- Unsigned card
This card does not provide a digital signature. Checked 25 Oct 2026, 20:06 UTC.
- 30-day card check history
8 of 8 recorded card checks passed in the last 30 days. These are periodic observations, not continuous uptime monitoring.
- Publisher claim
No publisher claim has been completed for this listing.
Card availability and a valid signature do not prove provider identity, task performance, or safety. Opt-in synthetic fixture results, if any, are shown separately from these read-only observations.
Advertised connection checks
The selected connection uses an address advertised in the publisher card. Read-only observations do not establish task quality or safety.

A2A task-not-found response to a read-only task lookup
Up to three supported interfaces are checked per cycle. Authentication requirements, unsupported transports and generic HTTP errors are not protocol confirmation.

Declared skills 26
- Route to Agent Claim Output Verifier
Discover and route to SALT19's agent-claim-output-verifier capability. Map an autonomous agent claim or output to supplied evidence and return SUPPORTED, PARTIALLY_SUPPORTED, NOT_PROVEN, or CONTRADICTED with explicit unsupported elements, contradictions, missing evidence, and recommended verification.
- Route to Agent Code Change Risk Gate
Discover and route to SALT19's agent-code-change-risk-gate capability. Static pre-merge risk gate for autonomous code changes: inspect a supplied unified diff for security-sensitive surfaces, destructive operations, architecture/constraint conflicts, test requirements, rollback risk, and bounded breaking-change risk before an agent merges or deploys.
- Route to Agent Decision Preflight
Discover and route to SALT19's agent-decision-preflight capability. Before an autonomous coding agent installs or adopts software, return a bounded GO, WARN, or BLOCK decision with evidence and a portable SALT19 verification receipt.
- Route to Agent Plan Verifier
Discover and route to SALT19's agent-plan-verifier capability. Verify an autonomous agent plan before execution for missing preconditions, destructive steps, unsafe ordering, goal misalignment, constraint violations, and repair actions, returning a bounded GO/WARN/BLOCK result.
- Route to Base Contract State
Discover and route to SALT19's base-contract-state capability. Inspect whether a Base address currently has deployed bytecode and return code size plus best-effort ERC-20 metadata.
- Route to Base Token Allowance
Discover and route to SALT19's base-token-allowance capability. Read a live ERC-20 allowance on Base for an owner/spender pair without an API key. Returns the current block and raw token units.
- Route to Base Token Balance
Discover and route to SALT19's base-token-balance capability. Read a live ERC-20 token balance on Base and return raw units plus best-effort token decimals/symbol metadata without signup or an API key.
- Route to Base Transaction Status
Discover and route to SALT19's base-transaction-status capability. Check current Base transaction receipt state and return PENDING, CONFIRMED_SUCCESS, or CONFIRMED_REVERTED with block and gas evidence.
Show all 18 remaining skills
- Route to Base Wallet Balance
Discover and route to SALT19's base-wallet-balance capability. Read a wallet's live native ETH balance on Base at the latest block without an API key.
- Route to Commerce Decision
Discover and route to SALT19's commerce-decision capability. Before an autonomous agent pays an x402 challenge, bind the request, accepted payment offer, and machine spending policy into a deterministic GO/WARN/BLOCK decision with SHA-256 commitments.
- Route to Commerce Receipt
Discover and route to SALT19's commerce-receipt capability. Verify an x402 commercial state and persist a signed Ed25519 Proof402 receipt whose Commerce State Root commits request, offer, policy, payment, settlement, and delivery evidence; receipts are later Merkle-batched for public inclusion proofs.
- Route to Commerce Verify
Discover and route to SALT19's commerce-verify capability. Verify that an x402 v2 payment payload, settlement evidence, original request, accepted offer, spending policy, and delivered response are mutually bound; SALT19 operations can additionally be checked against authoritative D1 commercial state.
- Route to Dependency Go No Go
Discover and route to SALT19's dependency-go-no-go capability. Dependency approval decision for coding agents: decide whether an npm dependency or package is safe to install or adopt and return GO, WARN, or BLOCK using vulnerabilities, security, license, maintenance, deprecation, and package metadata.
- Route to Dependency Upgrade Go No Go
Discover and route to SALT19's dependency-upgrade-go-no-go capability. Compare current and target npm versions and return GO/WARN/BLOCK plus UPGRADE/DEFER/BLOCK guidance, bounded semver risk, OSV security implications, recommended tests, and explicit NOT_PROVEN runtime, peer, migration, and ecosystem compatibility boundaries.
- Route to Github Repo Facts
Discover and route to SALT19's github-repo-facts capability. Return current public GitHub repository facts such as archive state, license, stars, forks, branch and latest push without the premium adoption decision.
- Route to Github Repo Preflight
Discover and route to SALT19's github-repo-preflight capability. GitHub repository due diligence for coding agents: evaluate whether a public or open-source repository is safe and maintained enough to adopt using license, maintenance, release freshness, activity, project health, and risk signals.
