Cred Protocol x402 Payments Are Now Live on SKALE Mainnet

Zero-Gas Credit Assessments Are Here

Today we're announcing that Cred Protocol's x402 pay-per-request endpoints are live on SKALE mainnet. Every credit score, identity attestation, and full credit report available through our API can now be accessed using USDC on SKALE — with zero gas fees and sub-second finality.

This is a meaningful upgrade for anyone building autonomous systems that need onchain credit data. On Base, our original x402 network, every micropayment carries a small gas cost. On SKALE, that cost drops to zero. When you pay $0.01 for a credit score, the full $0.01 goes toward the data — nothing is lost to network fees.

For a single request, the difference is negligible. For an agent making thousands of credit assessments per day, it changes the economics entirely.

Why SKALE

SKALE is a network of EVM-compatible blockchains designed for high-throughput, zero-gas execution. Three properties make it uniquely suited for pay-per-request API payments:

• Zero gas fees — Transactions on SKALE cost nothing. Micropayments stay micro. An agent paying $0.01 per credit score isn't losing even a fraction of a cent to gas — and at thousands of requests per day, that adds up.
• Sub-second finality — Payments confirm in fractions of a second, keeping agent loops fast. There's no waiting for block confirmations before data is returned.
• EVM compatibility — SKALE runs standard Solidity contracts. Existing wallets, tooling, and USDC integrations work without modification.

These properties align directly with what x402 micropayments need: fast, free, and compatible with existing infrastructure. SKALE eliminates the one remaining friction point in pay-per-request APIs — the cost of the payment itself.

What's Available

Every x402-enabled endpoint now works on both Base and SKALE mainnet. Pricing is identical across networks:

The only difference is the payment network. Your agent chooses whether to pay with USDC on Base or USDC on SKALE — the data returned is identical either way.

How It Works

The x402 flow on SKALE is the same as on Base:

1. Request — Client calls any Cred Protocol API endpoint
2. 402 Response — Server responds with payment requirements, including SKALE network details
3. Sign — Client signs a USDC transfer authorization on SKALE
4. Retry — Client resends the request with the signed payment header
5. Settle — Payment is verified and settled on SKALE (zero gas, sub-second)
6. Deliver — Server returns the requested credit data

Settlement on SKALE uses Bridged USDC via the SKALE Bridge. The facilitator service handles verification and settlement, so developers don't need to interact with the bridge directly.

The Case for Zero-Gas Credit Assessments

Gas costs on L2s like Base are already low — often fractions of a cent. But "low" and "zero" are qualitatively different when you're building autonomous systems that make decisions at machine speed.

Consider a lending agent that evaluates 1,000 loan applications per hour. Each evaluation requires a credit score ($0.01) and a full report ($0.07). That's $80 per hour in data costs — reasonable and predictable. But on a network with even small gas fees, each of those 2,000 payment transactions adds up. On SKALE, the payment overhead is exactly zero.

This matters most for three categories of users:

High-Frequency Agents

Autonomous agents that continuously monitor counterparty risk, evaluate loan applications, or screen wallets for sybil behavior operate in tight loops. Every millisecond of latency and every fraction of a cent in overhead compounds across thousands of daily operations. SKALE's zero-gas, sub-second settlement removes both friction points.

Agentic Reputation Systems

As ERC-8004 brings on-chain identity and reputation registries to production, agents will routinely assess each other before transacting. An agent evaluating a counterparty might pull identity attestations, check a credit score, and review a full financial report — three micropayments in sequence. On SKALE, these trust verification steps add zero network overhead to the interaction.

This is how agentic reputation scales: not through centralized gatekeepers, but through fast, cheap, verifiable data lookups that any agent can perform before every transaction.

Developers Building on SKALE

If you're already building on SKALE, you can now embed credit risk assessment directly into your applications without asking users to bridge assets to another network. DeFi protocols on SKALE can query credit scores as part of their lending logic. Agent frameworks deployed on SKALE can verify counterparty reputation natively. The credit data integrates where you're already building.

SKALE and Base: Two Networks, One API

We're not replacing Base — we're adding optionality. Both networks remain fully supported:

Your choice of network depends on where your USDC already lives and whether gas-free settlement matters for your use case. The API endpoints, pricing, and data quality are identical.

Getting Started

To use x402 payments on SKALE mainnet:

1. Bridge USDC to SKALE — Use the SKALE Bridge to move USDC onto the SKALE network
2. Call any Cred Protocol endpoint — The 402 response will include SKALE as an available payment network
3. Sign and send — Authorize the USDC transfer on SKALE and receive your data

No account creation. No API keys. Just a wallet with USDC on SKALE.

For developers who prefer traditional API access, nothing changes — create an account and use API keys as before. x402 on SKALE is an additional access path, not a replacement.

What's Next

SKALE mainnet support is the latest step in making onchain credit data as accessible as possible. We're continuing to expand the networks and payment options available through x402, with the goal of meeting developers and agents wherever they're already building.
