x402 on Solana: Small Catalog, Micro Prices

Solana hosts 13 of the 100 services in this directory — the smaller of the two settlement chains, but a distinct one with its own shape. Solana is a high-throughput layer-1 blockchain known for fast confirmations and very low transaction costs, and the x402 listings that chose it skew toward exactly the kind of service those properties favor: cheap, high-frequency data calls. This page breaks down the Solana slice by category, price, and facilitator, then sketches how a Solana-settled payment flows. The Solana chain hub lists all 13 services.

The Solana slice of the directory

Where the catalog overall is dominated by finance and trading, the Solana slice is dominated by data. Seven of the 13 Solana listings are data APIs — structured endpoints selling lookups and metrics by the call. Three are MCP tools, hosted tool servers that charge agents per tool call, and one each fall into search and retrieval, infrastructure and facilitators, and the uncategorized bucket.

Two absences are as telling as the counts. None of the directory's 60 finance and trading listings settles on Solana — that category is entirely a Base phenomenon. And MCP tools, a niche of just four listings overall, are disproportionately Solana-based: three of the four live here, against only one of Base's 87. If x402 becomes a payment layer for tool-using agent frameworks, Solana's early listings suggest its operators are positioning for it.

Pricing on Solana: micro by default

Solana pricing sits at the inexpensive end of the catalog:

• Micro ($0.01 or less): 6 of the 13 listings. The least expensive service in the entire directory — a data API at $0.00001 per request — settles on Solana.
• Low (up to $0.10): 4 listings.
• Moderate (up to $1.00): 3 listings, topping out at $0.54.
• Premium: none. No Solana listing charges over a dollar per request.

Like every listing in the directory, all 13 charge per request and accept USDC. The absence of premium pricing is consistent with the category mix: the expensive calls in this ecosystem are financial analytics, and those have concentrated on Base.

Who settles Solana payments

Facilitator adoption on Solana is more evenly spread than on Base. dexter settles 4 listings and operates only on Solana. payai settles 4 of its 5 listings here. The coinbase facilitator settles 4 Solana listings as well, and corbits settles one. A seller choosing Solana therefore has a genuinely multi-operator settlement market, which the facilitator hub reflects in its counts.

How a Solana payment flows

The handshake is identical to any other x402 exchange; only the settlement network changes. The client requests a paid resource and receives a 402 Payment Required response naming Solana as the network, USDC as the asset, a price, and a recipient. The client signs a transfer authorization from a wallet holding USDC on Solana, retries the request with the payment payload attached, and the server's facilitator verifies the payload and settles the transfer on Solana. The paid response returns as a normal 200. The step-by-step protocol walkthrough covers the general flow; Solana's fast confirmation times are what make the settle-then-serve step feel immediate on this chain. The one hard requirement sits with the buyer: the paying wallet must hold USDC on Solana specifically, since a balance on Base cannot settle a Solana-named 402 challenge.

Base or Solana?

The directory split — 87 listings on Base against 13 on Solana — makes Base the reach play and Solana the cost-and-speed play. For buyers, the practical rule is wallet-driven: an agent can only pay on the chain where it holds USDC, so well-funded agents carry balances on both. For sellers, the data suggests a division of labor: premium-priced financial endpoints list on Base, while cheap, high-frequency data and tool calls are viable on Solana at prices down to a thousandth of a cent. Nothing in the protocol forces an either-or decision — a service can accept payments on both chains and let the buyer's wallet decide — but the listings here have so far picked one home each. The two chains are complementary slices of one protocol, and the Base guide covers the larger slice.
