseBlockedByItems

- `object` (enum, required) — The kind of object in the way: a routing rule, or a customer with a `payment_provider` override.
  - Allowed values: `routing_rule`, `customer`
- `id` (string, required) — The object's ID, `rr_...` for a routing rule and `cus_...` for a customer.

### CostRate

The price of one unit, for the usage lines whose dimensions match. A rate with fewer dimensions matches more lines, and the most specific matching rate wins. Send `unit_amount_decimal` or `tiers`.

- `unit` (string, required)
- `per` (string, optional, default: 1) — How many units `unit_amount_decimal` covers, as a decimal string. Use `"1000000"` for a price per million tokens.
- `unit_amount_decimal` (string, optional) — Minor units of the rate card's currency for `per` units, as a decimal string.
- `dimensions` (map from string to string, optional) — The dimension values this rate is for. Leave a dimension out to match any value.
- `tier_mode` (enum, optional, default: graduated) — With `tiers`. `graduated`: each band's price applies to the quantity inside that band. `volume`: the band the whole quantity falls in prices all of it, as when a long prompt is priced higher in full.
  - Allowed values: `graduated`, `volume`
- `tiers` (list of RateTier, optional)

### ConfigChange

One field that changes, with its value before and after. A removed object or field has `before` and no `after`: a replace (`PUT /v1/config`) lists each removal this way, before anything is applied.

- `path` (string, required)
- `before` (any, optional) — The current value. Left out when the field is new.
- `after` (any, optional) — The new value. Left out when the field is removed.

### RateTier

One band of a quantity. The last band leaves out `up_to`.

- `unit_amount_decimal` (string, required) — Minor units per unit of the band, as a decimal string.
- `up_to` (string, optional) — The quantity this band runs up to, as a decimal string.
