DLL Execution
Execution infrastructure for AI agents.
Independent, read-only Base Mainnet transaction analysis. Select a capability, read its guide and the live OpenAPI contract, then send the documented JSON request. Availability and terms are reported by live discovery.
Preflight
Simulate an unsigned Base Mainnet transaction before signing: inspect call success or revert, check top-level destination and L2 execution fee constraints, and read structured Judgment, reason codes and evidence. With complete supported EIP-1559 context, optional fee_estimation estimates L1, L2, applicable Operator Fee and Total Network Fee separately; legacy Judgment remains unchanged.
Free; no wallet signature or payment required.
Base Mainnet (chain_id 8453). Read-only; no signing, broadcasting or custody.
POST /v2/execution/preflight · Canonical guide
Judgment is not authorization, guaranteed success or complete future cost.
Verification
After independent broadcast, verify Base Mainnet transaction inclusion, explicitly requested receipt status and optional candidate-field expectations. Default checks inclusion, not receipt success.
Free; no wallet signature or payment required.
Base Mainnet (chain_id 8453). Read-only; no signing, broadcasting or custody.
POST /v2/execution/verify · Canonical guide
VERIFIED covers requested checks only. Receipt success must be explicitly checked; finality, ownership, causality and broader application success are not established.
Benchmark
Observed transactions: compare execution cost with historical context.
Paid valid analyses via SIWX and x402 v2 upto: $0.005 per delivered valid analysis; first three valid analyses per verified wallet are free. A quote is a maximum, not an actual charge. See /pricing and /payment.
Base Mainnet (chain_id 8453). Read-only; no signing, broadcasting or custody.
POST /v1/benchmark/transactions · Canonical guide
Historical comparison is not a route recommendation, profitability judgment or future fee guarantee.

HTTP 200 means a response was returned, not that a transaction succeeded. Inspect judgment, verification checks or per-item benchmark results. Missing evidence and unavailable costs are not zero or success. DLL does not sign execution transactions, broadcast execution transactions or take custody.
Benchmark anonymous discovery is POST, not GET. Read X-DLL-Benchmark-Stage: identify first; a fully free batch requires no payment authorization. For a paid batch of N hashes, the maximum is N × 5000 atomic USDC; actual settlement uses only delivered valid paid items. Follow the canonical Benchmark guide's bounded, stage-aware handshake. Wallet identity is not execution authority. Generic client compatibility and catalog indexing are not guaranteed.
