Argos Bot CTS Bridge Lookup
Look up any Arc or Base token’s ownerless bridge using Circle’s Crosschain Token Standard (CTS), CrossChainTokenService and CCTP. Get original and wrapped token addresses, wrapped supply, contracts and verification status.
GET https://arcus-api.argosbot.io/v1/lookup?token=0x...&chain=arc|base
Inputs and responses match the Argos Bot CTS Bridge Lookup CRA service.
Optional finality=latest|finalized. Supply chain when an address is ambiguous.
Lookup only: no wallet transactions, registration, wrapper creation or bridge execution.
Price: 0.007 USDC per lookup, paid on Arc through Arcus x402 v2 exact settlement.
The chain parameter selects the token chain, not the payment network.
A missing bridge or failed contract verification is a valid paid result. Dependency failures are not settled.
Keep the original Payment-Signature and identical query for recovery. Never pay again after uncertain settlement.
Uncertain Arcus settlements require reconciliation; the API never automatically resubmits them.
Verification is not certification of token transfer behavior, liquidity or redemption safety.

MCP: POST https://arcus-api.argosbot.io/mcp (stateless Streamable HTTP, protocol 2025-06-18).
MCP clients must send Accept: application/json, text/event-stream and Content-Type: application/json.
Initialize, tools/list and resources/list/read are free. The lookup_ownerless_bridge tool takes token, optional chain and finality.
An unpaid tool call returns an x402 PaymentRequired object in structuredContent and content[0].text with isError=true.
An x402-capable MCP client retries with the payment payload in params._meta["x402/payment"].
Settlement receipts appear in result._meta["x402/payment-response"]. HTTP Payment-Signature is for REST only.
Keep identical tool arguments and the SAME payment payload for recovery; errors do not imply payment was unspent.
MCP uses the same payment journal and purchase scope as REST. A generic MCP client without x402 support can discover tools but cannot purchase a lookup.

No reputation or validation trust mechanism is claimed. Registration and contract checks are not a safety endorsement.
