set up agent payments with x402 or MPP
let your AI agent pay per launch with x402 crypto or MPP Stripe - no account, no API key, no human in the loop.
steps
understand the two protocols
x402 uses USDC on Base (crypto). MPP uses Stripe (card). both cost $0.50/launch after 5 free launches/month. no account or signup needed for either.
choose your protocol
x402 if your agent already has a crypto wallet. MPP if you prefer standard card payments. both produce the same result.
most agents default to MPP since it doesn't require managing crypto keys.
configure x402 payments
agent needs a wallet with USDC on Base. include the payment proof in the X-PAYMENT header. the x402 facilitator handles verification. see https://www.x402.org for the spec.
testnet available for development.
configure MPP payments
agent pays with a standard card via Stripe's machine payment protocol. include the MPP payment token in the request. see https://www.mppx.dev for the spec.
make your first paid launch
POST to api.dropspace.dev/launches with the payment header. the response includes post URLs for each platform. first 5 launches/month are free per identity (wallet address or card).
use dropspace_platforms to post to official accounts - no OAuth setup needed.
handle errors and monitor usage
402 means payment required (free tier exhausted). 400 means invalid payment proof. track usage via the response headers.
the /usage endpoint shows remaining free launches.
protocol comparison
x402 is crypto-native - no intermediary, USDC on Base. MPP is card-native - Stripe-backed, any card. both are open protocols designed for machine-to-machine payments. pick whichever fits your agent's existing payment infrastructure.
