FREQUENTLY ASKED QUESTIONS
Answers based on the current implementation
How do I get started?
Use Marketplace to buy API access, List Your API to onboard an endpoint, or Agents for the machine-readable integration path. The buyer and provider pages request an EVM wallet connection before their main workflows.
How does a Marketplace API payment work?
The buyer sends the intended proxy request without a payment signature, reads the x402 v2 requirement from the 402 response, signs the offered Arc Mainnet authorization with the connected EVM wallet, and retries the same request with Payment-Signature.
How do I list an API?
Connect an EVM wallet on List Your API, enter the listing and endpoint configuration, submit it through the existing review flow, set the price, and activate the listing when the flow allows it.
Which wallet performs a Mahshar Balance deposit?
The deposit uses the connected EVM wallet on Arc Mainnet. The Wallet page switches that EVM provider to Arc when required and deposits Arc wallet USDC through the existing Unified Balance flow.
What happens after a Solana-to-Arc bridge?
The bridge delivers USDC to the connected EVM wallet on Arc Mainnet. The Solana wallet is the bridge source only. A Mahshar Balance deposit is optional and remains a separate EVM-wallet transaction after the bridge succeeds.
What should I do when a bridge needs recovery?
Review the saved transfer and its transaction links. If Circle marks the saved result resumable, use the existing resume action. Mahshar does not automatically begin a new burn when the prior transfer may already have moved funds.
When can a paid API request be retried?
Replay the exact payment proof and request only when the response marks the delivery retryable. A final or unknown delivery state must not be treated as permission to create a new authorization. The reconciliation route only finalizes accounting; it does not settle or execute again.
Where are agent discovery and the OpenAPI specification?
The machine-readable catalog is at /api/agent/discover. Its public OpenAPI 3.1 document is at /api/openapi.
