Every agent-payable API.

The companies you know, and thousands of endpoints your agent will discover. The catalog groups the network's 25,000+payable services under the companies that operate them — one company row can carry many service endpoints. Placement can't be bought.

GridHub Electricity Data
Historical price time series for one electricity zone, oldest-first, max 31 days per call (start/end are Unix seconds; default last 24h; limit caps rows). Use for trends and backtests; use /v1/latest or /v1/brief for current values. Zone ids from /v1/zones.

GridHub Electricity Data
Interpretation-ready snapshot of one electricity zone: current wholesale price and demand (plus carbon intensity for GB) each ranked against the zone's own trailing 30-day distribution, 24h trend, and a one-sentence summary. Use for 'is power cheap or expensive in {zone} right now'. Zone ids from /v1/zones.
grid-hub.app-$0.02listed
GridHub Electricity Data
Most recent value of every metric one electricity zone publishes (wholesale price, demand, interchange; generation mix for GB and US-CAISO; carbon intensity for GB), each with unit and timestamp. Note European day-ahead prices can carry a timestamp up to ~36h ahead. Zone ids from /v1/zones.
grid-hub.app-$0.001listed
GridHub Electricity Data
Current headline values (price, demand, and where published carbon intensity) for all 25 GridHub zones in one call. Use to compare or rank grids right now; rebuilt every 5 minutes. For one zone with context use /v1/brief/{zone}.

Grok Pricing Table API
Grok pricing table: what every Grok model costs per token right now — Grok 4, Grok 4 mini, Grok 3 — from xAI and every provider that resells or hosts them (Bedrock, Azure, Vertex, OpenRouter, Fireworks). Input, output, cache and batch USD per 1M tokens, sorted cheapest first, so you can compare Grok inference cost across hosts and pick the cheapest place to run one. Normalized, cross-checked, refreshed hourly.

HALOWERK Agent Tools
Builds the cohort table from the events you pass: users grouped by the period of their first event, counted again in each following period. Returns the table per cohort, a retention curve across all cohorts, and, where events carry a value, cumulative value and value per user. The curve counts only cohorts old enough for a given period, so a young cohort is not scored as churn. Day, week and month are real calendar periods. Nothing is fetched, nothing is stored.

HALOWERK Agent Tools
Walks the events you pass through the ordered steps you name and reports per step: how many arrived, conversion from the previous step and from the first, drop-off in users and as a rate, and time to the next step as median, p90 and mean. A step counts only if it happened after the one before and inside the window. Where events carry a segment, each is tested against the largest with the same two-proportion test the A/B endpoint uses. Nothing is stored.

HALOWERK Agent Tools
Reads one conversion experiment two ways at once. Frequentist: two-proportion test, p value, confidence interval on the absolute lift, and the sample size the requested minimum detectable effect needs at the requested power. Bayesian: Beta-Binomial posteriors, probability the variant is better, expected loss either way, credible intervals - closed form, not sampled, so the numbers repeat exactly. looks_taken carries the adjusted threshold and the rate you actually ran at.

HALOWERK Agent Tools
Runs three detectors over one series and reports what each saw: a robust z score on median and median absolute deviation, a robust seasonal-trend decomposition with a z score on the residual, and an isolation forest over value and step-to-previous. Every score is returned per point, so callers set their own threshold instead of trusting a verdict. The forest draws from a fixed seed: same request, same result. Under three full cycles the seasonal figure is marked as not robust.

HALOWERK Agent Tools
Turns SenML (JSON or CBOR) and LwM2M TLV into one record shape: resolved name, unit, absolute timestamp, typed value. Optionally puts every series on a shared time axis with a chosen interval and fill rule (last value, bucket mean, linear). Works only on the payload you pass: no device is contacted, nothing is stored, the same request returns the same bytes. TLV carries no type on the wire; unmapped resource ids come back as opaque base64 with a warning instead of a guess.

HALOWERK kettenwerk
Checks one address on Ethereum, Base, Arbitrum, Optimism, Polygon or BNB Smart Chain against the open verification registry and against the chain itself. For a proxy the answer is deliberately split in two: whether the proxy is verified says almost nothing, whether the implementation it currently points to is verified is the real question, and both are reported separately with the implementation address read from the EIP-1967 storage slot, the EIP-1167 clone pattern or an implementation() call —

Reads the public perpetual data of Binance USDⓈ-M Futures, Bybit linear and OKX swaps for one BASE/QUOTE pair. Settlement intervals differ per exchange and per contract, so annualized_pct is only computed after normalising to the interval that exchange actually uses, and the formula is part of the answer. current_rate and predicted_rate are strictly separate: where an exchange publishes no forecast, predicted_rate stays null and the reason is named instead of reusing the current rate. next_settl

Limits, and they are the important part: error rate over 24 hours, uptime over 7 days and latency percentiles CANNOT be delivered.

Signatures are verified cryptographically against the address each voucher claims to be signed by, in EIP-712 form when the typed data is supplied, otherwise as a plain message signature. Double spending is the expensive case and is checked in full: every voucher id occurring more than once is reported with all its occurrences and whether the duplicates agree on the amount.
