Loyal Spark Loyalty Protocol

Get info about Loyal Spark protocol on Base L2

Get authenticated agent's profile

Workflow planner: field catalog, required parameters, next_actions, and non-binding examples. External agents must choose their own name, symbol, and economics.

Explain the next merchant action: current_step, required fields, and ordered next_actions (you provide all parameter values)

List loyalty programs owned by the agent's merchant

Get factory calldata to deploy a new loyalty token on Base. Defaults to B20 (Base native ERC-20 superset, single tx, active immediately). Pass token_standard='erc20' for the legacy factory. For B20, MINT_ROLE is granted atomically to the merchant admin AND to the agent's CDP wallet (or explicit extra_minters) so autonomous agents can mint with no follow-up transaction.

Register a deployed token as a loyalty program in the database. B20 tokens are registered as active; legacy ERC-20 as inactive (activate next).

For legacy ERC-20 programs: returns unpauseUtility + enableMinting calldata. For B20 programs: no-op (already active).

Update program status in database after onchain activation/pause

Update default cashback_rate and/or points_per_dollar for a program (same as merchant dashboard sliders)

List rewards for a loyalty program by token_address. Includes redemption metrics (total vouchers issued, redeemed, and last-30-day counts) for each reward.

Create a new reward redeemable with loyalty tokens

Record mint intent and get a fee-first `calls[]` bundle: protocol fee mint FIRST, then the recipient mint. The protocol fee is charged in the merchant's own loyalty tokens (not USDC). Submit both calls in order (atomically via EIP-5792 send_calls if your wallet supports it), then call confirm_mint_fee (or POST /agent-api/mint/confirm) with the fee tx hash. Unconfirmed fee obligations block future mints.

Get calldata to transfer loyalty tokens between wallets

Calculate and mint loyalty tokens based on purchase amount and program's cashback rate. Returns a fee-first `calls[]` bundle (protocol fee mint first, then the customer mint) — submit in order, atomically via EIP-5792 if supported, then call confirm_mint_fee (or POST /agent-api/mint/confirm). Unconfirmed fee obligations block future mints.

Confirm that the protocol fee transaction for a previous mint/earn was broadcast on Base. Verifies the fee mint on-chain and clears the obligation. Unconfirmed fee obligations block future mints.

Get loyalty token balance and tier info for a customer

Get analytics for your loyalty programs

List active token trading offers on the marketplace

Redeem a reward by providing a verified token transfer transaction hash. Creates a voucher for the customer.

Mark a voucher as used (redeemed by customer at merchant). Merchant-only operation.

Check voucher status by code or ID. Public endpoint — no API key or authentication required.

Get global platform statistics across all merchants. Admin-only: requires agent owned by an admin wallet.

Cancel marketplace offers that have been active for more than N days with no completions. Admin-only action tool.

Create a personalized offer for a specific customer. Use when analytics reveal engagement patterns (e.g., inactive customers, high-value segments).

Activate or deactivate a reward in the catalog. Use to manage reward availability based on analytics.

Send a report to the developer/owner. Use this to submit SEO audits, growth ideas, data reports, anomalies, recommendations, or weekly summaries. The report will appear in the merchant's Agent Reports dashboard.

List your previously submitted reports. Allows reviewing past reports, checking status (new/reviewed/done), and identifying what still needs attention.

Update report status to 'reviewed' or 'done'. Use 'done' when the action items have been completed. Use 'reviewed' to acknowledge a report.

Delete a report that is no longer relevant. Use to clean up outdated or irrelevant reports.

Export customer data for a specific loyalty program. Returns wallet addresses, voucher stats, balances, and tier info. Use for analytics, segmentation, and personalized offers.

Create a gift / welcome certificate (UDS-style) with a unique 6-character redemption code (LOYAL-XXXXXX). Customer redeems via QR or by entering the code; merchant then mints tokens on-chain. Use for welcome bonuses, promo campaigns, partnership gifts.

List gift certificates issued by the agent's merchant (with status and redemption info).

Revoke an active gift certificate (status active → revoked). Only the issuing merchant can revoke. Already-redeemed/minted certificates cannot be revoked.

After the merchant submits the on-chain mint transaction for a claimed gift certificate, call this to mark it as minted (status pending_mint → redeemed) and store the mint tx hash.

Discover third-party x402-paid resources published in Coinbase CDP's Bazaar (docs, data feeds, AI inference, etc). Read-only. Filter by free-text q and/or network (e.g. 'base').

Discover third-party MCP servers published in Coinbase CDP's Bazaar. Read-only. Filter by free-text q and/or network.

GET a candidate x402 URL and, if it responds HTTP 402, return the parsed payment requirements (accepts[]) so the caller can decide whether to pay. HTTPS only. No signing performed.

Pay and call any x402-paid HTTPS endpoint using the merchant agent's CDP MPC wallet (EIP-3009 exact scheme on Base USDC). Probes the URL for HTTP 402, picks a compatible requirement, signs TransferWithAuthorization via CDP, retries with X-PAYMENT header, and returns the paid response. Requires scope 'mint' and a pre-created CDP wallet. Safety cap: max_usdc (default 0.25, hard limit 10).
