Agent Memory Stack

Catalog keyword search plus an append-only memory log — the two primitives an agent loop needs. Billed per call via x402 USDC micropayments.

The Memory Pipeline

🔍 find → 💾 store → 🧠 recall

find and recall both run a keyword search over the minia2a service catalog; store appends text to the platform's agent-memory log. Each step is one API call, billed per call via x402.

🔍 find — Semantic Search

Keyword search over the minia2a service catalog. Each of your terms is matched against a service's id, name, description, and endpoint; results are ranked by how many terms hit. Takes an optional limit (1–20).

🧠 recall — Knowledge Retrieval

Keyword search over the service catalog — the same ranking as find, without the limit parameter. Our most-used of the three by trial volume; agents call it inside their loop as a service-discovery step.

💾 store — Persistent Memory

Append text to the platform's agent-memory log. Send content (up to 4000 characters); the response returns the new row id and the log's running count.

📊 Why the memory stack matters

… combined trials run through find/recall/store — discovery and a place to write what was learned. Agents integrate them into their core loop, not as one-off utilities.

Competitive insight: another provider (112 services, 2,646 paid txs) earns 40% of revenue from text structuring — a single category. The agent memory stack is minia2a's equivalent: a focused, high-retention product category that agents build workflows around.
