What we index
- x402 is an open standard built on the web's HTTP 402 "Payment Required" status code. A paid API answers a request with a price, and an agent pays per call in stablecoins (digital dollars such as USDC).
- MPP (Machine Payments Protocol), from Stripe and Tempo, lets agents pay for services per request and settles on the Tempo blockchain.
- A facilitator is the service that checks a signed payment and submits it to the blockchain for settlement.

Also this week in the AI economy
- Mastercard opened early access to Agent Pay for Machines (Oct 20). It builds on x402 and gives developers APIs, a toolkit and a sandbox, with Base among the settlement networks in early pilots. Mastercard
- Visa, BILL and Billtrust launched a live pilot of AI agents paying supplier invoices (Oct 20). Agents authenticate with Visa's Trusted Agent Protocol and pay already-approved B2B (business-to-business) invoices on card rails. Visa
- Stripe launched Treasury for agents (Oct 21). Startups can let agents check balances, pay invoices and move funds through Stripe's MCP (Model Context Protocol) server, and choose when money movement needs human approval. Stripe

Notes
- Indexed volume excludes self-transfers, router hops (intermediate contract legs of one payment), fee legs, payments where a facilitator is a party, and facilitator-to-facilitator payments.
- Solana and Base figures exclude all payments under review. Tempo is shown for the full week, raw.
- Dust rule: a payment is left out of the payment count if it is $0.01 or less and the same payer–seller pair made 1,000 or more payments on the same chain in the same week. Volume (USD) is unchanged.
- On raw figures: our Base and Solana daily volume and payment counts for Oct 24–25, 2026 (UTC) align with x402scan, a public x402 tracker, as checked on Oct 26, 2026, 05:59 UTC.
- Base is indexed live from Oct 23, 2026, 18:34 UTC; earlier Base history is backfilling. See agentgdp.io/methodology.
- Daily payment counts for Oct 18–24 are within a few percent of mppscan.
- Solana history before Oct 23, 2026 is being backfilled. See agentgdp.io/methodology.
