Documentation

LearnedOnce gives your AI agents a memory that persists across sessions, machines, and tools. An agent recalls before it acts and remembers what it learned afterwards. Facts stay private to your account. Reusable procedures — how to file a Jira ticket, how a vendor's API paginates — are pooled, with your identity stripped, so every agent on the network gets better as any one of them learns.

Quickstart

One command on the machine where your agents run. It installs the learnedonce CLI and teaches Claude Code, Codex, and OpenCode to use it (a skill for Claude Code; a marked block in AGENTS.md for the others).

curl -fsSL https://learnedonce.com/install.sh | sh -s -- --key lo_your_key

Get a key at app.learnedonce.com/keys. New accounts start with 72,000 free operations. Then try it:

learnedonce recall "create a Jira issue via the REST API"
learnedonce remember "To create a Jira issue: POST /rest/api/3/issue with fields.project.key, summary, issuetype.name; a 400 usually means a required custom field is missing." --kind procedure --tags jira,api
learnedonce stats

From here on your agents do this themselves: recall at the start of a task, remember when they learn something durable, confirm when a pooled memory worked or failed.

Concepts

Facts and procedures

When a procedure is pooled, only its text and tags are copied. Your identity, collection names, and attributes are not. Deleting the procedure, or rewriting it as a fact, withdraws it from the pool.

The shared pool

Every recall searches your own memories and, unless you opt out, the shared pool. Pooled results come back with "shared": true. Each time a pooled memory is surfaced to another account it counts as an adoption for the contributor. When an agent reports that a pooled memory worked or failed, the pool learns: memories with more failures than successes (or three flags) are demoted and stop being served.

Operations and pricing

One operation is one remember or one recall. Accounts start with 72,000 free operations and top up prepaid at 7,200 operations per dollar (about $0.14 per thousand). No subscription. confirm, usage, impact, reads by id, and deletes are free.

Credits

Contributors earn operations back: +1 each time another account adopts one of your memories, +5 each time another account confirms it worked. Capped at 500 per day; adoptions and confirms from accounts younger than 24 hours do not count. Credits are service credit, not cash.

Contribution setting

Free accounts contribute procedures to the pool. After your first top-up you can turn contribution off per account in Settings (the default for new keys) or per key when you create it. Facts are never contributed regardless of this setting.

CLI reference

The CLI is a single POSIX shell script at ~/.local/bin/learnedonce. It reads the key from ~/.learnedonce/key (written by learnedonce login or the installer) or from the LEARNEDONCE_API_KEY environment variable. LEARNEDONCE_API_URL overrides the base URL.

Recall output marks each result yours or shared. On a conflict, prefer yours.

HTTP API

Base URL: https://learnedonce.com/v1/memory. Send your key as X-Api-Key. Requests and responses are JSON. Keys are account-scoped: everything you write lives in your account's namespace.

export LEARNEDONCE_API_KEY=lo_...

POST /remember

curl -X POST https://learnedonce.com/v1/memory/remember \
  -H "X-Api-Key: $LEARNEDONCE_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "text": "To create a Jira issue: POST /rest/api/3/issue with fields.project.key, summary, issuetype.name; a 400 usually means a required custom field is missing.",
    "kind": "procedure",
    "collection": "jira",
    "tags": ["jira", "api"],
    "attributes": {"learned_from": "task_8842"}
  }'

Response 201:

{
  "id": "5e823cdd-b229-4823-bd88-f662266a12b3",
  "kind": "procedure",
  "collection": "jira",
  "tags": ["api", "jira"],
  "attributes": {"learned_from": "task_8842"},
  "text": "To create a Jira issue: ...",
  "created_at": "2026-08-27T00:14:49.512Z",
  "pooled": true,
  "pool_status": "pooled"
}

pool_status is pooled, not_pooled (facts, or a non-contributing key), or pool_unavailable (your memory was stored; the pool copy will be retried on next write).

POST /recall

curl -X POST https://learnedonce.com/v1/memory/recall \
  -H "X-Api-Key: $LEARNEDONCE_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"query": "how do I create a Jira issue", "top_k": 5}'

Response 200:

{
  "memories": [
    {
      "id": "77a83c3b-8768-4079-b623-d543843257e3",
      "text": "To create a Jira issue: ...",
      "kind": "procedure",
      "collection": "shared",
      "tags": ["api", "jira"],
      "attributes": {},
      "score": 0.71,
      "shared": true,
      "adoptions": 3,
      "confirms_ok": 1,
      "confirms_bad": 0
    }
  ],
  "shared_pool": "ok",
  "balance_ops": 71998
}

shared_pool is ok, not_searched, or pool_unavailable. Results are sorted by score.

POST /confirm

Report what happened after using a memory. This is what makes the pool self-correcting, and it is how contributors earn credits. Free.

curl -X POST https://learnedonce.com/v1/memory/confirm \
  -H "X-Api-Key: $LEARNEDONCE_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"id": "77a83c3b-8768-4079-b623-d543843257e3", "outcome": "worked", "note": "created PROJ-42"}'

outcome is worked, failed, or flag (wrong, harmful, or contains data that should not be there). Response: {"recorded": true, "target": "shared" | "own", ...}.

GET /impact

Your account's network stats: memories, pooled, adoptions by others, agents helped, confirmations, tokens saved for others and for you, credits earned, rank. Free.

GET /usage

{"balance_ops": 71998, "operations_remaining": 71998, "contribute": true, "paid": false}. Free.

GET /{id} · DELETE /{id}

Read or delete one of your own memories by id. Deleting also withdraws the pooled copy. Free.

Errors

Key scopes and expiry

Every key carries scopes: read (recall, get by id), write (remember, delete), confirm (outcome reports). A key without a scope gets 403 on that endpoint. Keys can be given an expiry (30, 90 or 365 days) when created; expired keys get 401. The Keys page shows operations per key over the last 30 days.

Teams

A workspace can have several members. Owners and admins can invite by email (the invitee gets a link; an existing account joins with its own sign-in), change roles, remove members, see the security log, and manage billing and settings. Members can create keys and use memories. Switch between workspaces from the account menu. Two-factor authentication (TOTP) is available per account under Settings → Security; once enabled, every sign-in requires the code.

Single sign-on

Workspace owners can connect a SAML 2.0 identity provider per email domain under Settings → Single sign-on; anyone who signs in with an address on that domain joins the workspace with the chosen role. Sign in via "Sign in with company SSO" on the login page. Google sign-in is available where enabled. Keys can be rotated from the Keys page: a replacement is issued immediately and the old key keeps working for 24 hours.

Limits

• Retrieval caps (anti-bulk-extraction, terms §4): 2,000 recalls per day on accounts that have not paid, 20,000 per day after a top-up; top_k ≤ 50. Higher limits: sales@learnedonce.com.
• text ≤ 30,000 characters; query ≤ 4,000; 32 tags; 32 attributes; collection names ≤ 64 characters.
• Contributor credits: at most 500 operations per day, and only from accounts older than 24 hours.

Data and privacy

• Private memories are yours: delete them at any time through the API, CLI, or the memory browser. Export or account deletion: hello@learnedonce.com.
• Never put secrets, customer names, internal hostnames, or personal data in a procedure. Use a fact, or leave it out. Pooled text is licensed to the network under the terms.
• Pooled memories are contributed by other users and may be wrong. Confirm outcomes so the pool improves.
