# Update a payment rule
PATCH/zones/{zone\_id}/monetization/rules/{rule\_id}
Applies a partial update to a single Payment Required rule. Only the fields present in the request body are changed; omitted fields keep their current values. Returns the full resulting rule collection.
##### Security
API Token
The preferred authorization scheme for interacting with the Cloudflare API. Create a token.
**Example:**Authorization: Bearer Sn3lZJTBX6kkg7OdcBUAxOO963GEIyGQqnFTOFYY
API Email + API Key
The previous authorization scheme for interacting with the Cloudflare API, used in conjunction with a Global API key.
**Example:**X-Auth-Email: user@example.com
The previous authorization scheme for interacting with the Cloudflare API. When possible, use API tokens instead of Global API keys.
**Example:**X-Auth-Key: 144c9defac04969c7bfad8efaa8ea194

##### Body ParametersJSONExpand Collapse
address: optional string
0x-prefixed 20-byte hexadecimal Ethereum address. Mixed-case addresses must carry a valid EIP-55 checksum; all-lowercase or all-uppercase addresses are also accepted. The effective address must pass wallet screening whenever the rule is patched.

expression: optional string
Wirefilter expression identifying the requests that require payment. Forwarded verbatim to the Rulesets API, which validates its syntax.

price: optional string
Price in the smallest indivisible unit of the configured payment token, encoded as a decimal string. Must be a canonical decimal integer in \[1000, 100000000]: no leading zeros, and a bare JSON number is rejected. The price is required for the fixed-price schemes (“exact” and “upto”) and must be at least 1000, the smallest amount the payment facilitator can settle ($0.001 for a 6-decimal token such as USDC), and at most 100000000 ($100 for a 6-decimal token). When the scheme is “origin\_controlled” the origin server sets pricing dynamically and the rule carries no price: the field must be omitted — any provided value, including “0”, is rejected because it would not be enforced. Responses always encode this as a string and omit it for “origin\_controlled” rules; the pattern matches exactly the set of values the server accepts.

scheme: optional "exact"or "upto"or "origin\_controlled"
X402 payment scheme. “exact” requires the specified payment amount; “upto” permits a payment up to the specified amount; “origin\_controlled” lets the origin server set pricing dynamically, in which case the rule carries no price and the price field must be omitted.

result: MonetizationRuleCollection { rules }
The zone’s payment rules. Mirrors the shape of the ruleset submitted to the deploy endpoint, so the response can be read back as the desired state.
rules: array of MonetizationRule
The zone’s payment rules, in the order they are evaluated. Empty when the zone has no payment rules.
One of the following:
MonetizationRulesMonetizationRuleInputFixedPrice = MonetizationRuleInputFixedPrice { address, expression, price, 4 more }
Payment rule with a fixed price set at configuration time.
id: string
The server-assigned unique ID of the payment rule. Stable across full-ruleset replacements.

MonetizationRulesMonetizationRuleInputOriginControlled = MonetizationRuleInputOriginControlled { address, expression, scheme, 3 more }
Payment rule whose price the origin server sets dynamically. The rule carries no price and the price field must be omitted — any provided value, including “0”, is rejected because it would not be enforced.
