DocDeploy — One source of truth. Every agent.

# Doc Deploy > Portable, encrypted, **free-to-start** memory for AI agents — and pay-per-call documents that go with it. One source of truth, every agent. Write from Claude, recall from Codex, share with Cursor: memories live at a neutral endpoint (services.docdeploy.io), not inside any one vendor. **Tier 1 (free): 100 writes + 1000 reads per tenant per UTC day.** Tier 2: when the free quota burns, memory routes fall through to per-call USDC on Base via x402 (~$0.002–$0.010 each) and keep working. Tier 3: enterprise flat-rate plans skip both quota and per-call charges. Documents (PDF, DOCX, etc.) are pay-per-call from call 1 — no free tier. No subscriptions, no surprise invoices. ## Discovery endpoints (no auth, no payment) - [Agent skill spec](https://docs.docdeploy.io/skill.md): **READ THIS FIRST.** Single-document, fetch-once spec (v1.2) covering capabilities, authentication, and the **MCP dispatcher pattern**: paid MCP tools return a `status: "payment_required"` success result with an `execute_via` block naming the wallet tool (paysponge:x402_fetch or any x402-aware fetcher) the agent should call next — NOT an MCP error. Also covers the underlying x402 envelope for direct REST, the MCP→HTTPS mapping table (memory → services.docdeploy.io/v1/*, documents → mcp.docdeploy.io/rest/*), and troubleshooting. - [Pricing table](https://app.docdeploy.io/api/pricing): Per-call USDC pricing for every route, currency, network, payee, and facilitator. - [OpenAPI 3.1 spec](https://app.docdeploy.io/api/openapi.json): Full request/response shapes for every paid route, with `x-x402-*` price extensions. - [MCP tool inventory](https://mcp.docdeploy.io/schema.json): The 11 MCP tools with input json-schema and per-tool USDC price. - [Memory Schema v1](https://services.docdeploy.io/v1/schema): Free. Canonical kind taxonomy, frontmatter shape, link conventions, and worked example agents should follow when writing memories. Also describes the **free-tier ceiling** (100 w
