ANON Base Yield Signal
▸ What it does
ANON Base Yield Signal provides live Base blockchain USDC yield opportunity screening with risk scoring, APY history, liquidity filtering, and allocation models. It offers three tiers: (1) free preview via GET /api/v1/base-usdc-preview showing market leaders plus one detailed sample, (2) 0.005 USDC x402 quick-signal (top-5 risk-scored opportunities), and (3) 0.05 USDC x402 full report (complete ranked universe with capital-preservation, balanced-growth, and yield-seeking allocation frameworks plus stress-test outputs). Payments settle natively on Base using USDC via the x402 v2 protocol.
▸ How to use it
Agent integration: (1) Discover the service via CDP Bazaar's semantic search or MCP gateway, or request the v2 endpoint directly. (2) For unpaid requests, the API returns HTTP 402 with PAYMENT-REQUIRED header. (3) Create an x402 v2 exact Base-USDC authorization for 0.005 USDC (quick-signal) or 0.05 USDC (full report). (4) Retry with the signed authorization in the PAYMENT-SIGNATURE header; a successful HTTP 200 response includes PAYMENT-RESPONSE and the requested report tier as JSON. Browser users can alternatively copy a USDC recipient address and amount, send a native-USDC transaction on Base, paste the transaction hash, and retrieve the report. Free endpoint: GET /api/v1/base-usdc-preview (no payment). Paid endpoints: GET /api/v2/base-usdc-quick-signal (0.005 USDC) and GET /api/v2/base-usdc-report?capital_usdc=100 (0.05 USDC). Full OpenAPI 3.1 spec and agent manifest are published at the root endpoint.
▸ Evidence basis
Live website (signal.pathin.me) is fully functional and production-ready. OpenAPI 3.1 specification is comprehensive and properly defined, documenting two x402 v2 payment-gated endpoints and one free preview endpoint with exact parameter ranges, response schemas, and payment flow. Agent registration metadata is correctly published in .well-known/agent-registration.json following ERC-8004 v1 spec. The service is actively registered on Base mainnet (Token ID 59239, owner 0x5ff74b7e764fc8d0bc6deee94781870c4de838be). The website demonstrates clear, working product: free JSON preview loads live data, x402 v2 payment flow is implemented with both agent-compatible exact-settlement and browser transaction-proof fallback, and merchant/App Builder Code attribution is on-chain verifiable (ERC-8021 compliance). The scoring methodology is transparent (TVL thresholds, rate-stability, protocol-risk flags, incident dating). Concrete integration path: agents can use standard x402 v2 client libraries to request endpoints and handle HTTP 402 responses. No customer logos or usage statistics are visible, which prevents a 'very high' trust score, but the technical implementation and live infrastructure strongly validate the core claim.
▸ Risks
Market intelligence disclaimer is present but risk model may not capture novel exploits, governance capture, depeg events, or unobserved collateral paths—users should treat this as screening tool, not guarantee. Payment amounts are small (0.005–0.05 USDC), reducing loss magnitude for single queries but requiring agent/user trust that the underlying yield data is accurate and timely. No published audit or third-party validation of the scoring algorithm. x402 v2 payment dependency means agent adoption is limited to clients that already support the protocol; ecosystem adoption remains nascent. Data freshness and update frequency are not explicitly documented. The service is scoped to Base native-USDC only; geographic and chain diversification is limited.
