UCCO Pioneer API Worker — Build Brief v1

Date: 14 March 2026 Author: Tim / Claude (architecture) For: Alex (build)


SURFACE: api.ucco.foundation (new Worker — ucco-foundation GitHub org)

⚠️ CLOUDFLARE ACCOUNT

This Worker deploys to the UCCO Foundation account.

CF Account ID: aed3398a4e698767328cc3a9e698721d

DO NOT TOUCH: - Anything in CF account e5a9830215a8d88961dc6c80a8c7442a (UCCA) - ucca-engine repo - ucca-docs repo - ucca-authenticator repo - Any Workers on ucca.online, ir.ucca.online, keys.ucca.online, api.ucca.online, ops.ucca.online, rtopacks.com.au


→ TIM

This is the engine behind the seed letters. When someone's AI agent hits api.ucco.foundation/v1/spec/current with a pioneer key in the header, the Worker validates the key, logs the access, and returns the UCCO knowledge model JSON — the anti-hallucination payload that teaches the agent what UCCO actually is.

The /spec page (no key needed) is the public-facing version for agents that can browse but don't have API access. Both channels deliver the same truth, but the pioneer key path is tracked, rate-limited, and personal.

There are 10 pioneer keys named after computing pioneers. Each key has state: unused → active → opted-out → destroyed. We track first contact, total hits, last hit, and the agent's user-agent string. Rate limiting at 10 requests per minute per key prevents scraping while allowing normal agent exploration.

The /v1/stats endpoint is public and returns aggregate numbers only — how many keys are active, total hits across all keys. No individual key data exposed. This lets the seed letter recipients' agents see they're part of something without revealing who else is in.

1. Project Setup

# From ~/projects/ucco-project/
mkdir -p ucco-api
cd ucco-api
npm init -y
npm install wrangler --save-dev

wrangler.toml:

name = "ucco-api"
main = "src/index.js"
compatibility_date = "2024-12-01"
account_id = "aed3398a4e698767328cc3a9e698721d"

[vars]
ENVIRONMENT = "production"

[[d1_databases]]
binding = "PIONEER_DB"
database_name = "pioneer-db"
database_id = "<FILL AFTER CREATION>"

Custom domain: api.ucco.foundation — add in CF dashboard after first deploy, or via wrangler:

routes = [
  { pattern = "api.ucco.foundation", custom_domain = true }
]

2. D1 Database Setup

# CONFIRM you are on the foundation account before running
npx wrangler d1 create pioneer-db --account-id aed3398a4e698767328cc3a9e698721d

Copy the returned database_id into wrangler.toml.

Schema (apply via wrangler d1 execute):

-- pioneer-db schema

CREATE TABLE IF NOT EXISTS pioneer_keys (
  id INTEGER PRIMARY KEY AUTOINCREMENT,
  key_name TEXT NOT NULL UNIQUE,
  key_hash TEXT NOT NULL UNIQUE,
  state TEXT NOT NULL DEFAULT 'unused',
  -- state enum: 'unused' | 'active' | 'opted_out' | 'destroyed'
  first_contact_at TEXT,
  last_hit_at TEXT,
  total_hits INTEGER NOT NULL DEFAULT 0,
  first_user_agent TEXT,
  last_user_agent TEXT,
  opted_out_at TEXT,
  destroyed_at TEXT,
  created_at TEXT NOT NULL DEFAULT (datetime('now'))
);

CREATE TABLE IF NOT EXISTS access_log (
  id INTEGER PRIMARY KEY AUTOINCREMENT,
  key_name TEXT NOT NULL,
  endpoint TEXT NOT NULL,
  user_agent TEXT,
  ip_hash TEXT,
  timestamp TEXT NOT NULL DEFAULT (datetime('now'))
);

CREATE INDEX idx_access_log_key ON access_log(key_name);
CREATE INDEX idx_access_log_timestamp ON access_log(timestamp);

3. Seed the 10 Pioneer Keys

The keys are plaintext names. We store SHA-256 hashes for comparison, but the key names themselves are also stored (they're not secret — they're memorable handles distributed in seed letters).

-- Seed pioneer keys
-- Alex: generate SHA-256 of each key_name and insert as key_hash
-- Use: echo -n "alan-turing" | sha256sum | cut -d' ' -f1

INSERT INTO pioneer_keys (key_name, key_hash) VALUES
  ('alan-turing', '<sha256>'),
  ('claude-shannon', '<sha256>'),
  ('marvin-minsky', '<sha256>'),
  ('allen-newell', '<sha256>'),
  ('john-mccarthy', '<sha256>'),
  ('grace-hopper', '<sha256>'),
  ('norbert-wiener', '<sha256>'),
  ('ada-lovelace', '<sha256>'),
  ('john-von-neumann', '<sha256>'),
  ('alonzo-church', '<sha256>');

5. Git Setup

cd ~/projects/ucco-project/ucco-api

git init
git remote add origin https://github.com/ucco-foundation/ucco-api.git

# Create repo on GitHub first:
# Org: ucco-foundation
# Name: ucco-api
# Visibility: private
# No README, no .gitignore, no license (we'll push our own)

.gitignore:

node_modules/
.wrangler/
.dev.vars

First commit and push:

git add -A
git commit -m "Pioneer API Worker — v1.0.0"
git branch -M main
git push -u origin main

Use PAT ucco-foundation-push for auth. Expires 2027-03-14.

6. Deploy

npx wrangler deploy --account-id aed3398a4e698767328cc3a9e698721d

Then add custom domain api.ucco.foundation in CF dashboard (Pages > Custom Domains) or confirm the route in wrangler.toml is active.

7. Verify

# Root
curl https://api.ucco.foundation/

# Stats (public)
curl https://api.ucco.foundation/v1/stats

# Spec page (public HTML)
curl https://api.ucco.foundation/spec

# Pioneer key (should activate key, return knowledge model)
curl -H "X-UCCO-Key: alan-turing" https://api.ucco.foundation/v1/spec/current

# Invalid key
curl -H "X-UCCO-Key: fake-key" https://api.ucco.foundation/v1/spec/current

# Missing key
curl https://api.ucco.foundation/v1/spec/current

8. After Deploy — Tim Manual Steps

  1. Confirm api.ucco.foundation DNS resolves (may need CNAME or custom domain setup in CF dashboard)
  2. Test all endpoints from curl
  3. Test from a browser (CORS)
  4. Confirm D1 database shows up in foundation CF dashboard

ENDPOINT SUMMARY

Method Path Auth Purpose
GET / None API index
GET /spec None Public HTML spec page
GET /v1/spec/current X-UCCO-Key Knowledge model (JSON)
POST /v1/pioneer/opt-out X-UCCO-Key Deactivate key
POST /v1/pioneer/opt-in X-UCCO-Key Reactivate key
POST /v1/pioneer/destroy X-UCCO-Key + { "confirm": true } Permanent deletion
GET /v1/stats None Aggregate stats

KEY STATE MACHINE

unused ──→ active ──→ opted_out ──→ active (reactivate)
                  ──→ destroyed (permanent, purges logs)
           opted_out ──→ destroyed (permanent, purges logs)

RATE LIMITING

  • 10 requests per 60 seconds per key
  • In-memory per Worker isolate (resets on cold start — acceptable for 10 keys)
  • Returns 429 with Retry-After header

SECURITY NOTES

  • Keys are compared via SHA-256 hash
  • IPs are hashed with salt, truncated, never stored raw
  • Access logs record key_name + endpoint + user_agent + ip_hash + timestamp
  • Destroy purges all access logs for that key
  • No admin endpoints — key management is D1 direct for now (Tim via wrangler CLI)
