Fields in this listing; additional options and input encoding can vary by provider.
| Parameter | Location | Type | Required | Description |
|---|---|---|---|---|
articleNumber | JSON request bodybody | string | Yes | Current article number, e.g. `3` or `第三条` (Article 3). Write Article 17-1 as 17.1 or `第十七条之一`. minLength: 1 · maxLength: 40 |
asOf | JSON request bodybody | string | null | No | Locate a specific version; if omitted, return the complete timeline. Accepts a date YYYY-MM-DD (locates by effective date: which version was in force on that date), a version label (e.g. `2018修正`, amended in 2018, as returned by list_law_versions; for the Criminal Law and similar statutes, use `2023修正`, not `刑法修正案（十一）`, Amendment XI to the Criminal Law), or current (the current version). Date-based resolution causes an error if the chain contains versions with unknown effective dates; use a version label instead. |
includeUnchanged | JSON request bodybody | boolean | No | Whether to retain versions whose original texts are verified as character-for-character identical to the previous version. Default true: lawyers often use the fact that an article was unchanged in a particular amendment or revision as counterevidence. false filters out only versions with textComparison=confirmedIdentical; all unverifiable versions are retained, because treating unknown as unchanged and filtering it out would cause greater distortion. counts always counts all recorded snapshots and is unaffected by this parameter. |
lawTitle | JSON request bodybody | string | Yes | Statute name. Full or abbreviated names are accepted, e.g. `公司法` (Company Law), `民法典` (Civil Code), or `上海市生活垃圾管理条例` (Shanghai Municipal Regulations on Domestic Waste Management). Version hints such as `新公司法` (new Company Law), `2023公司法` (2023 Company Law), or `公司法 2023修订` (Company Law, revised in 2023) are also accepted. For long names of judicial interpretations, meeting minutes, and similar documents, supply as much of the full name as possible. Maximum 200 characters. minLength: 1 · maxLength: 200 |
Required markers inside a nested object or variant apply when that object or variant is used.

Common questions
Do I need a separate key for every provider?
Use your OpenAny API key for standard API access. Read it from OPENANY_API_KEY in your environment and keep it out of prompts, source code and logs.
Are these providers interchangeable?
No. Each offering has its own inputs, pricing and response contract. Selecting a catalog offering does not establish automatic routing or fallback. Confirm the service contract before calling.
How is this API billed?
API-key calls use your shared balance at the selected implementation's published rate. Check the billing unit and request-specific pricing rules before making a paid call. Recorded usage determines the final charge under that contract.
Where do the price and contract come from?
The selected implementation publishes its provider, request contract, revision and billing rules through OpenAny's public API catalog. A revision number identifies a contract version, not a price update date. A price update timestamp is not supplied; do not treat a page date as one.
How do OpenAny Balance and x402 differ?
OpenAny Balance uses an API key and one shared balance. Card, USDC and x402 top-ups, card auto top-up and USDC subscriptions fund that balance; available routes appear on the Credits page. Direct x402 is a separate pay-per-request flow, available only on listings that show it and requiring an authorized payment client.
Does Playground send a paid request?
Yes. After you sign in, Run sends a real API request using an active OpenAny API key. Charges follow the published API contract and use your shared balance. Selecting an implementation, editing inputs and viewing sample responses do not send requests.
