DeFi strategy backtesting via x402 micropayments on Silverback's autonomous intelligence API.
What it does
Silverback's `/api/v1/backtest` endpoint is part of a suite of 11 pay-per-use DeFi intelligence endpoints accessible via the x402 micropayment protocol. The broader Silverback API provides autonomous DeFi infrastructure including swap routing, liquidity analysis, yield optimization, technical analysis, token audits, whale tracking, and more. Payments are settled in USDC on Base, Solana, or SKALE networks, with an optional 15% discount when paying with the $BACK token via Permit2 on Base.
The `/api/v1/backtest` endpoint specifically is not documented in the published OpenAPI spec (which covers 11 other endpoints) and returned 404 on both POST and GET probes. This means the endpoint may have been removed, renamed, or is not yet live. No schema, pricing, or response format information is available for this specific path. The broader Silverback API is live (root returns 200, other endpoints are documented with full OpenAPI 3.1.0 schemas), so the platform itself is operational — but this particular backtest endpoint cannot be confirmed as functional.
Pricing for other Silverback endpoints ranges from $0.01 to $0.05 per call depending on complexity tier. If the backtest endpoint follows the same pattern, it would likely fall in the heavy analysis tier ($0.03) or higher, but this is speculative. All Silverback responses include a `success: boolean` field and return JSON.
Capabilities
Use cases
- —Backtesting DeFi trading strategies before deploying capital
- —Evaluating historical performance of token swap strategies
- —Agent-driven portfolio optimization through historical simulation
Fit
Best for
- —AI agents needing pay-per-use DeFi backtesting without subscriptions
- —Autonomous trading systems that settle API costs in USDC micropayments
- —Developers prototyping DeFi strategies with historical data
Not for
- —Users needing a currently live and documented backtest endpoint (returns 404)
- —Real-time trade execution (see /api/v1/swap instead)
- —Free or subscription-based API access
Quick start
# This endpoint currently returns 404 — it may not be live.
# For working Silverback endpoints, try /api/v1/technical-analysis:
curl -X POST https://x402.silverbackdefi.app/api/v1/technical-analysis \
-H 'Content-Type: application/json' \
-d '{"token": "ethereum", "timeframe": "7"}'Endpoint
Quality
The specific /api/v1/backtest endpoint returned 404 on both POST and GET probes and is absent from the published OpenAPI spec. No schema, pricing, or response documentation exists for this path. The broader Silverback platform is live and well-documented, but this particular endpoint cannot be confirmed as functional.
Warnings
