New pricing: $0.10 per risk assessment

bitfence has repriced its API. A token risk assessment (GET /v1/risk/{chain}/{token_address}) now costs $0.10 USDC, and a contextual, position-aware assessment (POST /v1/risk/contextual) costs $0.20 USDC. The prices were $0.003 and $0.005.

Nothing about the integration changes. Payment still settles per query over the x402 protocol on Base mainnet — an agent sends the request, receives the 402 challenge carrying the current price, signs, and retries. Because the price is read from the challenge on every call, standard x402 clients pick up the new amounts automatically; there is nothing to reconfigure and no key to rotate, because there are no keys.

MCP tool calls are now priced per tool: the full risk assessment tool costs $0.10 and the contextual tool $0.20 per call. The MCP handshake and tool discovery remain free — an agent still pays nothing before its first real query.

One tool is retired: quick_check, which returned a trimmed subset of the full assessment. Agents using it should call analyze_token instead — same price, and the response includes the reasoning, confidence, and flags an agent should be acting on anyway.

The response contract is unchanged: same endpoints, same six chains, same score, recommendation, and reasoning in every assessment.
