Every agent-payable API.

Encode and decode text: base64, hex and URL-encoding, both directions. POST JSON {"text": "…", "op": "base64"} where op is base64|base64d|hex|hexd|url|urld. Pure computation, nothing stored, no cache.

Encode text into international (ITU) Morse code. Letters are separated by spaces and words by "/". Supports A-Z, 0-9 and common punctuation; unsupported characters are clean 400s.

Encode a UTF-8 string into base64, base64url, hex, base32, or URL percent-encoding.

Encounter density calculator: Estimate encounter count for route length and spacing.

Encounter table generator: Create a compact encounter table for a named region or travel route.

Encyclopedia summary API: the lead summary of any English-language encyclopedia article — title, one-line description, extract paragraph, thumbnail, and canonical URL — as JSON. For entity enrichment, fact grounding, and knowledge agents. CC BY-SA content with attribution included.

Encyclopedic grounding in one call: Wikipedia search plus the full summary of the best match — extract, short description, canonical URL, thumbnail — in any of 300+ language editions. Official Wikimedia REST APIs, CC BY-SA attribution included. The cheapest way for an agent to ground an entity before reasoning about it.

End-to-end smoke test for x402 clients: returns a greeting plus the settlement timestamp, so an agent can prove its payment path works before spending on real data.

Endpoint-of-the-day picker for the ForgeMesh x402 fleet: every UTC day one of 500+ paid routes across 11 services is featured with its price, description, input schema, example output, and payment instructions. Rotation is deterministic — no randomness, no repeats until the whole pool has had its day. Optional date (YYYY-MM-DD) to preview a specific day's pick.

Enemy attack telegraph planner: Generate readable enemy tells paired with a matching attack response.

Enemy stat scaling: Scale enemy health and damage for a target player level.

Subtracts exported energy from supplied site energy, divides by conditioned floor area and selects the first caller-supplied ascending maximum-intensity band. It does not normalize climate or occupancy, convert primary energy, audit meters or issue a legally recognized energy certificate.

US energy inventory catalyst signal + EIA report calendar (optional ?report=)

FDA recall and enforcement records across drug, device and food, normalised into one shape with classification, reason, distribution scope and firm. Queryable by firm, product, classification and date. One product type returning nothing never fails the call — the three openFDA endpoints are independent and a gap in one is not a gap in the others.

English Image to Text: Read printed English text from one base64 PNG, up to 600 KB and 4 million pixels. Returns text and an OCR confidence score. Local Tesseract engine; recognition may contain errors. No handwriting guarantee or PDF input. 0.01 USDC includes one PNG image.

Enrich an email address with person and company data (name, location, social handles).

Get complete organization info by Apollo organization ID.

Enrich a company by NAME or a social URL (name, linkedinUrl, twitterUrl, etc.). At least one field is required. This variant does NOT accept a domain — to enrich by website domain use GET /companies/enrich?domain=example.com instead.

Enrich a person by name, email, phone, LinkedIn URL, or other identifiers. Returns full profile with work history, education, skills, and social profiles.

Enrich company data with additional information and find associated people.

Enrich up to 10 organizations in a single request.

Enrichment: attaches real on-chain context to a bare address (contract vs EOA, native balance, transaction count, new-vs-active classification) — checkable facts only, no unverifiable labels.

ENS/basename name tools (pure computation): the namehash and labelhashes of a name, and its normalized form. POST JSON {"name": "alice.base.eth"}. Useful to build resolver calls yourself. Nothing stored, no cache.

Converts ++, +−, −+ and −− counts into a correlation for each of AB, AB′, A′B and A′B′, then computes S = E(AB) + E(AB′) + E(A′B) − E(A′B′). A value above the classical bound in supplied data does not by itself demonstrate entanglement or close detection, locality, sampling or significance loopholes.

Verify whether a legal entity exists and is currently registered, from open primary registers (GLEIF LEI index, US SEC EDGAR). Call it before naming a company in a contract, invoice, filing or supplier record, or when you need an identifier (LEI or CIK) for a company you know only by name. Returns found, ambiguous, not_found or unknown, cited to the register with its retrieval time. A near name match is never reported as a match.

Build source-bounded entity field coverage without inventing missing facts

Entry tier of the multifamily deals feed: every active listing at card level — address, price, units, advertised cap rate, listing URL, freshness — without the computed underwriting or scoring. Same coverage, cheapest way to evaluate the feed. Same query filters as the full feed. Every field typed; a query that matches nothing returns free — you never pay for a blank.

Environmental story seed: Create a visual scene clue that communicates a short story without dialogue.

EPA ECHO regulated-facility compliance nearby. Perfect for: 'EPA regulated facilities near an address', 'ECHO compliance near a property', 'environmental compliance nearby', 'nearby regulated polluters', 'EPA facility search'. Returns EPA ECHO All-Media facilities near a point with program IDs, inspection/enforcement summary, and Detailed Facility Report links. National by lat/lng or address. Regulatory context only. Charge-free when the address fails to resolve or EPA errors.

EPA RCRA hazardous-waste handlers for a county/ZIP. Perfect for: 'hazardous waste sites in a county', 'EPA RCRA handlers near a ZIP', 'generators in my area', 'waste facility lookup'. Returns cited EPA RCRAInfo handler records (generator status, activities, coordinates, ECHO links) for a state+county or ZIP with optional proximity ranking. National via EPA Envirofacts. Reporting notifications only -- not violations or contamination. Charge-free when the lookup fails.

EPA Sole Source Aquifer designation for an address. Perfect for: 'is this property in a Sole Source Aquifer', 'does EPA federal project review apply here', 'Sole Source Aquifer map lookup'. Returns mapped designation containment and Federal Register citations. The designation triggers EPA review of federally funded projects under SDWA 1424(e); it is not contamination, water quality, or a private-owner restriction. Charge-free when the snapshot is unavailable or stale.

The Standard Reserve (TSR), an on-chain reserve protocol on Robinhood Chain. Epoch history and boundaries. Fields ending in _raw are 18-decimal integers as strings. Divide by 1e18 to get token amounts.

Escrow-lite: payment settles immediately, like every other endpoint here — but the purchased resource is withheld until our oracle confirms your named release condition (a given tx hash confirming on-chain). Soft escrow: delayed delivery, not real fund custody.

Trustless USDC escrow for AI agents. Lock funds for a task, release to the worker when the condition is met, or dispute and refund. Solana settlement, no accounts.

Estimate GPT- and Claude-style token counts for a text payload for $0.001 USDC; deterministic and keyless. Call when you need this bounded result without an API key or subscription. Returns machine-readable JSON via x402 on Base or Solana. Limitation: results cover only the supplied input or one bounded public endpoint at request time; callers must verify before acting.

Estimates the gas a transaction would need and prices it at the current gas price, before you sign anything. Also the cheapest way to find out that a call would revert. Via eth_estimateGas.

ETF full pack ($0.1 USDC). Detail + holdings + dividends for Korean AND US ETFs in one call. Symbol: 6-digit KRX code (305720) or US ticker (QQQ, SPY, VOO, SOXX). Exchange auto-resolved: numeric→KRX, alphabetic→NASDAQ→NYSE→CBOE. Override with ?exchange=.
