## Tools (as reported by the server, not verified)

- `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. Your first 3 each day
- `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 \(block\). Every workspace a
- `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 is created; buying a w
- `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 workspace key in \_meta\[
- `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 workspace key in \_met
- `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 key in \_meta\[satledg
- `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\[satledger/api-key\].
