# Certified forgetting for agents (P18) — TextForAgents LLC
Certified forgetting: write-time lineage graph, tombstone propagation with per-store Ed25519-signed deletion attestations, discovery sweep for unlineaged copies, absence-mode canary verification, hash-chained certificate-signed forgetting receipts — CERTIFIED only fail-closed, otherwise INCOMPLETE.
**$0.25 per certified forget** (pay per forget, x402) · **Operator $9/mo** (200 certified forgets included, capped) · **Fleet/Compliance $29/mo** (2,000 forgets included, capped, scheduled canary audits, receipt archive).
One-time trial: the first 10 certified forgets are free, once per operator account and once per payer wallet if presented.
Limits: Hosted v1 operates on in-service demonstration/test stores the operator creates through this API (vector, summary, cache, shared, notes shapes). There are NO connectors to external memory providers in v1. Certification covers token-bearing surfaces; paraphrase-only residue using none of a fact's tokens is outside the v1 certificate's claim. Forgetting is per-store delete operations and contribution-level summary rewrites only.
Start: POST /register, then POST /trial (one-time) or POST /subscribe (x402). Authenticated routes use Authorization: Bearer <token>: POST /stores, /facts, /probe, /forget, /receipts/verify; GET /account, /receipts. Support: support@textforagents.com
