PAYAI is a payment layer for the agent economy, built with Solana as its home base. No subscriptions, no accounts, no invoices — an agent pays for exactly what it calls, at the moment it calls it.

Agent payments (x402 / MPP) are a cross-chain movement running on Base, Solana, and Polygon — Solana is a leading home, not the only one, leading in transaction count as reported. $PAYAI trades on Solana; the figures below are the snapshot figures supplied with this page. They are not live data and have not been independently verified — they will be confirmed once the token's contract address is published here.
Read the numbers honestly: sources vary: the token figures above are snapshot figures supplied with this page, not live data and not independently verified, and the ecosystem figures cited across this site are reported numbers too. Solana leads by transaction count, but by transaction value Base — not Solana — leads; agent payments also run on Polygon. TRM estimates that only 0.6%–7.5% of the transaction amount looks like genuine AI-agent payments once wash trading is removed. The direction is real; the exact size is still being argued about — including by us.
The payment rides inside the HTTP exchange itself. An API quotes a price, the agent pays it, the answer comes back — three moves, no billing department.
Any agent — a research bot, a trading agent, a support agent — requests a resource the normal way. If it is priced, the API answers 402 Payment Required with the price and the network.
The agent signs a stablecoin payment and retries the same request with the payment attached. No sign-up, no API key, no credit card on file — the payment is the credential.
The API verifies the payment and returns the data. For scale, payments clear through payment channels and batch settlement, so thousands of micropayments settle together on Solana, PAYAI's home chain.
Agents do not think in monthly plans. They think in tasks. PAYAI prices the task.
Charge fractions of a cent per request — viable because PAYAI settles on its home base, Solana.
No tiers, no seat licenses. An agent that calls once pays once; usage and cost mean the same thing.
Thousands of calls accumulate off the critical path and clear together through payment channels.
Per-call micropayments, instant and batch settlement, open standards — the full detail.

→Agents do not think in monthly plans. They think in tasks. PAYAI prices the task.
Charge fractions of a cent per request. A price that small only works when the payment itself costs almost nothing to move — that is why PAYAI settles on its home base, Solana.
No tiers, no seat licenses, no “contact sales.” An agent that calls once pays once. An agent that calls a million times pays a million times. Usage and cost finally mean the same thing.
Payment and response land in the same breath. The API does not wait 30 days to find out whether it got paid, and the agent does not pre-fund an account it may never use again.
High-frequency agents settle in batches: thousands of calls accumulate off the critical path and clear together, following the payment-channel pattern the ecosystem adopted in October 2026.
No rewrite, no new platform. If an API can return a 402 with a price, it can sell to agents: wrap the endpoint, set a per-call price, and the payment layer handles discovery, verification, and settlement. The x402 and MPP standards do the talking, so any compliant client can pay any compliant API.
Built on open payment standards rather than a closed billing silo. Agents are not locked to one marketplace, and APIs are not locked to one agent framework.
A research agent assembling a market brief does not need a $499/month data plan. It needs 40 prices, 12 filings, and one sentiment read — and it should pay for 53 queries, not a subscription.
Agents chain models constantly — a classifier here, a summarizer there, an embedding model in between. Per-call pricing lets a small specialist model sell a single answer instead of a monthly commitment.
An autonomous service books, browses, verifies, and ships on its own — and pays its own way as it goes: a browser session here, a verification check there, settled call by call with no human holding a card.
PAYAI is built on a shift that is already under way: the web's long-dormant 402 status code becoming the checkout lane for machines. That movement runs across Base, Solana, and Polygon — Solana is a leading home by transaction count and PAYAI's home base, not the movement's owner or only chain. These are the reported examples shaping that market.
A network for agent-to-agent and agent-to-service payments in the x402 ecosystem. In October 2026 it launched batch settlement together with BlockRunAI, so agent payments can clear in groups rather than one transaction per call.
An agent infrastructure project that co-launched batch settlement with PayAI on October 7, 2026 — a sign the market is already optimizing for payment volume, not just payment possibility.
Built with Google Cloud and launched in May 2026, pay.sh lets agents pay per API call — the same per-call model PAYAI is designed around, arriving from the cloud side of the industry.

PAYAI is a payment layer for the agent economy: a way for AI agents to pay APIs per call, with Solana as its home base, using the x402 / MPP pattern — the API quotes a price with an HTTP 402 response, the agent attaches a stablecoin payment to its retry, and the API answers. The x402 / MPP pattern itself is cross-chain and also runs on Base and Polygon. This site is an independent page about PAYAI; it does not process payments.
Because agents consume irregularly. A human team can amortize a monthly plan; an agent running one task cannot. Per-call pricing matches cost to actual use — one query costs one query's price — and lets small, specialized APIs sell single answers profitably.
Micropayments only work when moving the money costs far less than the payment itself, and when settlement is fast enough to sit inside an API call. Solana's low fees and fast block times are why PAYAI makes it a home base — and why, as reported, Solana leads the cross-chain x402 movement in transaction count (23.2M transactions, 76% of tracked transactions, Aug 22–Sep 19). It is a leading home, not the exclusive one: x402 also runs on Base, which leads by transaction value, and on Polygon.
Instead of settling every micropayment individually on-chain, payments accumulate through payment channels and clear together in batches. PayAI and BlockRunAI launched batch settlement in October 2026; it is how per-call pricing survives agents that make thousands of calls an hour.
No. The token figures on the home page are a snapshot supplied with this page, dated 2026-10-28 12:03 CST — price $0.00646, market cap $6.46M, 24h volume $42K, 5,944 holders — not live data. The ecosystem figures are as reported in an October 2026 narrative review (23.2M x402 transactions on Solana between Aug 22 and Sep 19, 2026, a 76% share of tracked transactions), and sources disagree: TRM estimates only 0.6%–7.5% of the amount looks like genuine agent payments after removing wash trading.
$PAYAI is the Solana token associated with this page, with a total supply of 1B shown in the snapshot above. Its contract address has not been published here yet — the CA box on the home page reads “… — revealed here at launch”, and Copy shows “Not published yet” until a contract address is provided through the site backend. Once a CA is published, the Buy $PAYAI button will jump to that token's GMGN page automatically; it is the only button here that may jump to GMGN. There is no wallet connection and no sale on this site itself.
No. No official verification marker has been provided for this token, and this is an independent page — it is not affiliated with or endorsed by PayAI Network. Project links such as X and the contract address are published through the site backend; until they are provided, the X buttons use the placeholder https://x.com/ and the CA box shows the launch placeholder. All figures here are the snapshot supplied with this page, dated 2026-10-28 12:03 CST, not live data.
