# Create an x402 spend mandate (BETA)

> > **Beta** — early access.

Creates the standing allowance an agent pays x402-metered resources under. Unlike a payment mandate this authorizes a BUDGET rather than a payee: x402 payees are discovered at request time from a seller's 402 response, so the controls are a per-call ceiling plus a rolling aggregate across every payee. Amounts are atomic units of the asset (USDC has 6 decimals, so "100000" is $0.10).




## OpenAPI

````yaml /openapi.yaml post /payment-agents/{payment_agent_id}/x402/mandates
openapi: 3.0.3
info:
  title: Dakota Platform API
  version: 1.0.0
  description: >-
    Combined API specification for Dakota Platform services:

    - Issuance API: Asset minting and burning operations

    - Onboarding API: Know Your Business/Customer verification

    - On/Off Ramp API: Managing on-ramp and off-ramp accounts

    - Recipients API: Managing destinations for KYB'd entities

    - Transactions API: Viewing transaction history across platform operations


    ## Authentication and API Headers


    All API endpoints require the following headers:


    - `X-Idempotency-Key`: Required for all POST endpoints to ensure request
    idempotency

    - `x-api-key`: Required for authentication across all endpoints


    Note: On /applications endpoints you need a token for authentication instead
    of a x-api-key

    - `x-application-token`: Required for authentication on public /applications
    endpoints (alternative to `x-api-key` where documented)



    ## Rate Limits


    Requests are rate limited per API key. Every response includes the following
    headers:


    | Header | Description |

    | --- | --- |

    | `X-RateLimit-Limit` | Maximum requests allowed in the current one-minute
    window. |

    | `X-RateLimit-Remaining` | Requests remaining in the current window. |

    | `X-RateLimit-Reset` | Absolute Unix timestamp (seconds since epoch) when
    the current rate-limit window resets. |


    When a request is throttled (`429`), responses also include `Retry-After`
    with seconds to wait before retrying.

            customer, present when one exists for this error. `detail` names
            request fields and actions so a machine caller (such as a payment
            agent drafting proposals) can self-correct; `user_message` says the
            same thing without API vocabulary. Clients that relay errors into a
            human surface (chat, email, UI) should show `user_message` when
            present and fall back to `detail`.
          example: >-
            ACH payments pay out USD, so a USDC payout isn't possible on this
            rail. Change the payout currency to USD and try again.

        object to leave the budget as the only control.

        `mode` is required when the object is present, and the list must match
        it: `address_allowlist` needs `addresses` and reads no domains,
        `domain_allowlist` needs `domains` and reads no addresses, and
        `any_screened` enforces neither, so it carries no list. A policy that
        breaks those rules is refused with a 400 rather than stored as a
        restriction nothing applies.

        `any_screened` accepts any payee that passes address screening.
        `address_allowlist` pins the payee address itself. `domain_allowlist`
        pins the RESOURCE host the caller names when it asks for a signature -
        the readable form, since an operator approves "any metered API under
        this vendor's domain" rather than a hex address. Note that it bounds the
        resource, not the payee: a seller who prices one resource can be paid
        for it whatever address it nominates.
