Tool Catalog

Payment wires: every paid endpoint accepts x402 and MPP (Machine Payments Protocol) on the same 402 - see Paying with x402 and Paying with MPP. Agent402 is the applied layer of Agentic Finance: agents that pay and get paid on their own.

500+ endpoints, 70+ of them multi-tool Skill Packs. Most tools are deterministic code with full input/output schemas; the model-backed ones (the /v1 model gateway, the report products, and the media, speech, embedding and answer tools) carry modelBacked: true in /api/pricing and are priced as such. Discover them machine-readably (don't hardcode this page):

• /api/find?q={task} - resolve a plain-language task to the right tool (route, price, schema, ready example) in one call, so an agent skips the token-heavy "search to find a tool" step. Also the catalog.find MCP tool on the connector.
• /api/pricing - slug, route, price, category, description for everything
• /openapi.json - OpenAPI 3.1 with schemas
• /tools - human-readable docs, one page per tool with a working example
• x402 Bazaar discovery extension - every 402 response self-describes

The headline tools

These exist because an agent mid-task cannot give itself a browser, a paid search index, or a disk. Most are wallet-only; the API-kit and image-transform rows are pure-CPU and also payable with proof-of-work:

Crypto derivatives, DeFi and Solana intel

Market structure an agent can read directly, as deterministic reads at per-call prices (the caller holds no API key for any of them). Every one is on the same x402 / MPP 402 as the rest of the catalog.

site-map, site-crawl	$0.005, $0.02	Whole-site structure on demand: enumerate a site's URLs from robots.txt, its sitemaps and internal links, then crawl breadth-first to clean markdown under hard page, depth and time budgets

Images and video (flat per call)

Generation priced per picture or per clip rather than per token, on the OpenAI wire, so the cost of a call is known before it is made. Point any OpenAI SDK at base_url https://agent402.tools/v1.

Endpoint	Price	What you get
POST /v1/images/fast	$0.02	Budget text-to-image, about two seconds a picture, inline base64 out
POST /v1/images/pro	$0.05	Higher-fidelity text-to-image, one picture a call
POST /v1/images/generations	$0.08	The flagship image route
POST /v1/videos/generations	$0.20	One silent 4-second 720p clip, MP4 inline base64, 16:9 or 9:16. A failed or timed-out generation is not charged on x402

Report products (outcome-priced, same 402)

When the job is a whole report rather than a call, the /v1 report routes sell one finished, cited report per payment - POST /v1/research ($0.60, pro $0.85, max $1.10), /v1/research/market-brief ($0.85), /v1/dossier ($0.85, max $1.10), /v1/ticker-pack ($2.00), /v1/fund ($0.60, max $0.85), /v1/filing-report ($0.85), /v1/domain-audit ($0.60, pro $0.85), /v1/recall-report ($0.60), /v1/insider-report ($0.60), /v1/token-brief ($0.60), /v1/token-risk ($0.60, pro $0.85), /v1/linkedin-article ($1.10, a publish-ready article package with images at LinkedIn's sizes), and the deterministic /v1/ipo-report digest ($0.05). Same x402 / MPP 402 as every other route, plus prepaid card credits; people buy the same reports by card at /reports for $2 to $5, a price that includes payment processing. Inputs, cadences and the $5/month monitors are on Reports, Monitors and Credits.

The long tail (pure-CPU, also payable with compute)

150+ utilities at mostly $0.001: hashing/HMAC, base58/base32/base64, JWT decode+verify, UUIDs, CRC32, morse, HTML entities, token-count (exact OpenAI BPE), text-chunk (RAG), json-validate (JSON Schema), jsonl, text stats/dedupe/sort/truncate/diff (Levenshtein), JSON/CSV/YAML conversion and querying, date math and cron calculators, validators (email syntax, IP, IBAN-style checksums…), math/stats, QR codes, and unit-convert - one parametric endpoint (POST /api/unit-convert with {value, from, to}) covering every unit pair across length, mass, volume, area, speed, time, data, pressure, energy, power, angle, frequency, temperature.

unit-convert accepts the other spelling of a unit (plural or singular, British spellings, spaces or underscores, the statute- prefix); an unknown unit is still a 400.

judge ($0.001, listed when the judgment upstream is configured) is the one model-backed tool at this price: a typed judgment over supplied state (a choice from your named options with a probability each, a position on levels you describe, or a yes/no as a probability), up to 8 questions per call, input bounded by bytes.

Why would an agent pay $0.001 instead of writing the code? Because writing, testing, and debugging a CSV parser mid-task burns 10–100× that in tokens - and some sandboxes can't execute code at all.

SQL execution certificates (sql-guard + sql-cert-verify)

Two tools that make "an agent is about to run this SQL against production" a checkable gate rather than a hope:

Tool	Price	What it does
POST /api/sql-guard	$0.004	Reviews one SQL statement against a fixed, published risk catalogue and returns a verdict (pass / warn / block) with the risks named (unbounded UPDATE/DELETE, tautological WHERE, DROP, TRUNCATE, DROP COLUMN, statement stacking, COPY … FROM PROGRAM, GRANT/role changes, session_replication_role and trigger/constraint bypass, writes to pg_catalog). On pass it also returns an Ed25519 certificate binding that verdict to the SHA-256 of the exact statement.
POST /api/sql-cert-verify	$0.001	The gate your database layer calls before it obeys the agent. Checks the signature, the certificate version, the expiry, and that the statement's SHA-256 matches the one certified. Returns {valid, reason, payload} and never throws on a malformed token, so the executor always gets one uniform answer. Pass publicKey to verify a certificate issued by another deployment.

Three design points worth knowing:

• The certificate binds a hash, not a statement. An edited statement, even by one character, no longer matches, so a certificate can't be re-pointed at different SQL.
• Literals and comments are scrubbed before analysis, so the word DROP inside a string is never a false alarm.
• Signing is env-gated. SQL_CERT_SIGNING_KEY (a PKCS8 PEM) is the signing identity. Unset, sql-guard still returns full verdicts and says plainly that it cannot certify. It never returns an unsigned object shaped like a certificate. Rotating the key invalidates outstanding certificates, which live 5 minutes by default.

Honest scope: this is a lexical guard over a published catalogue. It catches the shapes that destroy production data. It is not a SQL parser and cannot know that a WHERE clause names the wrong tenant.

Quality guarantees

• Every endpoint CI can call without a third-party key is re-tested against its own documented example before any deploy reaches production. The metered ones (LLM tiers, search, report products) are kept out of those sweeps so CI never spends upstream; their input probes run in CI instead.
• Tools that can't be served honestly get removed rather than left to take money and 502.
• Input errors are structured: a 4xx naming the invalid field and the expected shape.
