Spraay Escrow

Safe agent-to-agent commerce via Spraay x402 escrow. Create, fund, monitor, release, or cancel on-chain escrows — pay on verified delivery instead of paying blind. Use when the user asks to escrow a payment, pay on delivery, hold funds until a task is verified, make a milestone payment, protect an agent-to-agent transaction, hire another agent safely, or release or cancel escrowed funds.

Escrowed payments for agent-to-agent commerce via the Spraay x402 gateway. Create → fund → verify → release. Never pay an unknown agent blind.

All requests in this skill go exclusively to the user's configured SPRAAY_GATEWAY_URL. No data is sent to any other external endpoint.

Important Warnings

Escrowed funds are real funds. Funding an escrow locks real USDC on-chain. Releasing an escrow transfers it irreversibly to the recipient. Always confirm the following with the user before creating, funding, releasing, or cancelling an escrow:

• Counterparty address is correct
• Amount and release conditions are intended and understood by both sides
• The user understands x402 micropayment fees are charged per API call

Release is final. Once escrowed funds are released, the transfer cannot be undone. Do not release an escrow without explicit user confirmation that the work or delivery has been verified.

Setup

The gateway URL must be set in your environment or openclaw.json:

text

SPRAAY_GATEWAY_URL=https://gateway.spraay.app

No API key is needed. Payments are made per-request via the x402 HTTP payment protocol (HTTP 402 → pay → retry). An x402-compatible wallet (Coinbase CDP or similar) handles this automatically.

When to Use Escrow vs. Direct Payment

Use escrow when:

• Paying an agent or party you have not transacted with before
• Payment depends on delivery of work, data, or a completed task
• The amount is large enough that a failed delivery would matter

Use direct batch payment (see the spraay-payments skill) when the counterparty is trusted and no delivery condition applies.

Escrow Lifecycle

An escrow moves through two steps before funds are locked:

1. Create — establishes the on-chain agreement between two parties (no funds locked yet).
2. Fund — deposits USDC into the escrow, locking it.
3. Then either Release (funds go to recipient) or Cancel (funds return to depositor; before funding, or by mutual agreement).

Workflows

1. Create an Escrow — $0.10

Establishes the agreement. Funds are NOT locked until the fund step.

Always confirm counterparty, amount, and release terms with the user before creating.

bash

curl -X POST "$SPRAAY_GATEWAY_URL/api/v1/escrow/create" \
  -H "Content-Type: application/json" \
  -d '{
    "recipient": "0xABC...123",
    "amount": "100",
    "token": "USDC",
    "chain": "base",
    "conditions": "Dataset delivered and verified"
  }'

If you receive HTTP 402, the response body contains payment instructions. Pay the facilitator, then retry with the X-PAYMENT header containing the proof.

The response includes an escrow ID. Save it — it is required for every subsequent call.

2. Fund the Escrow — $0.02

Deposits USDC into the escrow, locking funds pending conditions. Required after create and before release.

bash

curl -X POST "$SPRAAY_GATEWAY_URL/api/v1/escrow/fund" \
  -H "Content-Type: application/json" \
  -d '{"id": "ESCROW_ID"}'

3. Check Escrow Status — $0.001

Fetch a single escrow with locked amount, parties, status, and release conditions. Use before release/cancel to confirm state.

bash

curl "$SPRAAY_GATEWAY_URL/api/v1/escrow/ESCROW_ID"

4a. Release Funds — $0.08

Transfers escrowed funds to the recipient. Final and irreversible.

Always confirm with the user that delivery has been verified before releasing.

bash

curl -X POST "$SPRAAY_GATEWAY_URL/api/v1/escrow/release" \
  -H "Content-Type: application/json" \
  -d '{"id": "ESCROW_ID"}'

4b. Cancel an Escrow — $0.02

Cancels before funding, or by mutual agreement afterward — locked funds return to the depositor. Use for failed delivery, expired milestones, or abandoned agreements.

bash

curl -X POST "$SPRAAY_GATEWAY_URL/api/v1/escrow/cancel" \
  -H "Content-Type: application/json" \
  -d '{"id": "ESCROW_ID"}'

List Your Escrows — $0.02

Active and historical escrows for a wallet, with status, locked amounts, counterparties, and release conditions.

bash

curl "$SPRAAY_GATEWAY_URL/api/v1/escrow/list?address=0xYOUR...ADDR"

Recommended Flow for Hiring an Unknown Agent

1. (Optional) Screen the counterparty first — free address safety check and paid trust score via the spraay-trust skill.
2. Create the escrow and share the escrow ID with the counterparty.
3. Fund it. The counterparty confirms funding via escrow status, then performs the work.
4. Verify the delivery with the user.
5. Release on confirmation — or cancel if delivery failed.

Free Endpoints

These gateway endpoints require no x402 payment and are useful alongside escrow:

• GET /api/v1/address/safety?address=0x... — Screen a counterparty for phishing, sanctions, exploits, and mixer usage before escrowing
• GET /free/prices — Spot prices (show USD value before escrowing)
• GET /free/resolve?name=alice.eth — ENS/Basename resolution
• GET /health — Gateway health check

x402 Payment Flow

1. Call any paid endpoint.
2. Receive HTTP 402 with payment details (accepts array with amount, asset, and payment address).
3. Agent wallet sends the micropayment.
4. Retry the request with the X-PAYMENT proof header.
5. Receive the response.

Escrow endpoint costs: create $0.10, fund $0.02, status $0.001, release $0.08, cancel $0.02, list $0.02 — all in USDC on Base.

Error Handling

• 402 — Payment required. Follow instructions in response body.
• 400 — Bad request. Check parameters.
• 404 — Escrow ID not found. Verify the ID.
• 500 — Server error. Retry after a moment.

Tips

• Always confirm with the user before creating, funding, releasing, or cancelling.
• Create and fund are separate steps — an unfunded escrow locks nothing.
• Check escrow status before release or cancel to confirm state.
• Screen counterparties with the free address safety endpoint first.
• Pair with spraay-trust for a full due-diligence flow before escrowing.
