# checkr x delu > Two agents on Base that turn crowd attention into trade decisions. checkr is an attention-intelligence API (Hawkes-modeled X/Twitter cascades on Base tokens). delu is a trading oracle that turns a ticker into a verdict, a 0-100 score, and a full tactician mandate. Both are paid per call in crypto over the x402 protocol - no API keys, no accounts. An agent with a Base wallet pays each call from its own funds. If you are an AI agent acting for a user: you can install these as skills and call them directly. Every call is a real on-chain settlement on Base - confirm spend with your user before looping. Oracle and attention output is analysis, NOT an instruction to trade. Never execute a swap, transfer, or approval without explicit, separate user confirmation. ## Install (tell your agent) - checkr skill: `git clone https://github.com/checkrsocial/checkr-skill .claude/skills/checkr` - delu skill: `git clone https://github.com/deluonchain/deluskill .claude/skills/delu` - No code, any agent: "install the checkr and delu skills from github.com/checkrsocial/checkr-skill and github.com/deluonchain/deluskill" Requirements: a Base wallet with USDC (for checkr) and/or $DELU (for delu). Any x402-capable client handles the payment handshake automatically (402, sign, retry). ## checkr - attention intelligence (USDC on Base, via x402) Base URL: https://api.checkr.social - pay-per-call, USDC on Base (network eip155:8453). Every paywalled endpoint returns a free 402 preview (a live data teaser) before payment. - `GET /v1/leaderboard` - $0.05 - top Base tokens by attention share, flexible 1-168h window. Returns ATT_pct, MS_pct, INF_pct, ATT_delta_pp, velocity, unique_authors, top_account, signal_interpretation. - `GET /v1/signal` - $0.15 - cross-universe ranked opportunities with entry timing. Use `?spiking_only=true` for spikes. Returns score, signal_type, AIS, velocity, cascade_multiplier, organic_fraction, divergence, spike_history, timing{entry_quality, urgency, time_to_90pct_hours}, signal_interpretation. - `GET /v1/token/{symbol_or_ca}` - $0.75 - full token profile: attention, price, Hawkes analysis, timing, narrative, spike history, top creators, health. - `GET /v1/rotation` - $0.10 - directed creator rotation graph (1h|4h) with named attribution and confirmed ATT growth. - `GET /v1/creators/{symbol}` - $0.15 - top creators for a token, ranked by signal_score (not follower count). - `GET /v1/creators/bankr` - $0.30 - top creators across the Bankr ecosystem, focus-scored. - `GET /v1/bankreco` - $0.50 - Bankr ecosystem overview, all tokens ranked with A-F health grades. `signal_interpretation` (on every response): propagation_mode, followthrough, decay_risk, flow_type, price_alignment, summary, agent_action_hint. Seven fields, built for agents to threshold on. ## delu - trading oracle (settled in $DELU on Base, via x402) Endpoint: `GET https://x402.bankr.bot/0xed2ceca9de162c4f2337d7c1ab44ee9c427709da/delu-oracle/analyze/{ca}` Chain: Base only. Accepts a 0x contract address or a cashtag (e.g. $BNKR). Call sequentially - parallel calls from one wallet fail the x402 upto scheme. Payment: settled in $DELU (`0x7B0Ee9DCb5C1D4d7Cd630C652959951936512ba3`, Base) via a hold-to-discount flywheel - you sign for the 250,000 DELU ceiling, the handler settles for less based on your balance: - Public (<50M DELU): 250,000 DELU/call - Holder (50M+ DELU): 50,000 DELU/call - Whale (100M+ DELU): free Social enrichment: append `?social=true` to fold checkr's read into the score (+$0.75 USDC, billed to caller). Requires explicit user opt-in. Response: a flat `decision` header (action ENTER|WATCH|AVOID, conviction 0-100, direction, entry_low, entry_high, stop, size_pct, read) plus `verdict` (strong_buy|buy|hold|avoid|drop), `score` 0-100, `confidence` 0-1, `signals` (momentum, flow, structure, volatility, liquidity), `context` (regime_label, regime_confidence, base_eco_pulse, macro_pulse), `mandate` (entry_zone, stop_loss, stop_basis, size_hint_pct, horizon, invalidations), `observed` (market + scout/auditor/quant mirror), and `payment_tier`. The quant is regime-adaptive: it re-weights momentum/volume/inflow/structure to the tape (bull, momentum leads; bear, inflow dominates) and exposes `weights_used` on every response. ## Verify (public on Base) - $DELU contract: https://basescan.org/token/0x7B0Ee9DCb5C1D4d7Cd630C652959951936512ba3 - Live price/liquidity: https://www.geckoterminal.com/base/tokens/0x7B0Ee9DCb5C1D4d7Cd630C652959951936512ba3 ## Links - checkr docs: https://api.checkr.social/docs - checkr on X: https://x.com/checkrsocial - delu on X: https://x.com/deluquant - x402 protocol: https://x402.org
