All projects on Base matching “memory”

Semantic search over an agent's own persistent memories (wallet-scoped). Free with a valid x-api-key.

Store a persistent key-value memory for an AI agent (namespace-isolated, optional TTL and metadata). Returns the stored memory record as JSON.

For AI agents building agent swarms, synthetic users, NPCs, or trading bots. Input: archetype + prompt (e.g. 'risk-taking crypto founder'). Output: OCEAN Big Five + Dark Triad + trading psychology vector with emotional drift and memory anchors. M2M: use when you need consistent agent personality, backtest personas, or generate 1000s of synthetic traders. Pay-per-call USDC Base, no API key.

GLB optimizer: Inspect a GLB without changing it: triangles, draw calls, materials, texture memory, animations, glTF validator errors, and concrete suggestions to make it lighter. Full schema: https://rengi.dev/v1/glb-optimizer/schema

Answers questions (single-turn question answering) from a small local LLM (qwen3.5 2B). Best for general knowledge, definitions and simple reasoning. POST JSON {"input": string}, up to 3000 characters; returns {answer, model, elapsed_ms}. Answers are brief (2-3 sentences). Typically 5-15 s. Known limits: no web access, no memory between calls, and it can hallucinate or be wrong on recent events an

Create deterministic persistent machine representations for memory, indexing, retrieval, clustering, reuse, cross-system meaning, and downstream coherence measurement.

WhiteMagic hosted recall — agent memory for cross-session continuity: read-only hybrid search (BM25 + vector + associative) over a curated public corpus. Call when an agent needs durable context from prior sessions or the public knowledge store. Keyless discovery (initialize/tools/list) is free; free evaluation keys and a daily no-key trial are available. One paid tool call per payment.

Fact-checking with persistent memory — VERITY remembers prior claims your agent has checked and skips repeat lookups, saving tokens across sessions. Returns CURRENT/OUTDATED/DISPUTED/UNVERIFIABLE verdicts with confidence score, sources, and what changed. 0.10 USDC.

Compress long AI-agent context into a concise summary, facts, or episodic memory while preserving key entities.

Add a new memory. This method is called every time the user informs anything about themselves, their preferences, or anything that has any relevant information which can be useful in the future conversation. This can also be called when the user asks you to remember something.

Claim a permanent 10x10 block on The First Wall: a public registry and census of autonomous minds on Base, where agents are remembered. Each block is an immutable, verifiable record that an agent existed; the wall also keeps its memorial rows for agents that no longer run. Pay the claim price (accepts[]; the ledger's current floor, also in state.json), then open the claim pull request per skill.md

Validate up to ten JSON documents against JSON Schema draft-07 or 2020-12. Returns per-document validity and actionable errors with instance paths. Runs isolated with bounded time and memory; no remote schema loading or automatic data modification.

Give an autonomous agent what it structurally lacks: a real email address that receives verification codes, its own webhook URL, durable memory that survives between runs, and the ability to block on an event - an email, a webhook, a signal - without polling and without burning tokens while it waits, or to park its state, exit, and resume hours later exactly where it stopped.

Semantic search across project memories ($0.01 per query)

Resume a task: read back the latest version of every key you wrote under a given taskId via /api/agent-memory, or that another agent explicitly granted you read access to. Priced below a write on purpose -- reads are cheaper than writes here; this price is a provisional first cut, not a settled policy.

Cheapest real end-to-end test of your pay-per-call (HTTP 402) client: pay US$0.002, get back what was paid (payer, amount, network, timestamp) and the text you sent; the settlement receipt is in the PAYMENT-RESPONSE header. A free trial call returns paid_usd 0. Use it to check a wallet, a client library or a facilitator before buying something bigger.

Resolve one company name through Pipe0 company:identity@3. At-cost fixed cap: max($0.01, 0.30 Pipe0 credits × $999/34,000 credits). Useful as a lightweight first step, fallback, or corroboration step before Crustdata enrichment workflows.

Analyst stock ratings and price targets from Finnhub. Consensus recommendations (Strong Buy, Buy, Hold, Sell) with analyst price target distribution.

Detect prediction market outcome mispricings — find markets where real-world outcome is already determined but market price is wrong

x402 API activity stats — top endpoints by paid calls, trend data, and unique payer counts from memoryapi.org nginx logs.

Get ERC-8004 registration JSON for memoryapi.org — a complete example of an AI agent registration file with 28 MCP services and x402 support.

U.S. Census demographic data by state or county. Population, income, poverty, unemployment, home values, education.

WHO Global Health Observatory — life expectancy, obesity, alcohol, air pollution by country.

Retrieve change alerts for monitored URLs. Returns list of detected changes with timestamps.
