On May 5, 2026, the Solana Foundation announced the launch of Pay.sh — a marketplace where AI agents can discover listed APIs and make wallet-authorized, per-request stablecoin payments on Solana. The launch announcement covered selected Google APIs and 50+ community APIs; current availability is determined by the live catalog.

We're proud to be a launch partner.

Pay.sh launched with services from multiple agentic payment facilitators on Solana, including PayAI. PayAI-indexed services were discoverable through Pay.sh when included in its catalog; a PayAI integration by itself did not guarantee a listing or permanent availability.

What this actually means

Builders shipping autonomous agents repeatedly face two practical questions:

  1. How does my agent find the right API?
  2. How can it authorize and pay for the call within a controlled workflow?

Both PayAI and Pay.sh address service discovery and payment settlement for agents. PayAI facilitates compatible services and maintains its own discovery surfaces. Pay.sh provides a separate catalog and wallet-paid gateway for services listed there.

A compatible Pay.sh client can discover a listed service, receive a quote, and make a wallet-authorized call in one workflow. That can remove the need for a separate consumer API key to the listed upstream API; it does not remove wallet setup, funding, or spending authorization.

What the May 2026 launch included

The May 5 launch announcement named selected Google APIs (including Gemini, BigQuery, Bigtable, Cloud Run, and Vertex AI Model Garden) alongside 50+ community APIs across commerce, data, communications, and Solana infrastructure.

Launch-day examples attributed to PayAI included:

  • Nansen — onchain intelligence, wallet labels, smart money flows. Your trading agent can pull real signals before it executes.
  • Blockrun — a pay-per-call AI gateway. 55+ models plus a service marketplace, all callable through one endpoint with no API keys.
  • Sponge — agent payment infrastructure from ex-Stripe engineers. Businesses upload their API spec and agents can autonomously sign up and pay for usage, no credentials required.
  • Laevitas — institutional-grade crypto derivatives data. Options, futures, and perpetuals across 15+ exchanges, callable per request so a strategy agent can price volatility on demand instead of paying for an enterprise seat.
  • Xona — creative AI for agents. Per-use image, video, and brand kit generation, priced per pixel through x402.
  • OnVoyage — Generative Engine Optimization. Lets agents query and improve how brands show up across ChatGPT, Claude, Gemini, and Perplexity.

These were launch-day examples of services designed for software callers. Their descriptions reflect how they were presented at launch, not a verified live compatibility or availability matrix. Check Pay.sh's current catalog and each provider's current documentation before integrating.

Why this matters

"Pay.sh is the discovery layer the agentic web has been missing. Agents don't read landing pages — they query catalogs. Every API that wants to be used by autonomous software needs to be indexed, priced per request, and payable in real time. PayAI has been building toward exactly this future on Solana, and the fact that the Foundation is now aggregating across facilitators in a single catalog is a meaningful step forward for the whole ecosystem. We're going to ship a lot more from here."
— Notorious, founder at PayAI (@notorious_d_e_v)

Solana combines low transaction fees and fast confirmation with stablecoin liquidity. Confirmation is not the same as finalized settlement; applications should choose their commitment level for the risk they accept. These properties make Solana a practical rail for per-request agent payments, without implying it is the only chain capable of supporting them.

For builders

If you're building an agent: try Pay.sh. Follow Pay.sh's current setup documentation to install the client, configure and fund a wallet, and start with the smallest useful call. Mainnet payments require user authorization unless you deliberately configure an automation policy.

If you're an API or service provider: integrate with PayAI using the maintained documentation. A PayAI integration does not by itself guarantee a Pay.sh catalog listing; check Pay.sh's current provider and registry requirements. PayAI docs: docs.payai.network.
