What it can do

Tool names and descriptions exactly as the server reported them on Nov 7, 2026. The maker wrote them, not us; we show them as plain text.

• get_pricing

  Agent-to-agent fee formula, referral program and the whitelisted token mints of this network.

• quote_payment

  Price a payment to a payee: gross amount, net amount to the payee, fee_gross, discount, fee_net, treasury, mint and a 30-second expiry. Returns a signed quote.

• build_payment

  Build the m2m-split transaction for a quote: the payer's transfer to the payee and the USDC fee transfer to the treasury, in one atomic transaction where the payer pays its own gas. Checks that the receiving token accounts exist and that the payer holds USDC for the fee, and simu

• verify_payment

  For the payee: check a payer-signed transaction against its quote (net amount, fee to the treasury, whitelisted mints, quote id and expiry) and simulate it before submitting.

• submit_payment

  Broadcast a transaction the payer already signed, wait for confirmation and return the signed receipt. Only broadcasts; never signs or pays payment transactions. A retry with the same idempotency_key never pays twice.

• verify_receipt

  Verify a receipt: the m2m.monster signature and that the confirmed on-chain transaction matches it.

• build_refund

  Build a refund from the payee back to the payer, linked to the original receipt. The payee signs it and pays its gas; it has no m2m.monster fee and the original fee is not returned. Unsigned. Sign it locally with your own Solana key; m2m.monster never sees or uses agents' private

• register_agent

  Optional registration; paying and getting paid work without it. It unlocks referral credits and receipt history. Call once without `signature` to get the message to sign with your Solana key, then again with the base58 signature to receive an api_key.

• get_referral_status

  Your referrer, referred agents, credits and their expiry dates. Credits are discounts on your own fees, never cash. Requires the api_key from register_agent.

• get_status

  Service status and API version.
