From the repository
Register at loyalspark.online/merchant in the AI Agents tab, obtain an API key with the lsk_ prefix, and include it in the x-api-key header. Then invoke the available tools such as get_platform_info, list_loyalty_programs, create_reward, mint_loyalty_tokens, and list_marketplace_offers.
get_platform_info
Get info about Loyal Spark protocol on Base L2
get_my_profile
Get authenticated agent's profile
generate_program_defaults
Workflow planner: field catalog, required parameters, next_actions, and non-binding examples. External agents must choose their own name, symbol, and economics.
get_program_workflow_status
Explain the next merchant action: current_step, required fields, and ordered next_actions (you provide all parameter values)
list_loyalty_programs
List loyalty programs owned by the agent's merchant
create_loyalty_program
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_loyalty_program
Register a deployed token as a loyalty program in the database. B20 tokens are registered as active; legacy ERC-20 as inactive (activate next).
activate_loyalty_program
For legacy ERC-20 programs: returns unpauseUtility + enableMinting calldata. For B20 programs: no-op (already active).
update_program_status
Update program status in database after onchain activation/pause
update_program_config
Update default cashback_rate and/or points_per_dollar for a program (same as merchant dashboard sliders)
list_rewards
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_reward
Create a new reward redeemable with loyalty tokens
mint_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.
transfer_loyalty_tokens
Get calldata to transfer loyalty tokens between wallets
earn_points
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_mint_fee
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_token_balance
Get loyalty token balance and tier info for a customer
get_program_analytics
Get analytics for your loyalty programs
list_marketplace_offers
List active token trading offers on the marketplace
redeem_reward
Redeem a reward by providing a verified token transfer transaction hash. Creates a voucher for the customer.
use_voucher
Mark a voucher as used (redeemed by customer at merchant). Merchant-only operation.
check_voucher_status
Check voucher status by code or ID. Public endpoint — no API key or authentication required.
get_platform_stats
Get global platform statistics across all merchants. Admin-only: requires agent owned by an admin wallet.
cancel_stale_offers
Cancel marketplace offers that have been active for more than N days with no completions. Admin-only action tool.
create_personalized_offer
Create a personalized offer for a specific customer. Use when analytics reveal engagement patterns (e.g., inactive customers, high-value segments).
update_reward_status
Activate or deactivate a reward in the catalog. Use to manage reward availability based on analytics.
send_report
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_my_reports
List your previously submitted reports. Allows reviewing past reports, checking status (new/reviewed/done), and identifying what still needs attention.
update_report_status
Update report status to 'reviewed' or 'done'. Use 'done' when the action items have been completed. Use 'reviewed' to acknowledge a report.
delete_report
Delete a report that is no longer relevant. Use to clean up outdated or irrelevant reports.
export_customers
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_gift_certificate
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
List gift certificates issued by the agent's merchant (with status and redemption info).
revoke_gift_certificate
Revoke an active gift certificate (status active → revoked). Only the issuing merchant can revoke. Already-redeemed/minted certificates cannot be revoked.
mark_gift_certificate_minted
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.
bazaar_discover_resources
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').
bazaar_discover_mcp_servers
Discover third-party MCP servers published in Coinbase CDP's Bazaar. Read-only. Filter by free-text q and/or network.
bazaar_probe_x402
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.
bazaar_pay_and_call
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).
