Every issued x402 signature has a hold: `outstanding` while it is settleable, `settled` once the transfer is seen on-chain, `released` if its window closed unused. Outstanding and settled holds both count against the mandate's budget; a released one returns it. This is the only record of x402 spend - an x402 authorization moves money without a Dakota-initiated transaction, so it writes no transaction row. ## OpenAPI ````yaml /openapi.yaml get /payment-agents/{payment_agent_id}/x402/holds 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. servers: - url: https://api.platform.dakota.xyz description: Production environment - url: https://api.platform.sandbox.dakota.xyz description: Sandbox — safe for testing with simulated data security: - ApiKeyAuth: [] tags: - name: Agentic Payments x-beta: true description: >- Beta — agent-driven payments: provision agents, draft and approve spending mandates, accept reviewed instructions, and manage scheduled payments. **Prerequisites:** Customer onboarded; signer groups attached for recognition. **Related:** Wallets, Signer Groups, Transactions - name: Mandates x-beta: true description: >- Beta — spending mandates: signed, signer-bound authorizations governing what may be spent, approved or cancelled by a second recognized signer (§8 — the dual-control rule that every mandate mutation must be signed by a recognized signer OTHER than the bound one).

These operations are served under `/capabilities/*` - `GET /capabilities/countries` and `GET /capabilities/networks`. The tag name does not appear in the request paths. **Prerequisites:** Valid authentication headers. **Related:** Accounts, Transactions - name: Sandbox description: >- Trigger sandbox-only simulation endpoints for safe end-to-end integration testing with synthetic data. The sandbox host (`https://api.platform.sandbox.dakota.xyz`) also accepts a family of `X-Sandbox-*` request headers on most write endpoints (`Customers`, `Accounts`, `Transactions`, simulate endpoints) that let integrators drive deterministic failure modes — pick a preset via `X-Sandbox-Scenario`, or compose a custom one with `X-Sandbox-Error-Step`/`X-Sandbox-Error-Status`/`X-Sandbox-Error-Message`. `X-Sandbox-Instant-Completion` collapses async flows to a single synchronous step, and `X-Sandbox-Skip-Auto-Approval` keeps newly created KYB applications in `pending` for manual-review testing. All `X-Sandbox-*` headers are ignored in production. **Prerequisites:** Sandbox environment and test customer data. **Related:** Customers, Accounts, Transactions, Onboarding - name: Legal description: |- The legal documents customers accept — terms of service, privacy policy, e-sign notice, and partner agreements. Dakota publishes these here, and this is the authoritative source: the hosted onboarding flow, the dakota.xyz website, and your own integration all read the same revisions.

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.
