  • timestamp_receipt

    Submit a SHA-256 digest and receive a Time-Stamp Authority's signed RFC 3161 token over it: evidence that the data you hashed existed at that time, verifiable against the authority without trusting or contacting this service. Hash your data yourself - it never leaves your side.…

  • provision_workspace

    Buy a workspace: a tamper-evident usage and action ledger for your agents, every event ed25519-signed and hash-chained, with an export your own customers verify offline. Pay over x402 in _meta[x402/payment]: 0.50 USDC for 2,500 units (starter), 15.00 USDC for 100,000 units (bloc…

  • top_up_workspace

    Add units to a workspace you already hold. Send its API key in _meta[satledger/api-key] (or the api_key argument) and the payment in _meta[x402/payment]: 0.50 USDC for 2,500 units (starter), 15.00 USDC for 100,000 units (block). The units land in that workspace and nothing new i…

  • create_agent

    Create an agent in your workspace: a named ledger whose every event is ed25519-signed and hash-chained. `initial_credits` mints supply to the workspace issuer, not to the agent - fund_agent moves credits across when you need usage metering. Costs 1 unit. Authenticate with the wo…

  • record_action

    Append what an agent did - a tool call, a decision, a message - as a signed, hash-chained entry. This is the thing the workspace is for. Costs 1 unit. Authenticate with the workspace key in _meta[satledger/api-key].

  • fund_agent

    Move credits from the workspace issuer to an agent's own account, so record_usage can burn them. Costs 1 unit. Authenticate with the workspace key in _meta[satledger/api-key].

  • record_usage

    Burn credits from an agent's account, as a signed ledger event. Costs 1 unit. Authenticate with the workspace key in _meta[satledger/api-key].

  • anchor_agent

    Ask a public RFC 3161 Time-Stamp Authority to sign the agent's current state. The one fact here the operator cannot manufacture: a timestamp cannot be issued for a time that has passed. An unchanged state returns the anchor it already has. Costs 100 units. Authenticate with the…

  • export_agent

    Build the export bundle, run the customer-side verifier over it and return the summary plus the URL of the archive (HTTP, X-API-Key, free). Pass expect_action_head / expect_action_count from state YOU kept to check completeness. Free, permanently. Authenticate with the workspace…

  • list_agents

    Every agent in your workspace. Free. Authenticate with the workspace key in _meta[satledger/api-key].

  • describe_agent

    Current state: root id, state hash, event count, balance. Free. Authenticate with the workspace key in _meta[satledger/api-key].

  • list_actions

    The agent's action log, with its head hash. Free. Authenticate with the workspace key in _meta[satledger/api-key].

  • list_anchors

    Every anchor commitment recorded for the agent. Free. Authenticate with the workspace key in _meta[satledger/api-key].

  • workspace_balance

    Units remaining and what each operation costs. Free, so you can plan before you are refused. Authenticate with the workspace key in _meta[satledger/api-key].
